The power measurement range is calculated from the voltage and current range.
Measurement uncertainty
The measurement uncertainty specification applies for the specified ranges, assuming the reading inside
the given limits. Beyond the limits the uncertainty is not specified. If not otherwise specified, the frequency
of all inputs is identical and in the range between 15 to 75Hz. The ambient temperature must be in the range
between 18 to 28°C. An additional error is to be calculated for ambient temperatures beyond this range.
Additional error for ambient temperatures outside the specified range:
+/- 0.01% rdg per degC.
