Current Transducer HX 03 .. 50-P/SP2 circuit help

Hi there,

I have been working with Current Transducer HX 03 .. 50-P/SP2 and the rereference circuit I was following is attached. I just replaced the load with a 4 ohm rheostat which has the ability to withstand 1 amp current and I used two DC-DC converters to provide isolated +15V and -15V to the current sensor. (picture attached). Now for 1Amp current I was expecting to see a 0.8V at the DMM that is connected to the pin 4 of my CS. Also I am not seeing any current in the ameter and just finding 4.2mV at the DMM at the CS output.

Please help, I am not very good at circuits and I am using a current sensor for a project purpose for the first time.

Thanks in advance.

Cheers,

Tahsina
