Note
The test leads can add 0.1 to 0.2 of error to resistance measurement. To obtain
precision readings in low-resistance measurement, it is necessary to subtract the
value measured when the testing leads are short circuited from the reading.
If reading with shorted test leads is not less than 0.5 , check for loose test leads,
incorrect function selection, or any other reasons.
The LCD displays OL indicating open-circuit or the tested resistor or the resistor
value is higher than the maximum range of the Meter.
For high-resistance measurement (>1M ), it is normal to take several seconds to
obtain a stable reading.. In order to obtain stable reading, try to use as short as
test lead possible.
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.
