2.4 Connecting the Measurement Cables, Probes, or
Fixture
Be sure to read the “Handling the cords, fixtures, and probes” (p. 14) before connecting mea
-
surement cables, probes or test fixture.
Connect your measurement cables, optional Hioki probes or test fixture to the measurement termi
-
nals. Refer to “Options (reference: open and short correction states)” (p. 2) for details. See the
instructions provided with the fixture for operating details.
Example: Hioki optional test fixture
Connect directly to the measurement jacks
with the label side up, and affix with the le

vers on the left and right.
Example: Hioki optional Model 9140-10
Connect the red plugs to the H
CUR
and H
POT
jacks, and the black plugs to the L
CUR
and L
POT
jacks.

Points to pay attention to when making your own probe
•Use 50
Ω
coaxial cable for the measurement cable.
•
When it ships from the factory, the instrument has been adjusted for the length of its cable. Since use
of a cable with a different capacitance value between the coaxial cable’s core wire and the shielding will
introduce a measurement error, use a cable whose capacitance value is as close as possible to that used
when adjusting the instrument prior to its shipment (1 m: 111 pF/cable; 2 m: 215 pF/cable; 4 m: 424 pF/
cable).
•
Make the portion of the core wire that is exposed as short as possible.
•Connect the H
CUR
, L
CUR
, H
POT
, and L
POT
shield pairs at the measurement sample side.
(Ensure that a shield is not connected to a core wire.)
•
probe yourself, it may not be able to satisfy the specifications of this instrument.
•
If all four terminals are disconnected, a meaningless number may be displayed on the unit.
