8)
Apply a calibrated load to the center of each weigh pad. This may
be accomplished by loading the weigh pad with a truck wheel
previously weighed at a certified scale. Best results will be
obtained by loading the pad as near to the rated pad capacity as
possible.
Note: An unconnected weigh pad should be placed under the opposite
wheel on the axle for the most accurate results.
9)
Remove the cap screw located on one side of the weigh pad under
the handle (see Figure 1).
10) Turn the adjustment screw until the meter displays the correct
weight.
11) Remove weight from the pad and check for return to 0, Repeat
steps 2 through 10 if the meter does not return to 0.
12) Replace the cap screw.
13) Repeat steps 2 through 12 for each pad.
Note: Measurement Systems International, Inc., will calibrate, for a
fixed charge, systems that are returned to the factory. Systems must be
returned freight prepaid.
INTERNAL ZERO ADJUSTMENT
If the display reading is greater than a few percent of the system weight
capacity when the meter is first turned on (with no weight on the pads),
you may want to internally re-zero the meter as part of the system
calibration procedure since the overrange capacity of the meter may be
affected. To acconplish this do the following:
1)
With all weigh pads connected and unloaded, remove the four
front panel screws. Lift the front panel out away from the meter
case to expose the circuit boards on the rear side of the panel.
Find the zero adjust control screw near the bottom of the com-
puter board (rear board) slightly left of the center.
2)
Turn the ON/OFF switch off, then on again and wait a minute for
the display to stabilize. Then adjust the zero control screw until
zero is displayed.
3)
Turn the meter off and replace the front panel, the meter is left on
when actual weighing is not taking place.
