Replaceable Parts and Operating Lifetimes
Useful life depends on the operating environment and frequency of use. Operation can-
not be guaranteed beyond the following periods.
For replacement parts, contact your dealer or Hioki representative.
Fuse
The fuse is housed in the power unit of the HiLogger. If the power does not turn on, the
fuse may be blown. If this occurs, a replacement or repair cannot be performed by cus-
tomers. Please contact your dealer or Hioki representative.
Cleaning
To clean the HiLogger, wipe it gently with a soft cloth moistened with water or mild deter-
gent. Never use solvents such as benzene, alcohol, acetone, ether, ketones, thinners or
gasoline, as they can deform and discolor the case. And, wipe the LCD gently with a soft,
dry cloth.
