Diode Test
1. Connect the black test lead to the "COM" jack and the red test lead to the " " jack. (Note: The polarity
of the red lead is positive "+". )
2. Set the range switch to position.
3. Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode.
4. The display shows the approximate forward voltage of the diode. If the connection is reversed, "OL" will be shown on the display.
Measuring Insulation Resistance
Note
1. Before you perform insulation resistance test, make sure that the object to be tested is without power.
2. To avoid electric shock, be cautious. After you finish insulation resistance test, discharge the tested object fully.
3. To avoid electric shock, do not touch the object under test with your hand or skin, and do not touch any naked conductor of the meter
(including test leads) with your hand or skin.
Always place your fingers behind the finger guards on the test leads when using the probes.
4. Before test, make sure that the meter's fuse is good.
1. Test lead with a big test clip
2. High-voltage test lead
1. Refer to Figure 5 and the section of "Identifying Test Leads", insert the plug of the high-voltage test lead into "MΩ " jack, then
insert the plug of the test lead which has a big test clip into " " jack.
jack is a ground line. The test lead from "MΩ " jack is a live line. Set the rotary switch to OFF position, then
2. The test lead from "
connect the big test clip to the test point of the object to be measured.
3. Choose desired rated voltage: To choose the desired rated voltage, set the range switch to corresponding voltage position
( " ", " " or " " ).
4. Touch the probe of the high-voltage test lead to another test point of the object. Press TEST button, the display shows as an
indicator, the meter starts insulation resistance test, and high voltage is being outputted through the terminals. Read the reading on the
display. When the insulation resistance is less than 5MΩ, the built-in buzzer will sound.
