Notes for temperature specifications:
1 The specifications above is specified after 60 minutes of warm-up time.
2 The accuracy does not include the tolerance of the thermocouple probe.
3 Do not allow the temperature sensor to contact a surface that is energized above 30 V
RMS or 60 VDC. Such voltages poses
a shock hazard.
4 Ensure that the ambient temperature is stable within ±1 ºC and that the Null function is used to reduce the test lead’s
thermal effect and temperature offset. Before using Null function, set the multimeter to measure temperature without
ambient compensation ( ) and keep the thermocouple probe as close to the multimeter as possible (avoid contact
with any surface that has a different temperature from the ambient temperature).
5 When measuring temperature with respect to any temperature calibrator, try to set both the calibrator and multimeter
with an external reference (without internal ambient compensation). If both the calibrator and multimeter are set with
internal reference (with internal ambient compensation), some deviations may show between the readings of the
calibrator and multimeter, due to differences in ambient compensation between the calibrator and multimeter. Keeping
the multimeter close to the output terminal of calibrator will help reduce the deviation.
6 The temperature calculation is specified according to the safety standards of EN/IEC-60548-1 and NIST175.
