DS-U-2
Receptacle for AC adapter, one USB port, one RS485 port (multi-drop), four probe connectors (HygroClip or analog probe), one connector for up to two digital input signals. This model has an internal electronic circuit 1.
DS-U-4 2
Receptacle for AC adapter, one RJ45 connector (Ethernet), one RS485 port (multi-drop), four probe connectors (HygroClip or analog probe), one connector for up to two digital input signals. This model has an internal electronic circuit 1.
DS-PT-2
Receptacle for AC adapter, one USB port, one RS485 port (multi-drop networking), four connectors for RTD probe (direct 4-wire connection), one connector for up to two digital input signals. This model has an internal electronic circuit 1.
1 The electronic circuit substantially increases the current drawn from the logger battery. Use over extended periods of
time generally requires an external AC adapter.
2 By nature, these models generate enough heat to noticeably increase the temperature of both the docking station and
data logger. Any probe connected to the HygroLog NT should be separated by a length of cable to maintain the
accuracy of the temperature and humidity data. Please also note that these models require too much current to be
powered from the logger battery alone, even over a brief period of time.
HW4 Software
The ROTRONIC HW4 software can be used only with the HygroLog NT. Other ROTRONIC products will added shortly. HW4 is available in two versions:
HW4 Standard Edition: for single users.
Unlimited number of instruments (depends on capabilities of PC and available ports)
On-line display of the measured and calculated values (dew point or other) - limited to a single instrument at a time (instrument may have several probes).
Automatic retention of the most recent data in a temporary on-line buffer.
Logging of measured and calculated values to the PC (can be done simultaneously with local data logging).
Easy-to-read graphs and data tables.
Statistical data: mean, standard deviation, minimum and maximum (off line data only).
Data print-out (table or graph)
Automatic device/instrument recognition and identification
Device/instrument configuration
Adjustment (calibration) of the HygroClip digital probes
Psychrometric Conversion Tool
Built-in security to protect against manipulation of recorded data
HW4 Professional Edition: meets the requirements of FDA 21CFR Part II / GAMP and allows multiple users, with either administrator or standard rights. On each single port (RS-232, USB or TCP/IP), HW4 Professional can monitor up to 64 instruments connected together in a multi-dropped RS-485 network. The number of such networks depends on the number of available ports.
All the functionality of HW4 Standard Edition
On-line display in a single graph of the data from multiple instruments and probes
Overlaying of several log files into a single graph
User Event Logging: automatically keeps track of user activity
Self Event Logging: automatically records eventual software problems to facilitate troubleshooting
Logger Event Logging: automatically records the data logger internal events and configuration changes.
Automatic creation of protocols detailing instrument configuration changes, log function programming and probe adjustments.
Password protected log-in
Indication of an alarm condition when displaying log file data
The following functions will be added to HW4 Professional during 2005 (upgrade will be available on the Internet):
Optical and acoustical indication by the PC of an alarm condition with the option of sending an e-mail or SMS
Automatic reading and archiving on the PC of local log files
A special version of HW4 Professional Edition features OPC tags which can be used to import data into practically any third-party OPC client application.
HW4 Requirements:
Computer/Operating System Requirements:
The following are the minimum values required to install and run HW4 on a computer. It is highly recommended to exceed these values.
Processor: Pentium II, 450 MHz
RAM: 128 MB
Available hard disk space: 50 MB
Monitor: SVGA, 1024 x 768, 256 colors
Ports: one free serial (COM) port or one free USB port or Network Interface Card (Ethernet)
Operating System Compatibility:
Windows 98, XP, NT4 with SP 6a or higher
Windows 2000 with SP 2 or higher
Windows Server 2003
HW4 was written for the Microsoft .NET framework and requires this framework to be installed on the computer. The .NET framework offers significant improvements in the areas of networking and user security. When new software is being installed, the .NET framework also eliminates the potential problem of conflicting dynamic library files (DLL).
Networking
The ROTRONIC HW4 software allows the on-line monitoring on a PC of an almost unlimited number of networked data loggers, the programming of the data logging function (for each logger and/or on the PC), the downloading and visualizing of the recorded data, the adjustment of any HygroClip probe connected to the HygroLog NT and the configuration of the HygroLog NT itself. When data has to be centralized into a single third-party application, a special version of HW4 features OPC tags. In principle, these tags can be read by practically any OPC client application (of-the-shelf or custom designed).
Connecting the HygroLog NT to a network allows you to remotely monitor and record data on a PC (using a local network or via Internet). This can be done either with the HW4 software or with your own custom application (see HygroLog NT communications protocol). In the event of a power outage, protection against loss of data can be provided by simultaneously recording data both on the HygroLog NT and on the remote PC. Whenever required, the log files located on the HygroLog NT can be downloaded to the remote PC, using either HW4 or a custom designed application.
Networking and communication with a PC requires a docking station. Several models of docking stations are available with the following interfaces:
RS-232 (COM) port
USB port
Ethernet (TCP/IP)
When the number of available ports (COM, USB or Ethernet) is limited, up to 64 HygroLog NT can be connected together using a multi-dropped RS-485 network. In principle, an unlimited number of such networks can be used.
Example 1: Docking station with RS232 or USB port
The number of docking stations with RS-232 or USB port that can be directly connected to a PC depends on the number of physical COM ports and USB ports available on the PC.
Example 2: Ethernet docking station (RJ45 connector)
Our Ethernet compatible docking stations allow a substantial number of HygroLog NT to be centrally monitored by a single PC (up to 253 docking stations per LAN / sub-network). Due to current technological limitations, please note that the HygroLog NT should be not be used with the optional internal probe because of the heat generated by this type of docking station. Accurate measurements require a probe separated from the docking station and data logger by a length of cable.
Probe Adjustment
When equipped with the LC display and keypad, the HygroLog NT can be used to adjust any HygroClip probe connected either to the logger or to the docking station. Probe adjustment functions include the following:
1-point adjustment of humidity (offsets all measurements)
1-point adjustment of temperature (offsets all measurements)
Full adjustment of humidity (from 2 to 4 points)
Full adjustment of temperature (2-point)
The ROTRONIC HW4 software offers the same functions with the additional benefit that a probe adjustment protocol can be generated and printed.
Example of HW4 Probe Adjustment Protocol (also available in MS Word format):
Certified Humidity Standards: if you do not have access to a humidity generator, the ROTRONIC humidity standards offer a reliable and convenient way to generate a reference humidity condition during probe calibration. The ROTRONIC standards are shipped with an internationally accepted certificate, meeting in full the requirements of quality systems such as ISO9000. The standards are available in boxes of 5 glass ampoules of the same value, and can be stored indefinitely. Standards in the range of 5 to 95 %RH are non-saturated aqueous salt solutions. The 0 %RH humidity standard is made of small granules of a highly porous ceramic. A Material Safety Data Sheet is available for each standard.
Calibration Devices: a calibration device is a small airtight container that fits on the probe and seals around the humidity sensor. During calibration, a known reference humidity is produced inside the calibration device by means of a humidity standard.
