1. Turn off power to the circuit. Discharge all high-
voltage capacitors.
2. Turn the rotary switch to suitable range, press SELECT
to change from DC to AC measurement.
3. Insert the red test lead into the VΩmA or 10A terminal
and the black test lead into the COM terminal.
4. Set the rotary switch to an appropriate measurement
position in A range.
5. Break the current path to be tested. Connect the red
test lead to the more positive side of the break and the
black test lead to the more negative side of the break.
6. Turn on power to the circuit. The measured value
shows on the display.

Resistance Measurement

(Figure 5)
Warning
To avoid damages to the Meter or
to the devices under test, disconnect
circuit power and discharge all
the high-voltage capacitors before
measuring resistance.

The Ω ranges are : 400 Ω, 4 kΩ, 40 kΩ, 400 kΩ,
4 MΩ, and 40 MΩ
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 the Ω range.
3. Connect the test leads across with the object being
measured. The measured value shows on the display.
Note:
• The test leads can add 0.1 Ω
Figure 5
• For high-resistance measurement
to 0.3 Ω of error to resistance
measurement. To obtain precision
readings in low-resistance
measurement, that is the range
of 200 Ω, short-circuit the input
terminals beforehand and record
the reading obtained (called
this reading as X). (X) Is the
additional resistance from the
test lead. Then use the equation:
measured resistance value (Y) - (X)
= precision readings of resistance.
(>1MΩ), it is normal taking several
seconds to obtain a stable reading.
