4 Pressure Connection To The Sensors
• For measurements of over pressure (-100 mbar ... 2000 mbar):
Connect plastic tube with internal dia of 4 mm to pressure port "+". Port "-" will not be used!
• For measurements of under pressure (-2000 mbar ... 0.0 mbar):
Plug the tube to pressure port "-". The measuring range covers then -2000 to 0 mbar.
Note: All values are displayed now as positive values. No minus sign will be shown.
Example: it is possible to measure under pressure down to -2000 mbar, the display shows then the value
2000 (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 "+".
5 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 referring sensors to
the manufacturer.
Only the manufacturer is capable to do efficient recalibration if necessary to get results of highest accuracy!
