Front Panel

The front panel contains the following indicators and controls:

 Three rows of alphanumeric displays, four digits each, display three RMS

parameters simultaneously or one energy parameter. The displayed

readings update every second.

 For each row: Kilo, Mega (Kilo + Mega = Giga) indicator, and a Negative

(-) indicator.

 Load bar, which gives a unique analog indication of % loading (% FS CT

Pri).

 Five keys to scroll through the display page.

Eight-segment LED display

 The power meter solves the problem of tiny cluttered indicators by

prominently displaying the parameter name right on the large,

alphanumeric readouts.

 For the first time in a panel meter, the parameter name is as clearly

readable as the value.

 In order to know which parameter value is currently displayed, the power

meter displays the parameter name for two seconds, as well as each time

you press a key, and then the value for eight seconds.

 This method also allows programmable phase soft-Labels in the power

meters. You can choose from 123 (factory setting), ABC, RYB, PQR or

RST.

Analog Load Bar

 Unique indication of total load % with respect to the full scale through the 12

LEDs at the right side of the display.

 This is bar graph, where each LED indicates 10% of load.

 To find the total load, count the number of illuminated LEDs, and then

multiply by 10.
