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.
