Measurement Method
1
Turn off the power meter.
2
Affix the channel number stickers corresponding to
the power meter channels.
3
Remove the safety covers.
4
Connect the output cables to the power meter’s
current sensor input connectors.
5
Connect the measurement cables to the device’s
current input terminals.
6
Reattach the safety covers.
7
To prevent contact with the current input terminals,
secure the output cables for channels not being
used with a tie band.
8
Connect the measurement cables to the
measurement lines.
For more information about how to connect the device, refer
to the power meter’s instruction manual or the [Connection]
screen. If referring to the wiring diagram for a current sensor
or current probe, change the sensor in the wiring diagram so
that the connection is as follows:

When using the PW9100
To ensure accurate measurement, do not connect output
cables and measurement cables in parallel.
9
Apply the included color labels to the output cables
and wires as necessary so that channels and
connections can be identified.
10
Turn on the power meter and start measurement.
The device will be recognized as a 50 A rated current sensor
at each connected power meter channel.
The voltage must be measured in order to perform power
measurement. For more information about connections and
power meter settings and precautions, refer to the instruction
manual for the power meter being used.

Choosing the connection method
Example: When using the device and a PW6001 with a 1P2W
connection
Depending on the input level, the power meter’s instrument loss may
affect measured values. Choose the connection method that has the
lower instrument loss at the inputs connected to the load side from
the two possibilities shown below.
(1) Connecting the power
meter’s voltage input
terminals to the load side
Loss = (Input voltage [V])

(2) Connecting the device’s

Rack Installation
You can remove the screws from the rear of the
instrument and attach rack-mounting hardware.
The rack-mounting hardware shown at the right is
available on a special-order basis in both EIA and JIS
variants. For more information, please contact your
authorized Hioki distributor or reseller.
