Proper way to connect a BNC connector
When disconnecting the BNC connector, be sure to
release the lock before pulling off the connector.
Forcibly pulling the connector without releasing the
lock, or pulling on the cable, can damage the connector.

5 Connecting the clamp sensors to the measurement lines
When the measured value is shown as 0 A
The zero-display processing (which forces the display to
read “0 A” when the reading is 0.4% of the range) may
cause the display to read “0 A.” Try using a lower current
range as described in the following step.
See: Instruction manual “2.6 Turning the Power On/Off”
1
Check the wiring
diagram.
When using 9660 sensor
Clamp 1 conductor only.
Hint
Example: Zero-display processing
With the 500 A range
Display will read “0 A” when the measured
value is 2 A (0.4% of 500 A) or less.

6 Setting the current range
Select an appropriate range based on factors such as the rated load, operating state, and breaker rating. When the range is too low, an over-range event
will occur during measurement, preventing accurate measurement. When the
range is too high, the magnitude of the error component will increase, preventing accurate measurement. Set the current range based on your expectation
of the maximum load current that will flow during the measurement period.

If the available save time is shorter than the measurement period, the following methods can
be used to increase the available save time:
• Increase the save interval.
• If there is any unnecessary data on the SD memory card, delete it or reformat the card.
