You can adjust the transmitter's RH (HMD62) or T (HMD62 and
TMD62) measurement output with the trimmers on the component board. During trimmer
adjustment, the output of the transmitter is corrected using the trimmers until the output
matches the known value of a reference.
You can only calibrate the relative humidity measurement (RH) and temperature measurement
(T). Other parameters (available for HMD62) are calculated internally based on RH and T. Check that the output selection DIP switch is set to RH when making adjustments with the physical
trimmer; when using the Insight PC software, set all DIP switches to the OFF position.
CAUTION If you use the Insight PC software to adjust the measurement or to restore the factory settings, always return the physical
trimmer to the middle position before starting. When you make an adjustment with Insight, the position in which the trimmer is at that point is set as the ±0 point.
