6-2 Calibration Procedure
6-2. Calibration procedure using air calibration
method
6-2-1. Preparation
Move the sensor to a maintenance site and wash
off any dirt on the membrane. Lightly wipe off any
remaining water from the membrane with a soft tis-
sue.
Expose the sensor to the air in an environment
where there is no temperature change and no wind
(a convenient way to accomplish this environment is
to place the sensor in an empty bucket).
Note:
If sensors are used without temperature
compensating element, the temperature
must be adjusted to ambient temperature in
service code 13.
