8.1 Serial Interface
By means of the serial interface and a suitable electrically isolated interface adapter (USB 3100, USB 3100 N,
GRS 3100 or GRS 3105) the device can be connected to a computer for data transfer.
With the GRS 3105 up to 5 devices of the GMH3xxx- series can be connected to one interface (see also
manual of GRS 3105). As a precondition the base addresses of all devices must not be identical, make sure
to configure the base addresses accordingly
(refer menu point “Adr.” in chapter 6).
To avoid transmission errors, there are several security checks implemented e.g. CRC.
The following standard software packages are available:

GMHKonfig : Software for a comfortable editing o
f the device (e.g. Material selection…)

EBS 20M / 60M : 20-/60-channel software to display the measuring values
In case you want to develop your own software we offer a development package including:

a universally applicable Windows functions library ('GMH3000.DLL') with documentation that can be
used by the most programming languages.
Suitable for Windows XP™, Windows Vista™, Windows 7™

Programming examples Visual Basic 4.0
™, Delphi 1.0™, Testpoint™
Note: The measuring and display range values read back from the interface are always in the
selected measurement unit (mbar, bar...)!

9 Input Adjustment
9.1 Zero Displacement Sensor ('OFFS')
A zero displacement can be carried out for the measured value:
value displayed = value measured - offset
Standard setting: 'off' = 0.0°, i.e. no zero displacement will be carried out. Together with the scale correction
(see below) this factor is mainly used to compensate for sensor deviations. Input is in the display unit.
9.2 Scale Correction Sensor ('SCAL')
The scale of the measuring can be influenced by this setting (factor is in %):
displayed value = measured value * (1+Scal/100)
Standard setting: 'off' =0.000, i.e. value is not corrected. Together with the zero displacement (see above)
this factor is mainly used to compensate for sensor deviations.
