● N1: The maximum verifi cation of current and frequency product is less than
400,000 A x Hz.
Notes:
1. The accuracy does not include the tolerance of thermocouple probe, and the
meter should be putting on the place will be operating for 1 hour at least.
2. Do not allow the temperature sensor to contact a surface that is energized
above 33 V RMS or 70 V DC. Such voltages will pose a shock hazard.
3. The temperature calculation is according to the standard of
EN/IEC-60548-1 and NIST175.
