I4
is valid only if the device is equipped with the I4 Input option, and
In (Calculated Neutral Current)
will automatically be used to if
the meter is equipped with the AI option (instead of I4).

Logical Module
The iMeter 6 comes standard with 6 user programmable Logical Modules which may be programmed to perform
an AND, NAND, OR or NOR logical operation. The Logical Module provides extensive control by allowing a user
to initiate an action based on the combinational logic of up to four different Setpoint conditions.
The Logical Modules can be programmed via the Web Interface or communications and have the following setup
parameters:
