1.â Input impedance: 10 MΩ (nominal) in parallel with < 100 pF, with overload protection of 1000 V RMS
2.â Crest factor ⤠3. For non-sinusoidal waveforms with crest factor up to 3, add 2% reading + 2% full scale typical.
3.â Current can be measured from 50 mA to 440 mA continuously. An additional 0.2% needs to be added to the specified accuracy if the signal
measured is in the range of 440 mA to 1100 mA for 30 seconds maximum. After measuring a current of > 440 mA, leave the meter to cool
down for twice the measuring time used before application of low current measurement.
4.â Current can be measured from 0.5 A up to 10 A continuously with a maximum operating temperature of 50 °C. An additional 0.3% needs
to be added to the specified accuracy if the signal measured is in the range of 10 A to 19.999 A for 15 seconds maximum. After measuring a
current of >10 A, leave the meter to cool down for 60 seconds before applying a low current measurement.
5.â AC voltage and AC current specifications are AC coupled. True RMS measurement is valid from 5 % of range to 100 % of range.
