Load cell problem

i am using four 50 kg resistance strain load cell,Load combinator, HX711 amplifier and arduino uno to get the weight.

In my load cell resistance between blue wire and black was 2k and that between blue & red and red & black was 1k. So i connected blue wire to '+' , black wire to '-', and red to 'C'.

E+,E-,A+,A- of the load combinator was conneceted to the corresponding pins in HX711.HX711 was then connected to the arduino

I am using the following library and the example code available here GitHub - bogde/HX711: An Arduino library to interface the Avia Semiconductor HX711 24-Bit Analog-to-Digital Converter (ADC) for Weight Scales.
When i read the output from the load cells i am getting a lot of random values even when no weight is placed on them.The output that i am getting even with a known weight was also wrong.

Can anyone help me to troubleshoot the problem?

A schematic of your setup would be easier to understand than a description. Data sheets for the load cell and "load combiner" would help, also.

Thanks for your quick reply

I am attaching the load combinator schematic.It helps us to arrange load sensor in the wheatstone bridge formation.
I have connected the wires from the load sensor to the JP1,JP2,JP3,JP4 in the load combinator

Also, might be (past) time to show your code, some photographs of your setup, and example output for no load and known load.
