3. OPERATION
Before taking any measurements, ready the safety information section.
Always examine the instrument for Range, contamination (excessive
dirt, grease, etc.) and defects Examine the teat leads for cracks or
frayed insulation. If any abnormal conditions exist do not make
measurements.
3.1 PRECAUTIONS
1. Disconnect all power from the circuit under test when making
measurements. If any voltage is present in the test circuit an erroneous
reading will result.
2. When the test switch is pressed a high voltage is generated between
‘L’ and ‘E’ terminals. Do not touch any live parts in the circuit
during measurement.
3.2 INSULATION RESISTANCE MEASUREMENT
1. Connect red test lead to ‘L’ terminal
2. Connect black test lead to ‘E’ terminal
3. Short the red and black test lead and press the test switch, Zero MΩ
should be indicated on the display.
4. Connect the test leads to circuit under test and press test switch.
5. Display indicates the reading in MΩ, if insulation resistance is higher
than the instrument, ‘1’ or ‘-1’ is indicated.
4. MAINTENANCE
If there appears to be a malfunction during the operation of the meter.
The following steps should be performed in order to isolate the cause of
the problem.
1. Check the battery.
2. Review the operating instruments for possible mistakes in
operating procedure.
3. Inspect and test the Test Probes for a broken or intermittent
connection.
4.1 BATTERY REPLACEMENT
To prevent electrical shock hazard, disconnect the test leads before
removing the battery cover. Also ensure that the test switch is not
pressed.
1. Remove the cover of battery case at the rear.
2. Remove the old batteries from the meter and replace with new
batteries. Replace all the same time.
4.2 Power Adaptor
1. While Using Power Adaptor, Remove the battery for better Battery
life.
2. Use Adaptor with 9V, 1.5 A Rating
