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}
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.
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 :
Range selection :
Common mode rejection : at 50 and 60 Hz, better than 120 dB
Serial mode rejection :
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.
