INTRODUCTION

The HD2102.1 and HD2102.2 are portable instruments with a large LCD display.

They measure illumination, luminance, PAR and irradiance (across VIS-NIR,

UVA, UVB and UVC spectral regions or in the measurement of effective irradiance

according to the UV action curve).

The probes are fitted with the SICRAM automatic detection module: in addition to

detection, the unit of measurement selection is also automatic. The factory calibration

settings are already memorized inside the instruments.

In addition to instantaneous measurement the instruments calculate the acquired

measurements time integral Q(t). Some thresholds can be associated with the

integrated measurement and with the integration time, which can be set in the menu.

When exceeded these thresholds cause the instrument to stop the integral calculation.

The HD2102.2 instrument is a datalogger. It memorizes up to 38,000 samples which

can be transferred from the instrument connected to a PC via the multi-standard

RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be

configured using the menu.

The HD2102.1 and HD2102.2 models are fitted with an RS232C serial port and can

transfer the acquired measurements in real time to a PC or to a portable printer.

The Max, Min and Avg function calculate the maximum, minimum or average values.

Other functions include: the relative measurement REL, the HOLD function, and the

automatic turning off that can also be disabled.

The instruments have IP67 protection degree.

This manual describes the HD2102.1 and HD2102.2 models: if not otherwise

specified, the description is intended to be applicable to both models.

KEYBOARD AND MENU DESCRIPTION

Foreword

The instrument keyboard is composed of single-function keys, like the MENU key, and doublefunction

keys such as the ON-OFF/Auto-OFF key.

In the double-keys, the function in the upper part is the “main function”, while the one in the bottom

part is the “secondary function”. When the instrument is in standard measurement mode, the main

function is active. In the menu or in conjunction with the FUNC key, the secondary function is

enabled.

The pressing of a key is accompanied by a short confirmation beep: a longer beep sounds if the

wrong key is pressed.

Each key specific function is described in detail below.

ON-OFF/AUTO-OFF key

The instrument is turned on and off using the ON/OFF key. The turning on enables all display

segments for a few seconds, starts an auto-test including the detection of the probe connected to the

input, and sets the instrument ready for normal measurement.

If during turning on no probes are connected, the message PROB ERR is displayed.

When the probe is inserted into a functioning instrument, it is not detected. As the probe's

data are captured upon turning the instrument on, it is necessary to turn the instrument off

and on again.

Replace the probes when the instrument is off.

+

Automatic turning off

The instrument has an AutoPowerOff function that automatically turns the instrument off after about

8 minutes if no key is pressed during the intervening time. The AutoPowerOff function can be

disabled by holding the HOLD key pressed down during the entire turning on phase: the battery

symbol will blink to remind the user that the instrument can only be turned off by pressing the

<ON/OFF> key.

The automatic turning off function is disabled when external power is used. On the other hand, it

cannot be disabled when the batteries are discharged.

- 8 -

FUNC/ENTER key

During normal measurement this enables the display and logging of the maximum (MAX),

minimum (MIN) and average (AVG) value of the measurements captured by the probe connected to

the instrument, updating them with the acquisition of new samples. The acquisition frequency is

once a second.

The MAX, MIN and AVG measurements remain in the memory until the instrument is on, even

after exiting the calculation function. To reset the previous values and restart with a new

measurement session, press FUNC until the message “FUNC CLR” appears, then use the arrows to

select YES and confirm using ENTER.

In the menu, the ENTER key confirms the current parameter and then goes to the next one.

Pressed together with the UNIT-Q/T key, enables the integral Q(t) calculation function.

Pressed together with the MENU-Clear Q/T, resets the previous integral Q(t) calculation (please see

the description of the UNIT key).

Attention: the data captured using the Record function cannot be transferred to the PC.

HOLD key/􀀘

It increases the current parameter when used in the menu; when used in measurement mode, it

freezes the measurement in progress, and upon application of pressure on the key, the message

HOLD appears in the upper side of the display. To return to the current measurement, press the

key again.

