To learn more about the ION modules in your meter, refer to the ION Device
Templates at www.pwrm.com. ION Device Templates list all of the ION modules
available in the current version of your meter, and the total number of each
module. ION Device Templates also show the ranges or options available for each
module’s setup registers.

Basic Setup
Basic configuration of the meter is provided by the Power Meter module. The
Power Meter module is the main connection between the power system
measurements and all other ION modules in the device. This module reports the
values for all voltage, current and power measurements.

The Power Meter module’s setup registers describe details of the power system
being monitored. Many of the Power Meter module’s setup registers are
configured when the meter is initially put into service, although the device will not
operate properly until Volts mode and PT and CT ratios are set. Some registers
may need to be changed to refine the device’s operation.

may need to be changed to refine the device’s operation.
The functions of the setup registers in the Power Meter module are as follows:

The registers are typically set when the device is commissioned. Changing the values of these registers
while the device is in service is not recommended.

Once basic setup is performed (i.e. the PT/CT and Volts Mode settings), the meter
operates properly. Typically there is no need to make further changes to the Power
