Coil TC Calibration

The CAT-100 contains a thermistor used to measure ambient temperature in the area near the binding posts to which the steel wire coil is attached for carbon analysis. This thermistor must be calibrated annually.

To calibrate, first press the Coil TC Calibration button. Using a digital thermometer with accuracy of ±0.1°C (±0.18°F), measure the ambient temperature within ¼” of the thermistor (see Figure 32). Enter this value in the Coil TC Calibration screen (Figure 40). The “Coil Temp” value will change to the value you entered.
