List of
Replacement
Parts
Useful life depends on the operating environment and frequency of use. Opera-
tion cannot be guaranteed beyond the following periods. For replacement parts,
contact your dealer or Hioki representative.
Note: The service lives of these components may be shortened dramatically if
the instrument is used in a high-temperature environment.
• The fuse is housed in the power unit of the instrument. If the power does not
turn on, the fuse may be blown. If this occurs, a replacement or repair cannot
be performed by customers. Please contact your dealer or Hioki representa-
tive.
• The instrument contains a built-in backup lithium battery. If the date and time
deviate substantially when the instrument is switched on, it is the time to
replace that battery. Contact your dealer or Hioki representative.
To clean the instrument, wipe it gently with a soft cloth moistened with water or
mild detergent. Never use solvents such as benzene, alcohol, acetone, ether,
ketones, thinners or gasoline, as they can deform and discolor the case.
