4.3.2 Setting the Reference
Ensure the output of the Signal Generator has been set to continuous (
Cont
). Check
that there is current flowing from the signal generator by noting the reading on the
screen. A zero current reading indicates an open circuit and will give faulty indication
subsequently.
Clip one of the current clamps around the positive voltage lead from the signal
generator with the arrow pointing in the direction of current flow; i.e. away from positive
as shown in Figure 4-9. The current clamp has large and small positions for large and
small cables and bus bars. Use the smaller position where possible to reduce
interference.
