Measurement Operation(7)
D.Resistance Measurement (see figure7)
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.
To avoid harms to you, never attempt to measure
voltages higher than 60V DC/30V AC.

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 VΩ terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to Ω .
3. Parallel connect the test leads across with the object
being measured.
4. The measured value shows on the display.
Note
l The LCD displays 1 indicating open-circuit for the
tested resistor or the resistor value is overload.
l The test leads can add 0.1Ωto 0.2Ω of error to
