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 reading + n digits'' }
