Calibration Adjustments:

NOTE: Do not deviate from the calibration adjustment sequence

that follows. This will ensure that adjustments to be stored in

EEPROM go to the correct locations.

1. Perform meter-mode adjustments and verifications per Table 3 (use Table

5 for RTD-Thermistor models).

2. Hit OPR key (Flashing 'RTD' annunciator turns off).

3. Install J1 jumper.

4. Set unit to CALIB mode, RTD-100, °F.

5. Switch current source to OPERATE mode.

6 Perform calibrator-mode adjustments and verifications per Table 4 (use

Table 6 for RTD-Thermistor models).

7. Turn off unit. Remove tape holding battery.

8. Re-install back cover. Resistance-function calibration is complete.
