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
