Energy Meter
BCS ( Base Computer Software)
MRI ( Meter Reading Instrument)
It records energy, electrical parameters, tamper and load survey data.
It collects data from the meters using MRI or with modem & telephoneline (RMR).
These data may be used for analysis and monitoring with the help ofSmart 2000 analysis and report tool.
Smart 2000 works on Windows platform. Older version working onDOS was Sems Pack.

Gives logical view of all the meter reading data accordingto various parameters like:
Instantaneous parameter,
Current energy & bill energy data, Time of day energy register data,
MDs,
Abnormal electrical condition data
Perform various other operations called transactions onthe meter like Authenticated MD reset, update Date &Time, Tariff, etc.
Organized storage of meter reading data and consumerdata.
New user(s) with their level of access rights could bedefined and / manage by supervisor based upon their
usage.

Features (Contd)
Exporting the meter data in the industry standard common formats
(like ASCII, CSV) so data can be used by other software for billing orotherwise.
Load survey information is displayed graphically whereby user has anoption to see multiple parameters on the same graph or on a separateview.
All the information displayed on the screen can be printed andpermanent record can be maintained.
Customer can choose what is to be printed. Selection
on category such as Energy, Survey, Transaction, etc
or on subcategory such as Main energy, Bill energy, TOD energy,history of energy registers etc.
