p. 192, p. 201
These terminals are enabled when "Sensor" is selected in the "Curr Input Terminal" in the
setting menu. The type and serial number of the current sensor will be displayed in the option
data in the system setting screen.
* At present, no optional current sensors are available although they are to be released in the
future.
Automatic recognition of optional current sensors
This product automatically recognizes any optional current sensors connected to the EXT
CLAMP terminals when the power is turned on. If a current sensor is replaced or newly
connected with the POWER switch turned on, the current sensor cannot be automatically
recognized.
- Whenever a current sensor is replaced or newly connected with the POWER switch turned
on, the user should take an action to make this product recognize the sensor.
p. 87
- The operation to make this product recognize the current sensor (i.e., to press the "Update
Opt. Information" key) is performed in system setup.
- If any current sensor connected to this product has not been recognized, a dialog message
to prompt the operation to make the system recognize the current sensor (i.e., pressing the
"Update Opt. Information" key) will be presented when the "Curr Input Terminal" menu is
selected or when the test is started.
- If the power is turned on again after the current sensor is connected, the current sensors
connected will be automatically recognized.
