safety barriers on the test leads.
● Be sure to remove the test leads from the main power supply
promptly after measurement. Do not leave them connected to the
main power supply for a long time.
WARNING

present. If a fault develops, return the instrument to your distributor
for inspection and repair.
● If the overheat symbol appears on the display ( ) disconnect the
instrument from the mains supply and allow to cool down.
● 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 repair.
● Never attempt to use the instrument if the instrument or your hand
is wet.

CAUTION
● For safety reasons only use accessories (test leads, probes,
cases, etc) designed to be used with this instrument and
recommended by KYORITSU. The use of other accessories is
prohibited as they are unlikely to have the correct safety features.
● During testing it is possible that there may be a momentary
degradation of the reading due to the presence of excessive
transients or discharges on the electrical system under test.
Should this be observed, the test must be repeated to obtain a
correct reading. If in doubt, contact your distributor.
● Use a damp cloth and detergent for cleaning the instrument. Do
not use abrasives or solvents.
