TECHNICAL
SPECIFICATIONS
Only those values assigned tolerances or limits are guaranteed values. Values without
tolerances are given for information only (French standard NFC 42670).
The technical specifications are guaranteed only after 30 min warm-up period. Except special
indication, they are valid from 5 to 100 % of the range of measurement.
{Accuracy : ‘’n%R + nD’’ means ‘’n% of the r n digits’’ as per IEC 485}
