Thank you for purchasing this HIOKI "9269 DC BIAS
CURRENT UNIT."
To get the maximum performance from the unit,
please read this manual first, and keep this at hand.

afety

This Instruction Manual provides information and
notes essential for operating this equipment in a
safe manner and for maintaining it in safe operating
condition. Before using this equipment, be sure to
carefully read the following safety notes.

performance ofthe equipment or to its
correct operation.

. Overview

The HIOKI 9269 DC BIAS CURRENT UNIT is an
optional unit, which can be connected between a
HIOKI LCR/Z HiTESTER and the fixture, to allow a
DC bias current to be applied to an inductor or
transductor.

. Connecting the DC Bias Current Unit

and Test Fixture

DC bias unit

Plug the fixture into the measurement terminals
(UNKNOWN) of the tester, with the product name up.
Fasten it in place with the left and right fixing levers.

Test fixture

Connect the test fixture (or measurement probe) to
the measurement terminals (UNKNOWN) of the
tester, so that the H and L terminals match.
For fixing sample, refer to the Instruction Manual of
the fixture.

External DC bias power supply

Make sure that the external DC bias power supply is
turned off, and then plug the cable into the external
DC bias apply terminals (BNC terminal) of the 9269
to connect.

NOTE

A separate external power supply for the DC bias
current is also required.

Fixture

. Measurement Method

For safety reason, follows the procedure carefully.
Before measurement, always read the notes on use.

Set the DC bias characteristics of the sample.
Gradually decrease the output current of the

external DC bias supply until it reaches 0 A.
Remove the sample from the fixture.

. Notes on Use

Be careful about the polarity when connecting
together, the sample to be tested, and the DC
bias current source.

It takes a little time for the DC current which is
being supplied to the sample under test to reach
the set current, so you should wait for a certain
stabilization time period before performing testing.

Be careful, because if you perform testing before
this stabilization time period has elapsed, the
results will not be reliable.

NOTE

This 9269 can be used only with the 3511, 3522,
3531, or 3532.

CAUTIO

• The maximum DC bias current which can be
supplied to the 9269 is 2 ADC. If a DC bias
current greater than this limit is supplied
continuously, the units may be damaged.

• Do not apply the DC bias current more than
rated current of sample. Doing so may damage
the sample and testers.

• Ιn order to avoid electric shock accident, be
absolutely sure not to touch the test terminals
while the DC bias current is being supplied to
them.

• Do not short circuit of the fixture with the DC
bias current still being supplied. Doing so may
damage the fixtures or cause a short circui
accident.

. Notes on Using the DC Bias Voltage

Unit

Be careful to avoid dropping the unit or subjecting
to other mechanical shock.

Do not use the unit in direct sunlight, dusty
conditions, or in the presence of corrosive gases.

If the unit has gotten seriously wet, oily, or dusty,
stop using it and send it for service at an approved
HIOKI service facility.

For using the tester to which the test fixture is
connected and fixture, refer to Instruction Manual
of them.

Gently wipe dirt with a soft cloth moistened with
a small amount of water.

When the DC bias unit is attached to the tester, be
careful not to put any weight on it. This could lead
to damage both to the tester and to the DC bias
unit.

To eliminate measurement errors due to the
internal circuit of the DC bias unit, before carrying
out measurement, always carry out open-circuit
compensation and short-circuit compensation.
Carry out the open-circuit compensation and
short-circuit compensation with the 9269 and
fixture (or measurement probe) connected, and
with the bias application cable not connected.
For details on compensation, refer to Instruction
Manuals of the tester and fixture.

Fix the sample in the fixture.
Set the output current of the external DC bias

supply to 0 A, then apply the current. Next,
increase the output current setting progressively
to reach the required setting.
