Notes on specifications:
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

Notes on specifications:
1.  The frequency can be measured up to 1 MHz as 0.5 V signal to 100 mV/1 V ranges.
2.  10% of range to full scale input on all ranges except where noted. 100 mV range specifications are for full scale or greater inputs.
For inputs from 10 mV to 100 mV, multiply total % of reading error by 10.
3.  10% of range to full scale input on all ranges except where noted. 10 mA range specifications are for full scale or greater inputs.
For inputs from 1 mA to 10 mA, multiply total % of reading error by 10.
