Adjustment Procedures

You can calibrate and adjust the MMT162 using Vaisala HUMICAP

hand-held moisture and temperature in oil meter MM70. See the

following sections:

- Calibration and Adjustment Using MM70 and a Reference Probe

below.

- Calibration and Adjustment Using MM70 and a Reference

Environment on page 58.

Connecting to the serial interface using a computer and a terminal

program allows you to perform calibration and adjustment tasks using

serial commands. See the following sections:

- Relative Humidity Adjustment on Serial Line on page 61.

- Temperature Adjustment on Serial Line on page 63.

For checking and/or clearing the currently applied calibration coefficients

on the serial line, see the following sections:

Calibration and Adjustment Using MM70 and a

Reference Probe

Required equipment:

- A fully charged MI70 indicator (the measurement display that is

included in the MM70 package)

- A calibrated MMP70 series probe (included with the MM70 hand-

held meter)

- Connection cable for MM70 hand-held meter (219980)

You can check and adjust the MMT162 using the MM70 hand-held

meter and a calibrated reference probe. You can perform this procedure

while the MMT162 is installed in oil if the environment is stable enough.

1. Plug in the connection cable 219980 to port II of the MMT162, and

the other end to port II of the MI70 indicator.

2. Connect the reference probe to port I of the MI70 indicator.

3. Insert the reference probe in the same environment as the

MMT162.
