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:
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
The communication can occur with every standard software for the GMH3xxx or
EASY
BUS
(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.
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 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 measure-
ment 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.
ment 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)
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 nec-
essary.
This mode is especially adapted for measuring very fast pressure changes (1000 per second)
For example: detecting pressure peaks at switching operations, ....
