1.â The specifications above is specified after 60 minutes of warm-up time.
2.â The accuracy does not include the tolerance of the thermocouple probe.
3.â Do not allow the temperature sensor to contact a surface that is energized above 30 Vrms or 60 V DC. Such voltages pose a shock hazard.
4.â The temperature calculation is specified according to the safety standards of EN/IEC-60548-1 and NIST175.

5.â Overload protection: 1000 Vrms for short circuits with < 0.3 A current.
6.â The accuracy for all ranges is specified based on a film capacitor or better, and after the Null function is used to subtract the test lead resistance and ther-
mal effect (by opening the test leads).
