help !!

hi... i want want to build a device which will find the error in a energymeter (i.e meter is fast or slow) and display the percentage error by comparing the impulse of the energymeter with a standard reference

the standard reference here is a 0.1 Class meter.

the impulse of the energy meter is to be detected through a LED connected to it

can any one tell me how i should go about building this thing
