Note: when measuring DC signals, accurate DC value is
possible only when the current probe is fixed at a certain
position, otherwise, the change of the position of the probe
will cause the DC drift. When measuring AC signals, users can
move the current probe.
4 Before connecting the current probe to circuit, open the test
clamp and clamp it onto the conductor as shown in the figure
below.