Upon turning on the instrument, the AutoPowerOff function can be disabled by holding the HOLD

key down (please see the ON-OFF key description).

During calculation of the integral Q(t), by pressing the key the displayed value is frozen without

suspending the calculation in progress.

UNIT/Q(t) key

During measurement and integral Q(t) calculation, allows selection of the unit of measurement.

Repeatedly pressing this key displays the available units of measurement according to the type of

connected probe, as reported in the following table.

which the integral calculation is stopped.

5. Management of memorized data (only HD2102.2): the message

“>>>_LOG_DUMP_or_ERAS” (Transfer data or erase) is scrolled in the comment line.

The center figure reports the number of free memory pages (FREE). All memory data are

permanently erased by pressing SERIAL/EraseLOG. By pressing LOG/DumpLOG, the data

transfer of the logged data on the serial port is started: the “BAUD-RATE” must have

previously been set to the maximum value (please see the menu items described below and

the paragraph "STORING AND TRANSFERRING DATA TO A PERSONAL

COMPUTER" on page 21).

6. Sleep_Mode_LOG (Automatic turning off during recording) (only HD2102.2): this

function controls the instrument's automatic turning off during logging, occurring between

the capture of a sample and the next one. When the interval is lower than 60 seconds, the

instrument will always remain on. With intervals greater than or equal to 60 seconds, it is

possible to turn off the instrument between loggings: it will turn on at the moment of

sampling and will turn off immediately afterwards, thus increasing the battery life. Using the

arrows select YES and confirm using ENTER in order to enable the automatic turning off,

select NO and confirm to disable it and keep the instrument on continuously.

Note: even if Sleep_Mode_LOG=YES is selected, the instrument does not turn off for less

than one minute intervals.

7. Print and log interval: sets the interval in seconds between two loggings or data transfers

to the serial port. The interval can be set at 0, 1s, 5s, 10s, 15s, 30s, 60s (1min), 120s (2min),

300s (5min), 600s (10min), 900s (15min), 1200s (20min), 1800s (30min) and 3600s (1hour).

If the value 0 is set, SERIAL works on command: the sending of data to the serial port

is performed each time the key is pressed. Recording (LOG) is performed with one

second intervals even if the interval is set to 0. With an interval from 1 to 3600s, continuous

data transfer is started when the SERIAL key is pressed. To end the recording (LOG) and

continuous data transfer operations (SERIAL with an interval greater than 0), press the

same key again.

8. YEAR: to set the current year. Use the arrows to modify this parameter and confirm using

10. DAY: to set the current day. Use the arrows to modify this parameter and confirm using

ENTER.

11. HOUR: to set the current hour. Use the arrows to modify this parameter and confirm using

ENTER.

12. MIN (minutes): to set the current minutes. In order to correctly synchronize the minute, it is

possible to reset the seconds by pressing the UNIT key. Use the arrows to set the current

- 1 1 -

minute plus one, and as soon as that minute is reached press UNIT: this synchronizes the

time to the second. Press ENTER to go onto the next item.

13. BAUD_RATE: indicates the frequency used for the serial communication with the PC.

Values from 1200 to 38400 baud. Use the arrows to modify this parameter and confirm

using ENTER. The communication between instrument and PC (or serial port printer)

only works if the instrument and PC baud rates are the same. If the USB connection is

used this parameter value is automatically set (please see the details on page 21).

+

Reset integral Q(t)

Simultaneous pressure on the FUNC/ENTER and MENU-CLR Q(t) keys resets the integral Q(t)

and sets the instrument up for the new calculation. Please see the paragraph dedicated to calculation

on page 13.

LOG/DUMP LOG key - only HD2102.2

In measurement mode, this function starts and stops the logging of a data block to be saved in the

instrument's internal memory. The data logging frequency is set in the "Print and log interval"

menu parameter. The data logged between a start and subsequent stop represent a block.

