The Revolution III Calibration Wizard provides
step-by-step scale calibration. With the 720i connected
to the PC, select the scale and click on the scale icon in
the Calibration Wizard from the Tools menu on the
Revolution III Scales display, then follow the steps
listed below to calibrate the scale. See Section 5.0 on
page 50 for a general overview of the

2. Enter the test weight used to calibrate the scale.
If chains or hooks are used to hold the weights,
check the box below the test weight value
entry. This adds a rezero step to the calibration
sequence.
3. Remove all weights from the scale. If chains or
hooks are used, place them on the scale. Press
the
Calibrate Zero button to perform the zero
calibration. A message box appears when the
process is complete.
4. Apply the test weights to the scale. Press the
Calibrate Span button to perform the span
calibration. A message box appears when the
process is complete.
5. If the option for chains or hooks was selected
in step 2, the Rezero display is shown. Remove
all weights from the scale, including chains or
hooks. Press the
Re-Zero button to calibrate the
zero offset.
6. If performing a multi-point linear calibration,
up to five other calibration weight values can
be entered on the display. The weights must be
in ascending order and must not include zero
or the span weight. Enter the weight values and
click the
Go button to calibrate each point.
7. Review the new calibration values then click
Finish to close the Calibration Wizard. To
