1. Intended use
The GDUSB 1000-adaptor makes it possible to connect a standard pressure sensor of the type GMSD/GMXD directly to the USB-port of a personal computer. Two operation modes are available:
Standard-mode: (Master-Slave) In this mode the GDUSB 1000 acts like a portable measuring instrument of the GMH3xxx-series and gives back the wanted measurement on request (measurand, maximum or minimum data).
The communication can occur with the standard GMH/EASYBUS-software (e.g. EBS9M) and offers the possibility to monitor long-run measurements of pressure for example.
Fast-mode: (autom. sending) In this operating mode after a fulfilled trigger condition the GDUSB 1000 sends the measuring data automatically in the adjusted cycle time.
This mode is especially adapted for the analysis of pressure curves and the survey of pressure peaks (with pre-trigger)

page 4 of 8
5.1 Standard - Mode
In this mode the GDUSB 1000 acts like a portable measuring instrument of the GMH3xxx-series. It gives back the wanted measurement on request.
For this purpose 4 measuring channels are allocated at the addresses 1 4:
1 Measurand: with adjustable low-pass filter (0.00 ... 10.00)
2 Average:
the average between two measuring-points
3 Minimal peak: lowest measurand for the last request; unfiltrated, with highest sample rate
4 Maximal peak: highest measurand for the last request; unfiltrated, with highest sample rate
The communication can occur with every standard software for the GMH3xxx or EASYBus (e.g. EBS9M, ...) and offers the possibility to monitor long-run measurements of pressure for example.
For the integration in your own programs, we offer you the function-library EASYBUS.DLL. This operating mode is especially adapted for the measuring of 1 measurand per second. For example: long-run measurements of pressure, leakage test, ...
Note: for use the GDUSB 1000 you must select in the software the interface USB3100.
5.2 Fast - Mode
The device can be set to the mode "fast measurand display" via command. In this mode the measurement is started by a trigger condition. Then the device automatically gives back the measurands in the adjusted cycle time without any request, until the stop condition is fulfilled.
Adjustable parameters are among other ones:
Cycle time:
1 ms ... 10 sec., programmable in steps of ms
Measuring channel: cycle < 5 ms it is possible to choose the recording channel (measurand, min. peak, max. peak).
cycle > 5 ms all four measuring channels are recorded automatically
Trigger conditions:
5 for the measuring start 6 for the measuring stop
Pre-trigger :
50 data sets (at a cycle time of 5ms) respectively 200 measurands (cycle time < 5 ms)
For the communication and configuration of the device in this mode the software GSOFT-USB is necessary.
This mode is especially adapted for measuring very fast pressure changes (1000 per second). For example: detecting pressure peaks at switching operations, ...

6. General handling instructions
page 5 of 8
6.1 To connect/change sensors Only sensors of the GMSD or GMXD-serial are allowed to be used! If other sensors are used the adapter and the sensor may be destroyed. To change the sensor you have to disconnect the adapter. Sensors have to be connected before activating the adapter. Otherwise they are not found by the adapter correctly. During the connecting it is possible that the connector does not snap in the jack correctly. In this case you have to hold the connector at the anti-kink device not at the casing. Don`t plug the connector wedged. An accurate attached jack can be easily plugged in without great effort. To disconnect the sensors it is not allowed to pull at the cable. In this case you have to hold the connector at its casing.
6.2 Altitude correction of the absolute pressure sensor The device measures the absolute pressure of the ambient air. But this pressure is not to be confused with the "pressure at sea level", which is quoted by meteorological stations! At this indication the decrease of the air pressure which is dependent on the level will be calculated. The device has the ability to do this air pressure height adjustment. Activate for this the "sea level function" via the configuration software (GSOFT_USB) and specify the height beyond the sea level of your habitation.
6.3 Zero correction of the pressure sensor ('OFFS') For the measurement a zero offset can be conducted:
shown vale = measured value - offset The zero correction in combination with the slope correction (see below) are mainly used to adjust the deviation of sensors. The entry has to be made in the configuration software. The offset information will be stored in the sensor. So you can set it individually for each sensor.
6.4 Slope correction of the pressure sensor ('SCAL') The measurement`s slope can be affected by this factor (factor in %):
shown value = measured value * (1 + scale / 100) The slope correction in combination with the zero correction (see above) are mainly used to adjust the deviation of sensors. The entry has to be made in the configuration software. The scale information will be stored in the sensor. So you can set it individually for each sensor.
6.5 Pressure connection to the pressure sensor The measuring adapter is conceived that way that all sensors of the GMSD/GMXD...-series can be connected without new calibration. Therefore a multiplicity of fully exchangeable sensors for metering ranges of 1.999...2.500 mbar relative to 0...400.0 bar absolute for example are available.
Relative pressure sensors (type: GMSD/GMXD...MR, GMSD/GMXD...BR)
For overpressure and respectively low-pressure measurements: fix the flexible hose with 4mm inner diameter at the fitting "B". For pressure difference measurements: fix both flexible hoses with 4mm inner diameter at the fittings "A" and "B", whereas the higher pressure has to be connected to the attachment "B".
Absolute pressure sensors (type: GMSD/GMXD...BA) Fix the flexible hose with 4mm inner diameter to the fitting "A" ("B" is without any function).
Stainless steel sensors (type: GMSD/GMXD...MRE, GMSD/GMXD...BRE, GMSD/GMXD...BAE) For overpressure, low-pressure or absolute pressure measurements: screw the sensor in the winding (G1/4") or connect a flexible hose with an appropriate adapter to the pressure sensor.
