The connection between the test line, the detector and the object under test must be
reliable.
Since component test heating will cause errors, it is recommended that the test time should
not exceed 30 seconds, and the interval between each test should be 30 seconds, the
measurement results will be more accurate.
The meter displays the OL symbol during the test, indicating that the resistance between the
two points under test exceeds the range. It is necessary to restart the meter and test again to
eliminate the fault caused by the over voltage protection. If the fault is caused by the over
voltage protection, it means that the resistance being measured is charged, and the
resistance to be measured should be cut off immediately, and the test should be performed
after restarting the meter. Or check whether the test line is in good contact. It may be an
open circuit between the two points being tested.
4. Resistance precision test
After power on, connect the wire as shown in the figure below to test the resistance value of the measured
resistance.
The following figure shows the example to
test the resistance value between the meter box and the ground and the lower line.
The following figure shows an example to test the resistance value of two metal connectors
