Conversions are true-rms responding and specified from 5 % to 100 % of range. Input signal crest factor can be up to 3 at full scale up to 500 V, decreasing linearly to crest factor < = 1.5 at 1000 V. For non-sinusoidal waveforms add ± (2 % reading + 2 % FS) typical, for a crest factor up to 3. Input impedance: 10 MΩ (nominal), < 100 pF, ac-coupled Common mode rejection ratio (1 kΩ unbalanced): > 60 dB at dc, 50 or 60 Hz Overload protection: 1000 V rms or dc, 107 V Hz Max DC voltage measurement Range 6.000 V dc 60.00 V dc 600.0 V dc 1000 V dc 1Accuracies apply to ± 100 % of range Resolution 0.001 V 0.01 V 0.1 V 1 V Accuracy 15871 0.09 % + 2 0.09 % + 2 0.09 % + 2 0.09 % + 2 Input impedance: 10 MΩ (nominal), < 100 pF Normal mode rejection ratio: > 60 dB @ 50 Hz or 60 Hz Common rode rejection ratio: > 120 dB @ dc, 50 Hz or 60 Hz (1 k unbalance) Overload protection: 1000 V rms or dc Accuracy 15771 0.2 % + 2 0.2 % + 2 0.2 % + 2 0.2 % + 2 DC millivolts measurement Range 600.0 mV dc Resolution 0.1 mV Accuracy 1587 0.1 % + 1 Accuracy 1577 0.2 % + 1 2 Fluke Corporation 1587/1577 Insulation Multimeters
