Pre-connection inspection

Voltage measurement cables

Does any cable insulation appear damaged, or
is bare metal exposed?

Current sensors

Is a clamp cracked or damaged?

Instrument

Is damage to the instrument evident?

Power-on confirmation

• Does the self-test (model and version)
display appear?

• 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

Please contact your dealer or Hioki repre­sentative.

If damage is found

If the self-test display does not
appear, or if an error is displayed

Connect the Cables and Sensors, and Power On

Verify that appropriate mea­surement values are displayed.

Verify that the vectors are dis­played with the appropriate
range, and that vectors are not
too short, or of unequal lengths.

When execute quick setup

Executing quick setup automatically config­ures the following settings to the Hioki-recom­mended values for the selected wiring mode
(phase system): voltage and current ranges,
sync source, lower measurement frequency
limit, integration mode, harmonic sync source
and rectification method.

Execute quick setup, and verify correct wiring
