5. TECHNICAL SPECIFICATIONS
5.1. 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 § 5.2.10).
It is essential that all measuring instruments are regularly calibrated.
5.2. Characteristics
Accuracy is ± [% reading (R) + number of digits (D)].
{Accuracy : ‘’n % R + n D’’ means ‘’n % of the reading + n digits’’ }

or 750 Vrms with the same accuracy as with
the 600 V range. This multimetre can not be used on power distribution networks with a nominal
voltage higher than 600 Vrms.
Number of points : 5000
Range selection : automatic or manual for the 5 V, 50 V, 500 V, 1000 V ranges
Common mode rejection (500 mV range) : at 50 and 60 Hz, better than 120 dB
Serial mode rejection : at 50 and 60 Hz, better than 60 dB, in manual mode
Intermittent signal sounds and « OL » on the display in case of range overpassing.
