4. Operation
1). To make a current measurement,switch on the clamp
by selecting the 100mV/A range.Check that the battery
indicator(green)is lit and that the <<OL>>indicator is
not lit
2). Connect the clamp to the oscilloscope
With the clamp closed and without clamping a
conductor,select the highest sensitivity(for example
1mV/cm)on the oscilloscope and 100mV/A on the
clamp ,then set zero on the clamp with the thumbwheel
in
relation to
a
reference chosen on
the
oscilloscope.Zero on the oscilloscope makes it possible
to adjust this setting.
3). Select the measurement sensitivities of the clamp and
the oscilloscope
4). Choose the connection method which is the best
adapted to measurement on the oscilloscope
5). Note the direction of the primary current by means of
