The accuracy is specified according to the following conditions:
• 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 prior to measurement.
• Use the Null function to reduce the thermal effect. Before using Null
function, set the meter to no ambient compensation mode ( is
indicated) and keep the thermocouple as close to the meter as possible.
Avoid contact with any surface that has a different temperature from the
ambient temperature.
• When measuring temperature with respect to any temperature calibrator,
try to set both the calibrator and meter with external reference (without
internal ambient compensation). If both calibrator and meter are set with
internal reference (with internal ambient compensation), there may be a
deviation between the readings of the calibrator and the meter, due to
differences in ambient compensation between the two devices.
