Notes:
1. The accuracy does not include the tolerance of the thermocouple probe, and the meter must be operational for at least one hour
2. Do not allow the temperature sensor to contact a surface that is energized above 33 V R.M.S. 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
