Temperature coefficient applies to rms and average readings. For frequencies above 100kHz, add 0.01% of reading/°C to temperature coefficient.
24
Specifications apply for sinewave input, AC + DC coupling, 1 power line cycle, autozero on, digital filter off, following 55-minute warm-up.
25
For 1% to 5% of range below 750V range, and for 1% to 7% of 750V range, add 0.01% of range uncertainty. For inputs from 200kHz to 2MHz, specifications
apply above 10% of range.
