From this screen, it is possible to check/edit the typical value
of PT1 probe detected at 130.4°C.
This value is indicated directly on PT1 probe.
If the PT1 probe is replaced, proceed as follows:
- note typical reading of new probe
if necessary, change the reading using the
commands indicated on the left.
The system allows a maximum variation range of +/- 10 ohm
with respect to a nominal reading of 1500 ohm at 130.4°C.
It is also possible to CALIBRATE THE PRESSURE
SENSOR, correcting any differences between the pressure
value displayed and the pressure measured with a reference
pressure gauge.
The three counters displayed can be modified 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.
