Calibration
You should periodically calibrate your scale to ensure accuracy. Follow these steps to
calibrate the scale.
Before a two-point calibration (zero and span) you should have on hand at least 10%
of the scale capacity in standard test weights. 100% of capacity is best. You should
have at least 20% of scale capacity if zero-point and two span points are selected to be
calibrated. Again, 100% of capacity is best.
Set the calibration switch to the ON position for calibrating. The switch is located on the
bottom of the scale in a round depression in the base. Push the slide switch, shown in
Figure 4.1, to the position shown for calibration mode.
