Single-Point Temperature Calibration (Procedure)
Refer to figure 22 during the single-point calibration procedure. Before starting the procedure, unlock and open
the Mini-AT's door. Locate connector J2 near the top center of the main circuit board.
1) Plug the Mercor Mini Field Calibrator cable onto the main circuit board connector J2. Make certain
all six pins are fully inserted into the black plastic cable connector. The cable connector is angled
to prevent the connector from being plugged in upside-down.
2) Use a mag wand to scroll to the Live Temperature display of the Meter Reader List.
3) While the temperature probe is inserted into the gas line's thermowell, record (write down) the Mini-
AT's live temperature reading.
4) Remove the temperature probe from the thermowell and insert the stem of the calibrated thermometer
into the thermowell.
