B. THEMOCOUPLE MEASUREMENT (K, J, T, E, R)
1. With the meter on, press the SENSOR button (3) to select your sensor
type. The display shows: IR, Pt3850, K, J,T, E, or R.
2. Insert the probe plug into the Thermocouple Input (11).
3. Press the °C/°F button (7) to select the temperature scale.
4. The LCD will display the temperature reading.
5. If needed, follow the Calibration Procedures on page 4.
NOTES
• Match the plug's polarity to the unit's polarity.
• To obtain the most accurate reading, the plug must stabilize at the
temperature of the socket. This will take a few minutes and only
applies if the probe plug has been exposed to an ambient temperature
different to that of the thermometer.
C. PT 100 OHM MEASUREMENT
