4. Stop the output test voltage before removing the test leads (to enable the tester to
discharge capacitive circuits).
5. If the screen displays volts, wait until it reaches zero.
6. The meter displays the ">" symbol and the maximum resistance for the range when
measured resistance is higher than the maximum display range.

If the reading for DAR is bigger than 1.3 or PI is bigger than 2, it indicates a good
insulation quality.
When the measured resistance is higher than the maximum range, the screen will
display a "----" reading for the PI/DAR value.
