DANGER
●
Since a high voltage 250V or 500V is being output continuously,
when measuring insulation resistance, the user may get an
electrical shock. Any capacitors in the appliance under test may
become charged during testing and may contain hazardous
voltages do not touch them.
●
When testing, always be sure to keep your fingers behind the
safety protective finger guard on the test leads.
●
Disconnect the Tester from the power supply when measurement
is finished.
●
Do not leave the Tester with connected to the power supply.
#
WARNING
●
Never open the instrument case – because dangerous voltages
are present. Only fully trained and competent electrical engineers
should open the case.
●
If abnormal conditions of any sort are noted (such as a faulty
display, unexpected readings, broken case, cracked test leads,
etc.) do not use the Tester and return it to your distributor for
inspection and repair.
●
Never attempt to use the Tester if the Tester or your hands are
wet.
●
Stop using the test lead if the outer jacket is damaged and the
inner white jacket is exposed.
#
CAUTION
●
When using Test Leads with the alligator clip, be sure to check
the alligator clip is firmly connected to the metal part of the
device under test. Otherwise, inaccurate measurements or
arcing at the contacts may occur.
●
The rated measuring voltage for the insulation test is 250V or
500V DC. If this voltage seems too high for the appliance
under test contact the appliance manufacturer for advice.
●
When testing a faulty appliance, it may trip the circuit breaker
of main power supply during test and may cause interruption of
service. Be careful when the same main power supply is used
for PCs.
●
We are not liable for loss of data on PC during testing with the
Tester. The appliance under test is powered on during most
tests, but please turn it to the OFF position after testing.
●
Use a very slightly damp cloth for cleaning the Tester. Do not
use abrasives or solvents.
