• This message will be dis-
played in the measured
value display area if one of
the terminals is found to be
disconnected, for example
due to a broken wire, after
measurement.
Check the connection of each
terminal.
See "2.4 Connecting the Mea-
surement Cables, Probes, or
Fixture" (p. 35).
• The sample has not been
secured properly in the mea-
surement cable, probe, or
xture.
Check the manner in which
the sample has been secured.
Check the wiring for wiring
breaks or poor contact.
See the probe or xture’s user
manual as well as"Contact
check function (detecting poor
contact with the sample during
4-terminal measurement)"
(p. 85).
• This message will also be
displayed when using the
instrument in an environment
characterized by a large
amount of noise.
Consider taking the following
measures:
• Use guarding.
See"Appx. 2 Measurement
of High Impedance Compo-
nents" (p. Appx.3).
• Implement anti-external
noise measures.
See"Appx. 4 Countermea-
sures Against Incorporation
of External Noise" (p. Appx.5).
• Separate the sample, mea-
surement cables, and instru-
ment from the source of the
noise (motor, inverter, electro-
magnetic switch, power line,
equipment generating sparks,
etc.) or perform the measure-
ment in a separate room.
• Plug the instrument into a
grounded outlet.
• Use a separate power sup-
ply from the device that is
generating the noise.
Fan motor error
• The fan motor has stopped
or is operating at low speed.
• Turn off the instrument and
verify that its air vents are
unobstructed and free of any
foreign material.
• If no issues are found, the
instrument needs to be
repaired. Contact your au-
thorized Hioki distributor or
reseller.
