Note
The test leads can add 0.2Ω to 0.5Ω of error to resistance measurement. To
obtain precise readings in low-resistance measurement, short-circuit the
input terminals beforehand, using the relative measurement function button
REL to automatically subtract the value measured when the testing leads are
shortcircuited from the reading.
If Ω reading with shorted test leads is not ≤ 0.5Ω , check for loose test leads or
other reasons.
For high-resistance measurement (>1 MΩ), it is normal to take several seconds
to obtain a stable reading. To obtain stable reading, use a test lead as short as
possible or use the included multi-purpose socket to carry out measurement.
The LCD displays OL indicating open-circuit for the tested resistor or that the
resistor value is higher than the maximum range of the Meter.
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.
