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.

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.
