2.
the full-scale value will be calibrated and the HM35 returns to normal operation.
Notes
•
The calibration is always carried out in mbar.
•
The calibration must take place at a stable room temperature of 22 °C ± 2 °C.
•
A calibration value will only be accepted if it lies within ± 5 % of the full-scale
value of the HM35.
•
With the pressure connections open, it is possible to only re-calibrate the zero point.
•
The date of the last calibration will be stored in the Calibration History.
•
In case of manual re-calibration, the previous measurement will become invalid.
You should always carry out a complete accuracy check afterwards.
