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.
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.
