1. INTRODUCTION
The VAF is a panel mounted 96 x 96mm DIN Quadratic Digital Panel Meter for the measurement of
important electrical parameters like AC Voltage, AC Current, RPM, Frequency.
The instrument integrates accurate measurement technology (All Voltages & current measurements
are True RMS upto 15th Harmonic) with 3 line 3 digits Ultra high bright LED display.
VAF can be congured and Programmed On site for the following :
PT Primary, PT Secondary, CT Primary, CT Secondary (5A or 1A)
and System Type 3 phase 3W or 4W or single phase system.
The front panel has two push buttons using which the user can scroll
through different screens and congure the product.

2. MEASUREMENT READING SCREENS
In normal operation, the user is presented with one of the measurement reading screens out of
several screens. These screens may be scrolled through one at a time in incremental order by
pressing the “UP key” and in decremental order by pressing “DOWN key”.

3. Programming
3.1. Password Protection
The following sections comprise step by step procedures for conguring the VAF for individual user
requirements. To access the set-up screens press and hold the “DOWN” and “UP” keys
Simultaneously. This will take the User into the Password Entry screen (Section 3.1).
In Setup mode, if none of the key pressed within 1 min, it will returns operation to the measurement
mode.
Password protection can be enabled to prevent unauthorized access to set-up screens, by default
password protection is not enabled.
Password protection is enabled by selecting a three digit number other than 000,setting a password
of 000 disables the password protection.
Enter Password, prompt for rst digit.
(* Denotes that decimal point will be ashing).
Press the “DOWN” key to scroll the value of the rst digit from 0 through
to 9, the value will wrap from 9 round to 0.
Press the “UP” key to advance to next digit.
In the special case where the Password is “000” pressing the “UP” key
when prompted for the rst digit will advance to the “Password
Conrmed” screen.

Note : The ashing decimal point indicates the cursor position, a steady decimal point will be present
to identify the scaling of the number until the cursor position coincides with the steady decimal point
position. At this stage the decimal point will ash.
When the least signicant digit has been set, pressing the “UP” key will advance to the “Potential
transformer Primary Value Conrmation” stage.
Potential Transformer Primary Digit Edit
Pressing the “DOWN” key will scroll the value of the most signicant digit
from 0 to 9 unless the presently displayed Potential Transformer Primary
value is less than 799 kilovolts in that case the digit range will be
restricted.
Pressing the “UP” key accepts the present value at the cursor position
and advances the cursor to the next Less signicant digit.
Initially the PT value must be selected pressing the “DOWN” key will move the decimal point position
to the right side until it reaches # # #. after which it will return to #. # # with x1000 annunciation.
Pressing the “UP” key accepts the present multiplier (Decimal Point position ) with x1000 annunciation
and advances to the “Potential Transformer Primary Digit Edit” Screen.
Note : PT Values must be set as Line to Line Voltage for Primary as well as Secondary for all
system types (3P3W/3P4W/1P2W).
