1. Set the range selection switch to 500 V.
2. Connect the black lead wire to the ground terminal.
3. Connect the red lead wire to the line terminal.
4. Connect the black lead wire (crocodile clip) to c in
order to measure the insulation resistance (1) (between
a and c) in the diagram below.
5. Next, insert the probe of the red lead wire into a.
6. Set the measure switch to LOCK, and then measure the
insulation resistance after 1 minute.
7. Check that the insulation resistance after 1 minute is
10 MΩ or more.
8. Next, measure the insulation resistance at (2) (between
b and c) in the diagram below in the same way as for
(1).
9. Check that the insulation resistance at (2) after 1 minute
is 10 MΩ or more.
