Input element 760901 or 760902
Input element 760903
Turns scaling on or off
When you want to multiply the external current sensor output by
the conversion ratio and read the current of the circuit under
measurement directly, turn the VT/CT scaling feature off. If it is
turned on, the value will be further multiplied by the CT ratio.
Set the VT ratio (0.0001 to 99999.9999).
Set the CT ratio (0.0001 to 99999.9999).
Set the power coefficient (scaling factor)
(0.0001 to 99999.9999).
Set the CT ratio preset (CT2000A, CT1000A,
CT1000, CT200, CT60, Others).
Set this when using the dedicated CT.
