SPECIFICATIONS
Only those values assigned tolerances or limits are guaranteed values. Values without
tolerances are given for information only (French standard NF C 42-670).
{Accuracy : ‘’n% R + nD’’ means ‘’n% of the r n digits’’ as per IEC 485}

Range selection:
Automatic or manual for the 5 V, 50 V, 500 V,
1000 V ranges
Common mode rejection:
At 50 and 60 Hz, better than 120 dB
Serial mode rejection:
At 50 and 60 Hz, better than 60 dB
