When measuring current with a 9018-50 Clamp On Probe
You can use a voltage measurement unit such as the 8966 Analog Unit to make measurements. For more
information about how to configure the instrument for use in this type of application, see the example settings
in "7.4.1 Scaling Setting Examples" (p.150).
Applicable Modules
• Model 8971 Current Unit
Use to connect: Clamps
• Model 9272-10
Clamp On Sensor
• Model 9709, CT6862, CT6863,
CT6865
AC/DC Current Sensor
• Model CT6841, CT6843,

• 8971 Current Unit cannot be used with
MR8741.
• With MR8740, up to four 8971 Current
Units can be used.
1
Align the grooves of the unit sensor
connector and the conversion cable
plug. Insert the plug until it locks.
2
Align the grooves of the conversion
cable connector and the plug of the
clamp-on sensor to be used. Insert
the plug until it locks.
3
Connect the clamp sensor to the item
to be measured.
To disconnect the conversion cable:
Slide the plug to release the lock and
then unplug the cable.

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

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.
