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'' }
