6. TECHNICAL SPECIFICATIONS
6.1. General
Only the values assigned tolerances or given limits are guaranteed values. Values without
tolerances are given for information only, without guarantee (standard NFC 42670). The
measurement errors must be considered in an environment 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 r n digits’’ }

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
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.
