Why does my HI 1746WS read 50 lbs after doing a C2® calibration?

The C2® calibration on my HI 1746WS yields a weight of 50 lbs when I push the "Button". The scale is empty, so it should read 0 lbs. What should I change on my HI 1746WS to get an accurate calibration?

The reference point the HI 1746WS module uses for the "Button" calibration is the CalLo Weight. You should verify this is set to the amount of weight on the scale (zero if empty scale) at the time of the "Button" calibration.
