The arrows on the
clamp indicating the
direction of current
flow should point to-
ward the load side.
OK
Clamp around only one conductor. Measure-
ment is not possible if the clamp is placed
around two lines in a single-phase circuit, or
three lines in a three-phase circuit.
Source
Clip securely to metal
parts
such as connection
screws or bus bars at the
secondary side (the load
side) of a breaker.
If you have difficulty clipping
screws, you may find it conve-
nient to use an optional mag-
net adapter (Model 9804-01,
Model 9804-02).

5. Connect the Voltage cords and the clamp sensors to the
line to be measured, while referring to the wiring diagram.
We recommend that the color of a voltage cord be matched to that of the
attached input-cord label used for the same channel.

According to the sensor,
the shape and position of
the arrow mark varies.
