TECHNICAL 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 reading + n digits'' as per IEC 485}

Number of points :
Range selection :
Common mode rejection : at 50 and 60 Hz, better than 120 dB
Serial mode rejection :
Additional error in Pk +/- mode for a pulse of ≥ 1 ms : 1% R ± 50 D
For measurements performed on alternative signals, the selected range must tally with the
max. value of the signal peak.
