5. TECHNICAL SPECIFICATIONS
Only those values assigned tolerances or limits are guaranteed values. Values without
tolerances are given for information only (French standard NFC 42-670).
{Accuracy : ‘’n% R + nD’’ means ‘’n% of the reading + n digits’’ as per IEC 485}
Note If voltage measurements are out of the specifications or if other
measurements are no longer possible, first check the F2 fuse.
(See §. 3.5.1. Fuse self-test).

Number of counts : 50 000 (or 5 000 - refer to §. 3.4.)
Range selection : automatic or manual for the 5 V, 50 V, 500 V, 600 V ranges
Common mode rejection : at 50 and 60 Hz, better than 120 dB
Serial mode rejection : at 50 and 60 Hz, better than 60 dB
Additional error in PK+/- mode for a pulse of ≥ 1 ms : 1% R ± 50 D
For measurements performed on alternative signals, the selected range must tally with the
max. value of the signal peak.

(♦)
When the measurement terminals are connected to an intrinsically safe circuit,
the electrical specifications of intrinsically safe circuits must conform following
values : U ≤
≤≤
≤ 60 V (peak value) or I ≤
≤≤
≤ 500 mA.
After a use on circuits other than those of intrinsic safety, the user must observe
a period of 3 minutes waiting before carrying the multimeter in a dangerous area
of EX class.
