The Instrument is a panel mounted 96x 96mm DIN Quadratic Digital
metering system for the measurement& display of basic electrical parameters like
AC Voltage, AC Current, Frequency, kVA, Ampere Demand and kVA Demand.
The instrument integrates accurate measurement technology (All
Voltage& Current measurements are True RMS upto 15th Harmonic) with3 line4
The instrument can be configured and
programmed at site for the following: PT
Primary, CT Primary, CT Secondary (5A or 1A)
The front panel has two push buttons through
may scroll through the
available measurement readings, reset the
demand readings and configure the product.

Password protection is enabled by selectinga four digit number other than 0000,
setting a password of 0000 disables the password protection.
In normal operation the user is presented with one of the measurement reading
screens out of available screens. These screens may be scrolled through one ata
time in incremental order by pressing the “
Up key” and in decremental order
by pressing “
Down key”.
Enter Password, prompt for first digit.
(* Denotes that decimal point will be flashing).
Press the “
Down” key to scroll the value of the first digit
from0 through to 9, the value will wrap from 9 round to 0.
Press the “
Up” key to advance to Up digit.
In the special case where the Password is “0000” pressing
the “
Up” key when prompted for the first digit will
advance to the “Password Confirmed” screen.
Enter Password, first digit entered, prompt for second digit.
(* Denotes that decimal point will be flashing).
Press the “
Down” key to scroll the value of the second
digit from 0 through to 9, the value will wrap from9 round
