”Current range”
Choose a desired current range. While “Record” is set at the “Recording Tab” to record the power quality
events, “AUTO”* is not selectable. To enable auto-ranging at current range, select “Do not record” for “Event”
in the REC Item. Please refer to “VT/ CT ” (P. 54) in this manual for the detailed settings of power quality
events.
* Measurements according to IEC61000-4-30 Class S cannot be performed while “AUTO” is selected.
Move the blue highlight to “A Range”.
Show the pull-down menu.
Select a desired range.
Confirm.
Cancel.
”CT Ratio”
Set the proper CT ratio when CTs (current transformer) are installed in the measured system. The selected CT
ratio will be reflected to all the values measured during any current measurements. The details about CT are
described in “VT/CT” (P.54).
Selection
0.01 - 9999.99(1.00)
* Default value is highlighted in gray.
Move the blue highlight to “CT Ratio”.
Show the value entry window.*
Set the CT Ratio.
Confirm.
Cancel.
Sensor detection
Pressing the key detects and displays the model names of the connected sensors automatically.
However, if the connected sensors are not the ones that should be connected for the selected wiring system,
or sensor detection fails, an error message will appear and the values entered at “Clamp”, “A Range” and “CT
Ratio” will be cleared. The details about “Sensor detection” are described in “Sensor detection” (P.44).
* A pop-up appears and show the effective range.