When the logging function is on, the LOG indication is on the display, the battery symbol blinks

and a beep is issued each time a logging occurs; when using an external power supply the

battery symbol does not appear.

To end the logging, press LOG.

The HD2102.2 can turn off during logging between one capture and the next: the function is

controlled by the Sleep_Mode_LOG parameter. When the logging interval is less than one minute,

the logging instrument remains on; with an interval of at least one minute, it turns off between one

capture and the next if the parameter Sleep_Mode_LOG=YES.

The variable appearing on the display upon pressing the LOG key is saved: the variable associated

with the probe connected to the instrument, with its relevant unit of measurement or the integral

Q(t).

>>>

Dump LOG - only HD2102.2

Press the MENU key until the “>>>_LOG_DUMP_or_ERAS” item is displayed and then press on

the LOG key: the transfer of the data contained in the instrument internal memory via the serial port

is started.

Please, see the paragraph dedicated to data transfer on page 21.

SERIAL key - only HD2102.1

SERIAL/EraseLOG key - only HD2102.2

In measurement mode, this function starts and stops the data transfer to the RS232C serial output.

According to the settings entered in the Print and log interval menu item, a single sample can be

printed if Print and log interval=0 or a continuous indefinite printing of the measured data can be

set up if Print and log interval=1…3600.

The printing operation is accompanied by the display of the RS232 symbol and the blinking of the

battery symbol; when using an external power supply the battery symbol does not appear.

Press SERIAL to end the continuous printing.

The variable appearing on the display upon pressing the SERIAL key is printed: the variable

associated with the probe connected to the instrument, with its relevant unit of measurement or the

integral Q(t).

Before starting the printing with SERIAL, set the baud rate. To do so, select the Baud Rate menu

item and select the maximum value equal to 38400 baud by using the arrows. Confirm with

ENTER.

The DeltaLog9 software for PC will automatically set the baud rate value during connection. If you

are using a different program than DeltaLog9, be sure the baud rate is the same for both the

instrument and the PC: the communication will only work in this way.

>>>

Erase memory - only HD2102.2

Press the MENU key until the “>>>_LOG_DUMP_or_ERAS” item is displayed and then press on

the SERIAL/EraseLOG key: this clears permanently all the data contained in the instrument’s

memory.

THE PROBES

The instrument works with probes of the LP471… series: these are photometric and radiometric

probes that measure:

illuminance:
LP471
PHOT

irradiance:
 
LP471 RAD
LP471 UVA
LP471 UVB
LP471 UVC

PAR
LP471 PAR

luminance:
LP471 LUM 2

effective irradiance:
 according to the UV action curve LP471 ERY

All the probes, save the LUM 2, are provided with a diffuser for cosine correction.

Upon turning on the instrument automatically detects the probe connected to the input: it is sufficient to connect it.

If the instrument is already on, turn it off and back on again in order for the probe to be detected.

The unit of measurement is determined according to the probe connected to the input.

In cases where more than one unit of measurement is provided for the same probe, use the UNIT key to select the one desired.

All probes are calibrated in the factory; no calibration is required by the user.

In addition to instantaneous measurement the instrument calculates the acquired measurement time integral Q(t).

Some thresholds can be associated with the integrated measurement and with the integration time, which can be set in the menu.

When exceeded these thresholds cause the instrument to stop the integral calculation.

The probe is detected during turn on, and this cannot be performed when the instrument is

already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it off and on.

Q/TIME INTEGRATION

In addition to instantaneous measurement the instrument calculates the following summation:

(1) Q(t) = Σ u(t)⋅Δt, Δt = 1sec

0

t

where u(t) is the instantaneous value of the input variable compared to time t.

The sampling interval is fixed at 1 second.

As soon as either the Q(t) value or the integration time t reach the set limit, the integration is stopped.

