LABDMM2
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).
