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.
