6. TECHNICAL SPECIFICATIONS
6.1. Genera
l
Only the values assigned tolerances or given limits are guaranteed values. Values without
tolerances are giv
en for information only, without guarantee (s
tandard NFC 42670). The
measurement errors must be considered in an env
ironment of reference temperature (refer to
§
6.2.11).
It is essential that all measuring instruments are regularly calibrated.
6.2. Characteristics
Accuracy is ± [% reading (R) + number of digits (D)].
{Accuracy : ‘’n %R + n D’’ means ‘’n % of the reading + n digits’’ }

Common mode rejection : at 50 and 60 Hz, better than 120 dB
Serial mode rejection : at 50 and 60 Hz, better than 60 dB
Intermittent signal sounds and « OL » on the display in case of range overpassing.
For measurements performed on alternative signals, the selected range must tally with the max.
value of the signal peak.
Additional error in Pk +/- mode for a pulse width of ≥ 1 ms : 1 % R ± 50 D
