TECHNICAL SPECIFICATIONS

5.1. General

Only the values assigned tolerances or the limits declared
constitute guaranteed values. The values without any
tolerance are given as indications.
The symbol is displayed when input signal exceeds
measuring limit in 40 A~ (MX 650), 40 and 400 A~ (MX 655),
resistance and continuity range.
In voltage, current and frequency range, this symbol will not be
shown even the read reach the measuring limit of :
750 VAC, 1000 VDC, 1000 AAC/DC, 10 Hz.

5.2. Characteristics

Accuracy is to within ± [% of the reading (L) + number of
counts (ct)] in the reference conditions indicated in the
appendix.
(MX 655) When measuring U rms and I rms, add ± 1% L
additional error margin, from 5% to 50% of the range for a
maximum peak factor of 6, and from 5% to 100% of the range
for a peak factor of between 1.4 and 3.
Over and above these limits, accuracy is not specified.
