Acceleration sensor
Connect a acceleration sensor to Model U8979 Charge Unit
Familiarize yourself with “Operation Precautions” (p. 8) before connecting a current sensor.
Acceleration sensor connectable with Model U8979
CAUTION
Use an acceleration sensor with a built-in pre-amplier that conforms to the specication
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-amplier BNC connector Drive power: 3.5 mA, 22 V

1
Align the slots in the BNC connector of an
acceleration sensor with the locking studs of a
BNC connector on the module, and insert the
connector.
2
Turn the BNC connector of the acceleration
sensor clockwise until it locks.
3
Attach the acceleration sensor with the built-in
pre-amplier to a measuring object.
How to connect the cable and a sensor
Turn the BNC connector of the acceleration
sensor counter-clockwise to release the lock
and remove the connector.
Connecting an acceleration sensor other than a sensor with a built-in pre-amplier
Convert the output connector into the BNC connector using a commercially available conversion
connector or conversion cable to connect the sensor.

Logic probe (Measuring logic signals)
Connect logic probes to Model 8973 Logic Unit.
Refer to “Before connecting a logic probe to a measuring object” (p. 17).
Refer to an instruction manual of each logic probe.
Required item: Logic probe (Model 9320-01, Model MR9321-01, or Model 9327)
How to connect a logic probe
Example: Connecting Model 9327 Logic Probe
Model 8973 Logic Unit
1
Align the plug slots of the logic probe with a
logic terminal, and insert the logic-probe plug.
2
Connect the logic probe to a measuring object.
Only slots to which UNIT 25, UNIT 26, or UNIT
27 is assigned are available.
