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’’ }
