DANGER
● Since a high voltage of 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, un-
expected 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.
CAUTION
● When using Test Leads with the crocodile clip, be sure to check the crocodile
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 500V. DC.
If this voltage seems too high for the appliance under test contact the
appliance manufacturer for advice. The IEE Code of Practice allows for a
touch current test where an insulation test cannot be carried out.
● 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.
