Reference only. Every digital scale has a different sequence of buttons to calibrate it, and most need a known calibration weight — typically calibrating at both zero (dead load) and span (the known-weight portion). Have a known weight ready before you start. These instructions are provided for reference only and Progressive Scale takes no responsibility for their use. If you need an on-site scale calibration in the CT, NY, or MA area, call 203-792-2854.

Go to R-40 and turn to negative 1/2 the scale capacity (-2500 to -2600lb) then rezero with button re apply calibration weight if incorrect, turn fine span pot 1/4 clockwise for up or 1/4 counter clock wise for down Do not watch the indcator because this will screw you up.
