Model UT60A: OPERATING MANUAL
Measurement Operation (10)
E. DC or AC Current Measurement
Warning
Never attempt an in-circuit current measurement
where the open-circuit voltage between the circuit
and ground is greater than 250V.
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.
The current measurement has 3 measurement positions
on the rotary switch: A
The A
auto ranging; the mA
range, with auto ranging; Hz
and 10.00A range, with auto ranging.
To measure current, do the following:
1.
Turn off power to the circuit. Discharge all high-
voltage capacitors.
2.
Insert the red test lead into the AmA or 10A or
terminal and the black test lead into the COM
terminal.
3.
Set the rotary switch to A
Use the 10A terminal and Hz
position if the current value to be tested is an
unknown.
