Hi

I want to calibrate a scale with four loadcells. every two loadcells have been connected to a loadcell junction box and output signal is connected to Siwarex WP321. In fact, I have four loadcells, two junction boxes, and two Siwarex WP321 modules for the scale. I have tried to calibrate the scale in several ways (automatic and manual, add measured values, calculate average value).  But, I don't know what way is the best. How can I calibrate this scale with minimum error?

Dear Siwarexi,

Thank you for recommendation. The scale are suggested and constructed by vendor due to importance of uniformity. I recommend them to connect all four load cells in parallel to one WP321 module to but they don't accept this way due to technical problem.

I will use your steps to calibrate the scale tomorrow and announce the results.

Dear Siwarexi,

Your way worked. Thank you for your help.
