Note
The test leads and the Meter inside wire will bring
around 0.2 to 0.5 of error to resistance
measurement when measuring low resistance. To
obtain accurate readings in low-resistance, short-
circuit the test lead beforehand and record the reading
obtained, call this reading as X. Then use the equation:
measured resistance value (Y) – (X) = accurate
readings of resistance.
If reading with shorted test leads is not < 0.5 ,
check for loose test leads, incorrect function selection,
or any other reasons.
When measuring high resistance (>1M ), it is normal
to take several seconds to obtain a stable reading.
In order to obtain stable reading, choose shorter test
lead to carrying out measurement.
The LCD displays OL indicating open-circuit for the
tested resistor or the resistor value is higher than the
maximum range of the Meter.
Model UT803: OPERATING MANUAL
When resistance measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test, and remove the testing
leads away from the input terminals of the Meter.
