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.
