Ac Current Measurement - UNI-T UT60H Operating Manual

Model UT60H: OPERATING MANUAL
Measurement Operation(4)
Note
l If the value to be measured is unknown, use the
maximum measurement position and reduce the
range step by step until a satisfactory reading is
obtained.
l When the measured current is
measurement is allowed.
l When the measured current is between 5A-10A,
continuous measurement
more than 15 minutes.
l When DC current measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove testing leads
away from the input terminals of the Meter.
D. AC Current Measurement (see figure 4)
Warning
Never attempt an in-circuit current measurement
where the open circuit voltage between terminals
and ground is greater than 60V DC or 30V rms.
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.
Before the Meter is connected in serial to the in-circuit
being tested, turn off the power of the in-circuit..
