1. All AC voltage and AC current ranges are specified from 5 % of range to 100 % of range.
2. Crest factor of
≤
3 at full scale up to 500 V, decreasing linearly to crest factor
≤
1.5 at 1000 V.
3. For non-sinusoidal waveforms, add -(2% reading + 2% full scale) typical, for crest factors up to 3.
4. In the 9999
µ
F range for measurements to 1000
µ
F, the measurement accuracy is 1.2 % + 2 for all models.
5. Amps input burden voltage (typical): 400 mA input 2 mV/mA, 10 A input 37 mV/A.
