SERVICE MENU – MPX CALIBRATION
SQ35
Menu - MPX CALIBRATION lets you correct any differences between the
pressure displayed and the pressure measured with a reference pressure
gauge.
The three counters displayed can be modied and represent:
- P+ pressure value correction at + 2.10 bar
- P0 pressure value correction at 0 bar
- P- pressure value correction at – 0.80 bar
In order to determine whether the pressure value displayed is accurate,
you will need to connect the pressure transducer to an external device
capable of reproducing the 3 control conditions:
- P+ positive pressure +2.10 bar
- P0 atmospheric pressure 0.00 bar
- P- negative pressure – 0.80 bar
The device must be equipped with a reference pressure gauge to allow a
comparison with the displayed pressure value.
The displayed value can be changed in 0.001 bar steps.
