Operating Procedure; Switching On; Dc Zero Adjustment; Measurement - Chauvin Arnoux PAC 10 Bedienungsanleitung

3.1/ SWITCHING ON

Set the sliding switch
Correct operation is indicated by a green light
is in good condition.
If this green indicator does not come on when the clamp is switched on,
or goes out during the operation of the clamp, it is necessary to replace the
battery (see MAINTENANCE chapter).
3.2/ ZERO ADJUSTMENT
Ensure that the jaws
enclose any conductor. Connect the clamp to your measurement instrument
set up according to the appropriate voltage range then turn the rotative button
until zero DC is displayed on the measurement instrument

3.3/ MEASUREMENT

After having switched on the clamp, connected it to the measurement
instrument on the appropriate range, and set the zero DC procedure (see
the two paragraphs above), clamp the conductor to be measured
between the jaws of the clamp.
The value is displayed on the measurement instrument.
Depending on the sensitivity selected on the clamp and the range of your
measurement instrument, apply the conversion ratio to get the value of the
current.
On DC current measurement, ensure that the arrow located on the
external edge of the jaws
current flowing in the conductor. (source Þ receiver)
