- Press Enter twice to exit the procedure now, completing a

one-point adjustment only. The adjustment sequence ends

with the text OK. Continue to step 12.

10. Transfer the probe to the second temperature reference. Do not

disconnect the cable from the transmitter or the adjustment

sequence will be interrupted.

11. Wait for the temperature to stabilize. Type c and press Enter to

update the reading and verify that the reading has stabilized:

T : 54.1243 2. ref ? c

T : 54.1442 2. ref ?

12. When the reading is stable, enter the reference temperature after the

question mark and press Enter:

T : 55.1841 2. ref ? 55.1

13. The temperature adjustment is now complete. Enter the l

command to verify that the calibration coefficients for T have

Analog Output Adjustment

In the analog output calibration the analog output is forced to the

following values:

- Current output: 2 mA and 18 mA.

- Voltage output: 10 % and 90 % of the range.

Connect MMT162 to a calibrated current/voltage meter in order to

measure either current or voltage depending on the selected output type.

To calibrate analog output, see section Calibrate Analog Output on page

35.
