Before you take a temperature measurement, momentarily change the
temperature of the thermocouple to verify a shorted or open thermocouple is
not incorrectly displaying the ambient temperature.
Helpful Tip: Increased Temperature Accuracy
To achieve high accuracy temperature measurements to ±1.0 °C it is necessary
to calibrate the meter to account for any thermocouple offset. Temperature
accuracy without performing the following calibration is ±3 °C:
1. Turn on the meter in the environment you will make the measurements.
2. Fill a wide, shallow container with ice and water. Stir the ice and water
mixture for two or three minutes to evenly distribute the temperature of
the mixture. Place the container next to the meter and submerge the tip of
the bead probe in the ice and water.
3. While in °C or °F mode, allow the temperature reading to stabilize on a
value (this value should be very close to 0 °C for °C mode or 32.0 °F for
°F mode). Any deviation from 0 °C or 32 °F represents the
thermocouple’s offset.
4. Once the reading stabilizes, press and hold softkey
