PowerMonitor 1000 Unit Features
This section describes in detail the functions of the power monitor. Each
function includes information on set-up menus and parameters used to control its
operation.
Analog Input Setup This feature applies to all models.
Setup
The power monitor calculates metering results based on scaled voltage and current inputs. Setting
up the analog inputs is necessary to obtain accurate, properly scaled metering results.

PT primary The primary value of the PT ratio (Pri:Sec) indicating the
nominal voltage present at the high-end of the transformer.
For direct connect, set the PT ratio to any valid 1:1 ratio (for
example, 480:480).
