Only assigned tolerance values or limits are guaranteed values. Non-
tolerance values are for information (NFC 42670 standard).
Please note: "n%L +nUR" means "n% of reading + n Representation Unit"
according to CEI 485).
Technical specifications are only guaranteed after a 30-minute warming up
period.
On this position, users can measure the rms value of AC voltage with its
direct component (no capacitive coupling) : "TRMS" measurement.

Specifications valid from 20 % to 100 % of F rate > 20 kHz
Influence of peak factor on V precision:
• 0.5 % for peak factor between 2 and 3
• 1 % for peak factor between 3 and 6
Rejection: Common mode > 60 dB to 50 Hz or 60 Hz according to selection
Automatic or manual rate selection.
On this position, users can measure a direct voltage value or the direct
component of alternating voltage (you must keep to the range
corresponding to the rms value, see Serial mode).
