1. Introduction
The Series is a panel mounted 96 x 96mm and 48X96mm Digital Panel BETA 20P / 10P
Meters for the measurement of AC Voltage and current in single phase systems.
The instrument integrates accurate measurement technology. The measurements are
True RMS upto 15th Harmonic. The parameters are displayed with Ultra high brightness
LED display with 20mm and 14mm Digit height options.
CT Primary, CT secondary.
The front panel has two push buttons for user interface to
scroll through the available parameters the two keys has
function as follow :
2. : Scrolls the parameters in Reverse of above sequence.

Programmable DPM can be configured and Programmed
at site for the following : PT Primary, PT Secondary,
1. : Scrolls through parameter in upward sequence.
Display sequence BETA 20P : System voltage, max.
Value, min value and then back to system Voltage.
Display sequence BETA 10P : system Current, max value min value and back to system current.
These DPMs come with 14mm and 20mm Display options, which enables to take readings
from long distance. The unit of display is illuminated form back side with bright LEDs,
which overcomes the problem with conventional LED annunciators that could not be
clearly understood the parameter being displayed from a distance.
