Question { 18613 }

Is there any interfacing sofware to build communication
between a PC and ER300P model L&T make trivector meter via
RS485 port which is available in the meter and is there any
data acquisition card available to store the acquired data
from the meter into the system

Answer

I'm using this meter to study the power utilization for
several load settings in a complex theromchemical
plant.....At the begning of every measurment I want to
round off the start point of the power consumption reading
to 4 digits (ex:xxxx0000)....so that I can apply my algo on
the readings which I get at the end of my measurement.

Does any one of you know how to do it?

Answer

Thank you very much George.
As I know from ER300P manual....we have a programing
password with which I can change some settings of the meter
like CT\PT ratio and RTC etc...So can I use the same
programing password to write to the location of current
power consumption?

Thank you again.

With best regards,
Anis
