In order to avoid transmission errors, there are several security checks implemented (e.g CRC).
The following standard software packages are available for data transfer:
! EBS9M: 9-channel software to record and display the measuring values
! EASYCONTROL: Universal multi-channel software (EASYBUS-, RS485-, and/or GMH3000- operation possible)
for real-time recording and presentation of measuring data in the ACCESS®-data base format.
In case you want to develop your own software we offer a GMH3000-development package including
- a universally applicable 32bit Windows functions library ('GMH3000.DLL') with documentation that can be used by
all 'serious' programming languages.
- Programming examples Visual Basic 6.0™, Delphi 1.0™, Testpoint™, Labview™
Note: The measuring and range values read via interface are always in the selected
display unit (°C/°F)!
Supported interface functions:
Code Name/Function Code Name/Function
0 Read nominal value 201 Read max. display range
3 Read system status 202 Read unit of display
6 Read min. value 204 Read decimal point of display
7 Read max. value 208 Read channel count
12 Read ID-no. 216 Read offset correction
174 Delete min. value 217 Set offset correction
175 Delete max. value 218 Read corr. Factor (950..1200)
194 Set display unit 219 Set corr. factor (950..1200)
195 Set decimal point in display (255=Auto) 240 Reset
199 Read meas. type in display 254 Read program identification
200 Read min. display range
4.4.2 Analogue Output – Scaling with DAC.0 and DAC.1
With the DAC.0 and DAC.1 values the output can be rapidly scaled to Your efforts.
Keep in mind not to connect low-resistive loads to the output, otherwise the output value will be wrong and battery life is
decreased. Loads above ca 10kOhm are uncritical.
If the display exceeds the value set by DAC.1, then the device will apply 1V to the output
If the display falls below the value set by DAC.0, then the device will apply 0V to the output
In case of an error (Err.1, Err.2, SensErro, etc.) the device will apply slightly above 1V to the output.

5 Fault and System Messages
Display Meaning Remedy
low battery voltage, device will continue to work for a short time replace battery
If mains operation: wrong voltage replace power supply, if fault continues to
exist: device damaged
low battery voltage replace battery
If mains operation: wrong voltage Check/replace power supply, if fault continues
to exist: device damaged
low battery voltage replace battery
If mains operation: wrong voltage Check/replace power supply, if fault continues
to exist: device damaged
system error Disconnect battery or power supply, wait
some time, re-connect
No display
or
weird display
Device does not
react on keypress
device defective return to manufacturer for repair
Sensor error: no sensor connected Connect sensor to socketSenS
Erro
sensor/cable or device defective return to manufacturer for repair
Value exceeding measuring range Check: Is the value exceeding the measuring
range specified? ->temperature too high!
Err.1
sensor/cable defective -> replace
Value below display range
Check: Is the
value below the measuring
range specified? -> temperature too low
!
Err.2
sensor/cable defective -> replace
system error return to manufacturer for repairErr.7
Far out of allowable operation temperature -25..50°C are allowable
