• These items are displayed and the settings can be changed if a model with two CT
inputs is used.
• For the number of turns, set the number of turns of the CT connected to this
device divided by 100.
For example, if the number of CT turns is 400, set 4.
Note that, if 0 is set, 800 turns apply (same result as when 8 is set).
• The optional CTs, models QN206A and QN212A, have 800 turns, so set 8 for them.
• For the number of power wire loops, set the number of times that the power
wire passes through the hole in the CT.
For example, if the power wire passes through the hole of the CT twice as shown
below, set 2.
Note that, if 0 is set, 1 applies (same result as when 1 is set).
