C. DC Current Measurement (see figure 4)
Warning
Never attempt an in-circuit current measurement
where the voltage between terminals and ground
is greater than 60V . If the fuse burns out during
measurement, the Meter may be damaged or the
operator himself may be hurt. Use proper terminals,
function, and range for the measurement. When
the testing leads are connected to the current
terminals, do not parallel them across any circuit.
Measurement Operation (4)
