1. The accuracy does not include the tolerance of the thermocouple probe. The thermal sensor plugged into the meter should be placed in the operating
environment for at least an hour.
2. Use the Null function to reduce the thermal effect. Before using the Null function, set the meter to no ambient compensation (0C) mode and keep the
thermocouple probe as close to the meter as possible, avoiding contact with any surface that has a different temperature from the ambient temperature.
3. When measuring temperature with respect to any temperature calibrator, try to set both the calibrator and the meter with an external reference (without
internal ambient compensation). If both the calibrator and the meter are set with internal reference (with internal ambient compensation), deviation may
show between the readings of the calibrator and the meter, due to differences in ambient compensation between the calibrator and the meter.
