capacity is selected, place the correct weight on the scale (or set the
calibrator to the correct value). Press and release "ZERO." The scale will
count from "7" to "0." When finished, the scale will display "AVG **."
NOTE: If the scale platform is disturbed during the count down, the
scale will reset the count when the platform becomes stable.
NOTE: If "rg Er" appears on the display, the calibration span is out
of range. Press and release "ZERO" to clear the error and
verify that the correct weight or calibrator setting was used.
Repeat step 4 and 5 if the correct weight was present.
7) After successfully completing the scale calibration, reset the remaining
scale parameters using UNITS or S2 and "ZERO." Be certain to reset
the filter if it was changed during calibration.
8) After the setup and calibration are complete, place the Calibration
switch S1 in the "RUN" mode to resume normal weighing operation.
NOTE: If "Er EP" appears, then the scale calibration was not
successful. Return to step 1 and repeat the calibration.
NOTE: No calibration or setup data is stored until the Calibration
switch S1 is returned to the "RUN" position. If scale power
is removed before returning to the run mode, all calibration
and setup changes will be lost and the previous values will
remain in memory.
Adjustment of span and zero
NOTE: The steps below are intended as a general guideline for
determining the best combination of jumpers in the least
amount of time. This procedure should yield acceptable
results in most instances. This procedure assumes that the
load cell is properly connected.
1) To begin the determination of the span and zero adjustment, remove
jumpers JU7 through JU11. Then connect a load cell simulator (or an
unloaded load cell) to the input (TB1).
2) Apply power and place the scale in the "raw counts" mode of the
calibration menu. Set the calibrator to zero.
3) Adjust R10 from full counterclockwise to full clockwise to determine the
adjustment range. Readjust R10 so that is set to 1/2 of its range.
