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.

Parameter Description Range Default User

Setting

Voltage mode Should match the external electrical system and how it is

wired to the PowerMonitor voltage and current input

terminals. Refer to the wiring diagrams.

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).
