Configure the Amp Meter to Use a CT
You can either use the APM configuration software, or the DIP switches on the rear of the APM.
Using the APM Configuration Software
- Make sure that all the DIP switches are in the OFF position (to the left pointing away from the screw terminals).
- Under ‘External Sensors’ select ‘CT’.
- Enter the primary (input) and secondary (output) currents of your CT. In the example below the CT has an input of 300A and an output of 5A (i.e.: 300:5).
Using DIP Switches
The table below shows the various switch positions. Lines 5-16 are for use with external 5 amp CTs.
