Electrical Specifications; Reference Conditions; Dc And Ac Currents - Chauvin Arnoux F27 Notice De Fonctionnement

the HOLD and COM symbols are displayed, triggering of the 1st transmission, COM flashes.
display of HOLD, emission of 2 validation beeps, the COM symbol flashes.
NB : In RECORD mode the process is identical to the normal mode with additional display of the PAUSE
symbol during the transmission.
4.21.3 C.A Transfer communication software
The C.A Transfer diskette contains the exploitation software under Windows which allows collection of the
data sent by the clamp and for the data to be saved in formats that can be directly exploited by the usual
spreadsheets.
For further information, please read the file "README.WRI".

5.1 REFERENCE CONDITIONS

The specifications are given in the following reference conditions :
- Temperature
- Relative humidity
- Battery voltage
- Position of the conductor
- Diameter of the conductor : ≤ 15 mm
- DC magnetic field
- External AC magnetic field : none
- External electrical field
- Frequency of the AC component of the signal : 45 Hz to 65 Hz
The accuracy is expressed as a % of the reading (± X% rdg) and in measurement counts (± count).
NB 1 : Unless contrary specification is given the response time of the display is 400 ms on "normal" mode and 3 s on
SMOOTH mode.
NB 2 : If applicable, particular reference conditions are specified with certain functions.

5.2 DC AND AC CURRENTS

Particular reference conditions :
- On AC : sinusoidal signal
- On DC : AC component ≤ 0.1% of the DC signal, with corrected zero
!
Limits on current measurements
- Operating frequency: 10 Hz to 5 kHz
- Permitted permanent overload: 2000 A (DC to 50 Hz)
- Temperature of clamped conductor: < 110°C
!
- NB : Display of
Triggering by long press on the "yellow" button :
Arriving at scan step, triggering of the transmission :
End of the transmission :
The HOLD symbol disappears,
the display again indicates the current values,
the COM symbol remains steadily displayed
the clamp is ready to emit at the next scan.
