DANGER
●
Be extremely careful not to touch the tip of test probe or circuit under test
to avoid electrical shock during insulation resistance measurement as
high voltage is present on the tip of the test probe continuously.
●
Wipe the test probe with a soft cloth, if it is wet, and use it after it’s dry.
●
Never make measurements with the battery compartment cover
removed.
WARNING
●
Always disconnect power to the conductor under test before starting
insulation measurement. Do not attempt to make measurements on a
live conductor. Otherwise, it may damage the instrument.
●
Before starting insulation resistance measurement on PV array, turn
off the main switch and disconnect the array from the solar inverter.
●
Do not make measurement if any malfunction of PV array is suspected.
●
Select and use ordinary insulation resistance measurement function
when measuring a conductor with P-N short-circuited.
●
PV arrays generate dangerous voltages and current during the day.
Measures for work in high voltage environment should be taken and
appropriate protective gears must be used.
