AC Voltage Measurement

(Figure 3)
To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure voltages
higher than 500 V although readings may be obtained.
The AC voltage ranges are : 4 V, 40 V, 400
V and 500 V
1. Insert the red test lead into the VΩmA terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to V
3. Connect the test leads across with the object being
measured. The measured value shows on the display.
Note:
• DCV Measurement is autoranging, the Meter
has an input impedance of approx. 10MΩ. This
loading effect can cause measurement errors in
high impedance circuits.
If the circuit impedance is less than or equal to
10kΩ, the error is negligible (0.1% or less).

range.
• When DC voltage measurement has been
completed, disconnect the connection between
the testing leads and the circuit under test.

DC Current Measurement

(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.
To measure current, do the following:
1. Turn off power to the circuit. Discharge all
highvoltage capacitors.
2. Insert the red test lead into the VΩmA or 10A
terminal and the black test lead into the COM
terminal.