Maximum integration time: 100 hours, 00 minutes, 00 seconds

Integration interval: 1 second

How to set the limits

To set the integration limit, enter the "INTG LIMT ###S" menu item.

Use the arrows to set the desired value.

Confirm by pressing ENTER.

To set the final integration time, enter the TIME LIMT HOUR, TIME LIMT MIN and TIME

LIMT SEC menu items. Use the arrows to set the desired value in hours, minutes and seconds.

Confirm each item using ENTER.

To cancel the limit, set its value to 0.

- 1 4 -

How to perform an integration measurement

After setting the limits, as illustrated above, exit the menu and return to normal measurement.

Simultaneously press FUNC/ENTER and UNIT-Q(t). To start and stop the integral calculation press Start/Stop Q(t).

To cancel the previous integration values and reset it, simultaneously press FUNC/ENTER and MENU/CLR-Q(t):  

if an integration is started without pressing the CLRQ(

t) key, the calculation will continue from the previous values.

The integral calculation can be suspended at any moment pressing Start/Stop Q(t): in this status, to

resume the integration, press the key again.

If one or more limits have been enabled in the menu, on reaching of the first, the calculation stops.

Pressing FUNC/ENTER alternates the display of Q(t) and integration time.

Because the integration process proceeds according to discrete steps, the Q(t) value according to

which the integration is stopped could be slightly different than the set limit, but will be equal to the

first integration value that exceeds the limit.

Note: for the LP471 LUM 2 luminance probe, the integral calculation is not provided.

WARNINGS AND OPERATING INSTRUCTIONS

1. Do not bend the probe connectors or force them upward or downward.

2. Do not bend or force the contacts when inserting the probe connector into the instrument.

3. The sensors and filters should not exceed the temperature limits established with consequent

irreparable degradation of their characteristics.

4. Do not drop the probes: as this could cause irreparable damage.

5. Avoid taking measurements in presence of high frequency sources, microwave ovens or large

magnetic fields; results may not be very reliable.

6. The instrument is water resistant and IP67, but is not watertight and therefore should not be

immersed in water without closing the free connectors using caps. The probe connectors must

LOW BATTERY WARNING AND BATTERY REPLACEMENT

The battery symbol

on the display constantly shows the battery charge status. To the extent that batteries have

discharged, the symbol "empties". When the charge decreases still further it starts blinking…

In this case, batteries should be replaced as soon as possible.

If you continue to use it, the instrument can no longer ensure correct measurement. The memory

data are maintained.

If the battery charge level is insufficient, the following message appears when you turn the

instrument on:

BATT TOO LOW

CHNG NOW

The instrument issues a long beep and turns off. In this case, replace the batteries in order to

turn the instrument back on.

In order to avoid data loss, the logging session is ended, if the HD2102.2 is logging and battery

voltage falls below the minimum operating level.

The battery symbol turns off when the external power supply is connected.

To replace the batteries, switch the instrument off and unscrew the battery cover counter clockwise.

After replacing the batteries (4 1.5V alkaline batteries - type AA) screw the cover on clockwise.

After replacing the batteries, the date, time, baud rate, type of probe, printing interval, logging

parameters must be set again: in order to simplify the operation, on insertion of the new

STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER

The HD2102.1 and HD2102.2 instruments can be connected to a personal computer via an RS232C

serial port, and exchange data and information through the DeltaLog9 software running in a

Windows operating environment. The HD2102.2 can also use the USB connection. Both models

can send in real time input measured values directly to a PC, through the PRINT function; the

HD2102.2 can also store the values measured by using the Logging function (LOG key) in its

internal memory. If necessary, the data stored in the memory can be transferred to a PC later.

THE LOGGING FUNCTION - ONLY FOR HD2102.2

The Logging function allows the recording up to 38,000 measurements registered by the probe

connected to the input. The time interval between two consecutive measurements can be set from 1

second to 1 hour. The logging starts by pressing the LOG key and ends by pressing the same key

again: the data memorized in this way form a continuous block of data.

