TECHNICAL SPECIFICATIONS

Only those values assigned tolerances or limits are guaranteed values. Values without tolerances
are given for information only (French standard NF C 42-670).
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 reading + n digits'' as per IEC 485}
