Measurement Operation (9)

1. Insert the red test lead into the V mA terminal and the black test lead into the
COM terminal.
2. Set the rotary switch to an appropriate measurement position in
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 0.1 to 0.3 of error to resistance measurement. To obtain
precision readings in low-resistance measurement, that is the range of 200 ,
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 (>1M ), it is normal taking several seconds
to obtain a stable reading.

When resistance measurement has been completed, disconnect the connection
