Acceleration sensor connectable with Model U8979
Measuring acceleration
Connect a acceleration sensor to Model U8979 Charge Unit.
Familiarize yourself with "Handling the Instrument and Modules" ( p.9) before connecting a current sensor.
Applicable Modules
• Model U8979 Charge Unit
The following device can be connected to the module.
• Acceleration sensor (Not available from Hioki)
Use an acceleration sensor with a built-in pre-amplifier that conforms to the
specification of Model U8979 Charge Unit. Using an inapplicable sensor may
cause damaging itself.
Acceleration sensor type Terminal the sensor is connected
to
Note
With a built-in pre-amplifier BNC connector Drive power: 3.5 mA, 22 V
Charge output Miniature connector (#10-32) –
1
Align the slots in the BNC connector
of anacceleration sensor with the
locking studs of a BNC connector on
the module, and insert the connector.
2
Turn the BNC connector of the accel-
eration sensor clockwise until it locks.
3
Attach the acceleration sensor with
the built-in pre-amplifier to a measure-
ment target.

Connecting an acceleration sensor other than a sensor with a built-in pre-amplifier
Convert the output connector into the BNC connector using a commercially available conversion con-
nector or conversion cable to connect the sensor.
How to remove the acceleration sensor
Turn the BNC connector of the acceleration
sensor counter-clockwise to release the lock
and remove the connector.
