CHAPTER 9
CALIBRATION AND ADJUSTMENT OF
TRANSMITTERS
HM70 in Checking and Adjusting
The following transmitters can be calibrated by using HM70: HMDW
60/70, HMW 61/71, HMD/W 20/30, HMP130, HMP230/240 series,
HMT320/330 series, HMM210 series and DMW19 transmitter.
When calibrating in the field, check and adjust a fixed transmitter's
reading against a calibrated reference probe on the HM70.
One or two point calibrations can be done to industrial transmitters
and modules (HMP230/240 series, HMT320/330 series, HMM210
modules) by using a MI70 indicator and Vaisala's humidity calibrator
HMK15.
Calibration Cables
For calibration and adjustment connect HM70 to fixed transmitter by
using one of the following connection cables:
- HMA6070-cable for HMD/W 60/70 and HMW 61/71 transmitters
- HMA2030-cable for HMD/W 20/30 and HMP130 transmitters
- 27159ZZ-cable for HMP230/240 series transmitters and HMM210
series modules.
- 211339-cable for HMT320/330 series transmitters
- 211917ZZ-cable for DMW19 transmitter.
