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.

4. Installation
Retention clip for
easy mounting
Panel
Swivel screw
Mounting of BETA 20P/10P is featured with easy “Clip- in” mounting. Push the meter in panel
slot (size 92 x92 mm), it will click fit into panel with the four integral retention clips on two
sides of meter.
If required Additional support is provided with swivel screws (optional) as shown in figure.
As the front of the enclosure conforms to IP50 it is protected from water spray from all
directions, additional protection to the panel may be obtained by the use of an optional
panel gasket. The terminals at the rear of the product should be protected from liquids.
The BETA 20P/10P should be mounted in a reasonably stable ambient temperature and
0
where 0 to 50 C . Vibration should be kept the operating temperature is within the range
to a not be mounted where it will be subjected to minimum and the product should
excessive direct sunlight.

Caution
1. In the interest of safety and functionality this product must be installed by
a qualified engineer, abiding by any local regulations.
2. Voltages dangerous to human life are present at some of the terminal
connections of this unit. Ensure that all supplies are de-energised before
attempting any connection or disconnection.
3. These products do not have internal fuses therefore external fuses must
be used to ensure safety under fault conditions.
4.1 EMC Installation Requirements
This product has been designed to meet the certification of the EU directives when installed
to a good code of practice for EMC in industrial environments, e.g.
1. Screened output and low signal input leads or have provision for fitting RF suppression
components, such as ferrite absorbers, line filters etc., in the event that RF fields
cause problems.
Note: It is good practice to install sensitive electronic instruments that are performing
critical functions, in EMC enclosures that protect against electrical interference which could
cause a disturbance in function.
2. Avoid routing leads alongside cables and products that are, or could be, a source of
interference.
3. To protect the product against permanent damage, surge transients must be limited
to 2kV pk. It is good EMC practice to suppress differential surges to 2kV at the source.
The unit has been designed to automatically recover in the event of a high level of
transients. In extreme circumstances it may be necessary to temporarily disconnect
the auxiliary supply for a period of greater than 5 seconds to restore correct operation.
4. ESD precautions must be taken at all times when handling this product.
