1. Introduction
The 3430 is a panel mounted 96 x 96mm DIN Quadratic Digital metering
system for the measurement important electrical parameters like AC voltage,
AC Current, Frequency, Power, Energy(Active / Reactive / Apparent) .
The instrument integrates accurate measurement technology (All Voltages &
Current measurements are True RMS upto 15th Harmonic) with 3 line 4 digits
Ultra high brightness LED display.
3430 can be configured and programmed
at site for the following :
PT Primary, PT Secondary, CT Primary,
CT Secondary (5A or1A) and 3 phase 3W
or 3 Phase 4W system.

The screen shown on left is of 3 Phase Meter.
The front panel has two push buttons through
which the user may scroll through the
available measurement readings, reset the

3.1. Password Protection
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 four digit number other than
0000, setting a password of 0000 disables the password protection.
3. Programming
The following sections comprise step by step procedures for configuring the
3430 for individual user requirements.
To access the set-up screens press and hold the “
Key simultaneously for 5 seconds. This will take the User into the Password
Protection Entry Stage (Section 3.1).

Potential Transformer primary Digit Edit
Pressing the “ Down” key will scroll the value of
the most significant digit from 0 through to 9 unless
the presently displayed Potential Transformer Primary
Value together with the Current Transformer Primary
Value, previously set, would result in a maximum power
of greater than 666.6 MVA per phase in which 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 significant digit.
The PT Primary value can be set from 100V L-L to 692.8 kV L-L.
Note : the flashing 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 flash.
When the least significant digit has been set pressing the “ Up” key will advance to the
“Potential Transformer Primary Value Confirmation” stage.
