Detailed Specifications
For all detailed specifications:
Accuracy is specified for 2 years after calibration, at operating temperatures of 18 °C to 28 °C, with relative humidity at 0 % to 80 %.
Accuracy specifications take the form of ±([% of Reading] + [Number of least-significant digits]). In the 4 ½-digit mode, multiply the number of
least-significant digits (counts) by 10.
AC Voltage
AC conversions are ac-coupled and valid from 3 % to 100 % of range.
