# DANGER
• This instrument can be connected only to the commercial power of
240V+10%-10%, 50Hz.
• For safety reasons, only use the Test Leads designed to be used with
this instrument and recommended by KYORITSU.
• Use only grounded mains outlets to supply the instrument.
Do not touch the device under test while testing is in progress.
• Since a high voltage of 500V is outputting continuously, especially while
measuring insulation resistance, user may get electrical shock. Also not to
touch the capacitor of the device under test as hazardous voltage may exist.
• When testing, always be sure to keep your fingers behind the safety
barriers on the test leads.
• Disconnect the instrument from the power supply when measurement
is finished.
• Do not leave the instrument 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 instrument and return it to your distributor for inspection and repair.
• Never attempt to use the instrument if the instrument or your hand is wet.
# CAUTION
• When using Test Leads with alligator clip, be sure to check the alligator
clip is firmly connected to the metal part of the device under test.
Otherwise, inaccurate measurement or arc at the contacts may occurs.
• The rated measuring voltage for insulation test is 500V.DC.
For electrical devices to be tested, if this test voltage seems not
proper to apply, contact your distributor and ask for advices.
• When testing faulty device, 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 this
instrument. The device under test (DUT) is powered on during most
tests, but please turn it to OFF position after use.
• Use a cloth dipped in water or neutral detergent for cleaning the
instrument. Do not use abrasives or solvents.
