Measurement Operation (9)

Model UT33A: OPERATING MANUAL

Note

l The test leads can add 0.1Ω to 0.3Ω of 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

between the testing leads and the circuit under test.
