5. 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).
The technical specifications are guaranteed only after 30 min warm-up period. Except special
indication, they are valid from 5 to 100 % of the range of measurement.
{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, 600 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
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.
