Hello all,
For energy calibration in my Energy meter project,
I plan to do this.....
I will have optical fibres connected to the CF output of
i) Standard energy meter ii) energy meter under test.
The two mwters will be connected to the same load.
[ CF output : Calibration frequency, An LED is provided for energy meter
which will blink with a frequency proportional to the Energy]
So i will be getting optical signals.
I have to convert them to pulses.
I have planned to design a micro-controller based design,
which will act as pulse counter. I have a timer which will run for a specified
interval of time. After that time is elapsed,
I will observe the pulses recorded.
Based on m,y observation i will calibrate the offset in MY energ meter.
So, i ...............
Need a circuit which will convert optical signals to pulses.
Please help me out.
Also tell me if there are any products readily available in market.
Thanking you
