Seeedstudio Electronic Brick Analog Electricity Meter

Hi.
I have bought the electricitymeter for measuring 220V AC Currents. However i cant figure it out. It will deliver an AC output signal? How is it meant to be “Hooked up” with an arduino? I have thrown away the ´jumper and attached a diode on the pins instead, to rectify. And then a small charge condensator mounted on the backside, along with a resistor to hold the voltage steady, but it cant be right. Where do i find examples of hooking it up? and usefull documentation? The .pdf descriptions of the electronic bricks doesnt include this one.
Kind regards
Kumme

what is your Arduino program?
I think that is the reason.

My software is ok. I have several things reading the ad channels. I need information on the hardware.
Kind regs.
