makes firm contact with the bottom of the terminal. Measure and record the
terminal temperature in units of 1/100 °C. Do not convert this number to Fahrenheit,
even if the Meter is using the Fahrenheit scale for its display output.
Turn the rotary switch to the temperature position. It does not matter whether the Meter
is in calibration mode. On the Service Software menu screen, click
Enter the measured temperature value in the text box and click
recorded reference junction temperature to the Meter through the IR Serial Cable.
Although the temperature calibration is not yet complete, it is safe at this point to turn
the Meter off if the need arises. Doing so will not invalidate the previous steps.
To complete the temperature calibration, the DC mV function must be calibrated.
After DC mV calibration is complete:
1. Turn the rotary switch to the temperature position. Put the Meter in calibration mode
2. Press the
3. Continue calibrating the other functions, or turn the rotary switch to the

Re-Programming Serial Number or Model Number

When the U10 EEPROM is replaced, you must also reenter the serial number and model
number for the Meter. Do this as follows:
1. Connect the IR Serial Cable to the serial com port of the PC. Install 87/89-IV,
2. Turn the Meter rotary switch to any function.
3. On the Service Software menu screen, click