See the description of the menu item on page 9.

If the automatic turning off option between two recordings (menu >> Sleep_Mode_LOG) is

enabled, upon pressing the LOG key the instrument logs the first data and turns off. 15 seconds

before the next logging instant, it turns on again to capture the new sample, and then turns off.

The data stored in the memory can be transferred to a PC using the DUMP LOG command: press

the MENU key until the “>>>_LOG_DUMP_or_ERAS” item is displayed and then press on LOG

key. During data transfer the display shows the message DUMP; to stop the data transfer press ESC

on the instrument or on the PC.

CLEARING THE MEMORY - ONLY FOR HD2102.2

To clear memory use the Erase Log function (the MENU key until the

“>>>_LOG_DUMP_or_ERAS” item is displayed and then the SERIAL/EraseLOG key).

The instrument starts clearing the internal memory; at the end of the operation, it goes back to

normal display.

NOTES:

Data transfer does not cause the memory to be erased; the operation can be repeated as many

times as required.

• The logged data remain in memory apart from battery charge conditions.

In order to print the data to a parallel interface printer, you must use a parallel-serial adaptor (not

supplied).

The direct connection between instrument and printer via a USB connector does not work.

Some keys are disabled during logging. The following keys work: HOLD, FUNC (Max-Min-

Avg) and SERIAL.

Pressing the HOLD, REL and FUNC keys has no effect on the logged data if these keys are

pressed after starting the recording, otherwise the following is valid.

The recording started with the display in HOLD mode proceeds normally with the actual

measured values (that is, not in “HOLD” mode). Only the display is frozen to the values present

when the HOLD key was pressed.

• The same is true for the Max-Min-Avg function.

• If the logging is started when the display is in REL mode, the relative values are logged.

It is possible to activate both the logging (LOG) and direct transfer (PRINT) functions at the

same time.

- 2 2 -

THE PRINT FUNCTION

The PRINT function sends the measurements taken in real time by the instrument inputs directly to

a PC. Print data units of measurements are the same as those used on the display. The function is

started by pressing SERIAL. The time interval between two consecutive prints can be set from 1

second to 1 hour (please see the Print and log interval menu item on page 9). If the print interval is

equal to 0, by pressing SERIAL the single data is sent to the connected device. If the print interval

is higher than 0, the data transfer continues until the operator stops it by pressing SERIAL again.

NOTES:

• The print out is formatted across 24 columns.

Some keys are disabled during serial transmission. The following keys work: ON/OFF, HOLD,

FUNC (Max-Min-Avg) and LOG.

Pressing the HOLD, REL and FUNC keys has no effect on the printed data if these keys are

pressed after starting the printing, otherwise the following is valid.

The transfer started with the display in HOLD mode proceeds normally with the actual

measured values (that is, not in “HOLD” mode). Only the display is frozen to the values present

when the HOLD key was pressed.

• The same is true for the Max-Min-Avg function.

If the serial transfer is started when the display is in REL mode, the relative values are

transferred.

It is possible to activate both the logging (LOG) and direct transfer (PRINT) functions at the

same time.

Relative Spectral Response

The probe LP 471 ERY measures the effective total irradiance (W/m2

eff ) according to the UV

action curve (CEI EN 60335-2-27). A particular type of photodiode and a combination of special

filters bring the spectral response closer to the UV action curve.

CEI EN 60335-2-27 standards establish a maximum allowable dose of 100J/m2 for first-time

exposure and an annual dose of 15000J/m2.

The typical spectral response curve of LP 471 ERY is shown in the Figure together with the UV

action curve.

The good accordance between the two curves enables the instrument to take reliable measurements

of different types of lamps (and filters) used at present for tuning machines.

Each probe is individually calibrated at DeltaOhm photo-radiometry laboratory by means of a

double monochrome. Calibration is performed at 295 nm through a SIT calibrated reference

photodiode.
