Measurement Operation(4)
C.Resistance Testing (see figure 5)
(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.
Never attempt an in-circuit current measurement
where the open circuit voltage between terminals
and ground is greater than 60V DC or 30V AC rms.
The resistance ranges are: 200.0Ω, 2.000kΩ, 20.00kΩ,
200.0kΩ, 2.000MΩand 20.00MΩ.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the Ω
terminal and the
black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement
position in Ω range.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
