11.Scale grinding
A. First switch on the scale and conduct a calibration.
B. Use weights of 1/3 full load to test the 4 corners and record the shown values.
C. Use a file to grind the “Scale grinding point” corresponding to the lowest display value out of
the four corners.(when grinding for the first time, please test force by means of trial grinding
with small strength so as the avoid damage to L/C), after grinding, press ZERO key to measure
the four corners again.
D. Repeat step B-C until the difference between the four corners and the center is
±1 division, then recalibrate the scale.
E: After grinding the scale, if there are still big differences In the displayed weighing between
the 4 corners and center of the scale, it means malfunction in L/C.
F: Pay attentions to L/C specification when grinding, the smaller Max. Capacity, the weaker
grinding force.
After finished grinding the scale, please install the upper cover, turn the scale upside down,
then tighten 4 fixing screws, and then cover the stainless weighing pan.
12. Switch on the scale, conduct calibration then check weighing functions.
