[1] 20% over range on all ranges except ACV 750 V and ACI 10 A
[2] Specifications are for sine-wave inputs more than the 5% of range except 750 V range. Input signal must be more than
50 Vrms for 750 V range. Maximum crest factor of 3 at full scale. Input impedance is 1 MΩ in parallel with capacitance less
than 120 pF, AC couple with up to 400 DCV
[3] Additional error to be added as frequency > 30 kHz and signal input < 10% of range. 30 kHz to 100 kHz: 0.003% of full scale
per kHz
[4] For input < 200 V rms
[5] For input < 300 V rms
[6] Frequencies > 5 kHz are typical for all ranges
