Default Meter Functionality
The following sections describe the default functionality defined by your meter’s
framework. With each advancement of firmware, there are changes to the
framework, so your meter operation may differ slightly from what is presented.
The ION Device Templates documentation lists all the ION modules available in the
current version of your meter, lists the total number of each ION module, and
shows the ranges or options available for each module’s setup registers. The ION
Devices Templates documentation is available at www.pwrm.com.
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 cannot
operate properly until the Volts Mode and PT and CT ratios are set. Some registers
may need to be changed to refine the device’s operation.
1 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.
