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 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.

Note

l The test leads can add 0.1Ωto 0.3Ωof error to resistance measurement. To obtain

precision readings in low-resistance measurement, that is the range of 200Ω,

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.

l For high-resistance measurement (>1MΩ), it is normal taking several seconds

to obtain a stable reading.

l When resistance measurement has been completed, disconnect the connection
