GDUSB 1000
Universal interface adapter for
GMSD/GMxD-sensors
1 General
The GDUSB1000-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 GDUSB1000 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 GDUSB1000 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)

2 Safety regulations
This device was designed and tested considering the safety regulations for electronic measuring devices. Faultless operation and reliability in operation of the measuring device can only be assured if the
General Safety Measures and the devices specific safety regulation mentioned in this users manual are
considered.
1. Faultless operation and reliability in operation of the measuring device can only be assured if the
device is used within the climatic conditions specified in the chapter “Specification“.
2. By faulty handling of the interface adapter a damage of the device can not be excluded. Likewise a
damage of your attached device is possible. In such case we cannot assume any warranty.
The manufacturer will not assume any warranty for damages to other devices resulting by use of the
interface adapter.
3. Standard regulations for operation and safety for electrical, light and heavy current equipment have
to be observed, with particular attention paid to the national safety regulations (e.g. VDE 0100).
4. When connecting the device to other devices (e.g. the PC) the interconnection has to be designed
most thoroughly, as internal connections in third-party devices (e.g. connection of ground with protective earth) may lead to undesired voltage potentials.

5 Operating modes
After restart the adapter is in the standard-mode.
5.1 Standard - Mode
In this mode the GDUSB1000 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 adresses 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
BUS
The communication can occur with every standard software for the GMH3xxx or EASY
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,...
(e.g.
Note: for use the GDUSB1000 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: 1ms ... 10sec.; 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
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...2.500mbar 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:
diameter at the fitting "B”.
• For pressure difference measurements:
"A” and “B”, whereas the higher pressure has to be connected to the attachment “B”.
fix both flexible hoses with 4mm inner diameter at the fittings
fix the flexible hose with 4mm inner
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.
6.6 Advice for calibration service
Factory calibration certificate – DKD-certificate – ministerial certifications:
If the measuring device shall have a calibration certificate you have to send it inclusive the sensor to the
manufacturer. Just the manufacturer can check the factory settings and correct them if necessary
