CALIBRATION

The pan support on the M500 scale is calibrated prior to packaging and there
should be no difficulty in zero balancing your scale. However, if there is not enough
adjustment in the leveling foot to zero balance your scale, it may be necessary to
re-calibrate the pan support. To accomplish this, remove the pan support top from
the weight holder, using a Phillips screwdriver (Photo 10). The weight holder contains
several non-magnetic weights; if weight needs to be added to pan make sure to
use only non-magnetic material. Magnetic weights might affect the scale's accuracy
(Photo 11). Place all weights and pan support screw into scale pan (Photo 12). Place
pan support back onto weight holder and re-attach pan support to shackle on beam.
Place scale pan containing calibration weights and pan support screw onto pan
support (Photo 13). Adjust leveling foot to its midpoint and add or remove weights
to bring beam into balance (Photo 14). When zero balanced is achieved, as shown
in Photo 8, place all calibration weight material into weight holder and secure pan
support to weight holder (photos 15 and 16). The pan support is now re-calibrated
and ready for use.
