Power-on confirmation
• Does the self-test (model and version)
display?
• When the self-test finishes, does the
[Wiring] page of the Setting or Mea-
surement screen appear (according to
when the instrument was last turned off)?
Contact your dealer or Hioki representative
if you find any damage.
The power cord may be damaged, or the
instrument may have internal damage.
Please contact your dealer or Hioki representative.
Connect the Cables and Sensors, and Power On
If damage is found.
If the self-test does not display, or
if an error is displayed.
Plug the other end of the
power cord into an outlet.
