4) Press or lock “test” key⑩ to start the test. At this time HV
output indicator light above “test” key will glow and built-in buzzer
will sound per 1 second interval which indicating LINE terminal ②
having high-voltage output.
Warning: During test, it is forbidden to touch the front exposed
part of probe to avoid the risk of electric shock.
5) When the green LED glows, read insulation resistance value
on the upper scale (high range); red LED glows, read value on the
lower scale. After test, release “test” key ⑩, the instrument stop test,
wait for a few seconds, and do not immediately remove the probe
from test circuit. At this time the instrument will automatically
release the remaining charge in the test circuit.
Warning: When test is completed or repeatedly do tests,
measured target must be shorted, and then be grounded to
