* Does not include accuracy of the thermocouple probe.
* Accuracy specification assumes surrounding temperature
stable to ± 1°C. For surrounding temperature changes of
± 5°C, rated accuracy applies after 2 hours.
Note : The AC+DC True RMS value might be over the
selected range since the AC signal may add on the DC level.
