Operating Procedure - Chauvin Arnoux C.A 41 Mode D'emploi

OPERATING PROCEDURE

Connect the measurement probe to the C.A 41 (probe EF1 or EF2). The connection is made
I
through the multicontact push-pull socket (1) located at the top of the instrument.
- Position the probe in the axis of the case,
- Turn the probe to align the locking system,
- Push the probe A in and push the ring B until it locks (clicks).
Switch on the instrument by turning the rotary switch (6) to select measurement with or
I
without alarm, as required (cf. chapter "USE").

I
As applicable, measure the radiation from a source of disturbance or the environnment
I
of a disturbed instrument. (B).
To do this, move the EF1 probe along the 3 perpendicular spatial axes (cf. chapter
I
"MEASUREMENT SENSOR") Fig.5. With probe EF2, simply point at the target to make
the measurement.
As the field diminishes proportionally with distance, take care to place the extremity
of the probe as close as possible to the zone to be checked.
The operator must take care not to be between the source of disturbance and the
zone to be checked: the human body shields electromagnetic fields.
