Current Measurements - Chauvin Arnoux E6N Notice De Fonctionnement

NB : for measurements of DC currents with low values (for example less than 5 A),
the accuracy will be improved if the zero reset is done before each measurement.
Zero reset is also advised if the current to be measured is very different from that
of the previous measurement. For example, after measurements of 100 A DC, we
advise resetting zero before measuring currents of around 10 amps. Zero reset is
also advised after changing the polarity of the current measured.

8.2 CURRENT MEASUREMENTS

- Place the switch of the clamp
on 100 A/V or 1 A/V. Check that
the light indicator is on.
- Connect the E6N clamp to a
Black Red
voltmeter on the 2 V AC or DC
range (black lead to common
and red lead to the «Volt» input).
- If necessary, reset zero (see
above).
- Enclose the jaws of the clamp
around the conductor carrying the current to be measured. Check that the
conductor is aligned in relation to the marks and that the clamp is fully closed.
