Pressure Connection To The Sensors
•
For measurements of over pressure (-10.0mbar...350.0mbar):
Connect plastic tube with internal dia of 4 mm to pressure port "+". Port "-" will not be used!
•
For measurements of under pressure (-350.0mbar...0.0mbar):
Plug the tube to pressure port "-". The measuring range covers then -350.0 to 0.0 mbar.
Note: All values are displayed now as positive values. No minus sign will be shown.
Example: it is possible to messure under pressure down to -350.0 mbar, the display shows then the
value 350.0 (no minus sign).
•
For measurements of pressure differences:
Connect both plastic tubes with an internal dia of 4 mm to pressure port "+" and "-"; make sure to apply
higher pressure to port "+".
Calibration Services
Calibration certificates – DKD-certificates – other certificates:
If device should be certificied for its accuracy, it is the best solution to return it with the refering sensors to
the manufacturer.
Only the manufacturer is capable to do efficient recalibration if necessary to get results of highest accuracy!
The Serial Interface
By means of the serial interface and a suitable electrically isolated interface adapter (GRS3100 or
GRS3105) the device can be connected to a computer for data transfer. With the GRS3105 up to 5 devices
of the MH3xxx- series can be connected to one interface (see also manual of GRS3100 or GRS3105)
To avoid transmission errors, there are several security checks implemented e.g. CRC.
The following standard software packages are available:
EBS9M
:
9-channel software to display the measuring values
EASYCONTROL
: Universal multi channel software (EASYBUS-, RS485-, or MH3000- operation
possible) for real-time recording and presentation of measuring data of one MH3xxx
device in the ACCESS®-data base format
In case you want to develop your own software we offer a
MH3000-development package
including:
•
a universally applicable Windows functions library ('MH3000.DLL') with documentation that can be used
by the most programming languages.
•
Programming examples Visual Basic 4.0, Testpoint (Keithley Windows measuring software)
Note:
The measuring and display range values read back from the interface are always in the
selected measurement unit (mbar, bar...)!
