29. TEMPERATURE CALIBRATION
The pressure gauge has an internal temperature sensor with an accuracy of 1 ° C and a resolution of 0.1 ° C.
If the temperature reading does not fall within the specifications or if you want to improve this performance,
it is possible to calibrate the sensor.
Calibration of the temperature sensor is performed at two different temperature points.
The first point at room temperature (
t1 ) the second at a temperature of about 40 or 50 degrees ° C ( t2 ).
+
Press the keys simultaneously for a few seconds SET and PEAK.
P0000
Set the password 3126 (

) and confirm with SET.
t1
The message t1 will be displayed to indicate that the room temperature can be
calibrated.
Confirm with
SET .
25.3°C
The display shows the temperature read by the pressure gauge.
With a reference thermometer, measure the ambient temperature.
Correct the value displayed with the

keys until it is the same as the reference
measurement.
Confirm with
SET .
t2
The message t2 will be displayed to indicate that the second temperature point
can be calibrated.
Bring the pressure gauge to the desired temperature and wait until the system is
stabilized.
Confirm with
SET .
51.3 °C
The display shows the temperature read by the pressure gauge.
With a reference thermometer measure the temperature of the chamber.
Correct the value displayed with the
 keys until it is the same as the reference
measurement.
Confirm with
SET .
End
The procedure is complete.
In the event that problems should arise in the calibration procedure, it is possible to return to the factory
