1. Place the indicator in setup mode (display reads
CONFIG
) and remove all weight from the scale platform. If your test
weights require hooks or chains, place the hooks or chains on the scale for zero calibration.
2. Send the SC.WZERO#
n
serial command (where
n
is the number of the scale) to calibrate zero.
3. Place test weights on the scale and use the SC.WVAL command to enter the test weight value in the following format:
SC.WVAL#
n
=
vvvvv
<CR>
4. Send the SC.WSPAN#
n
serial command to calibrate span.
5. Up to five linearization points can be calibrated between the zero and span calibration values. Use the following
commands to set and calibrate a single linearization point:
SC.WLIN#
n
.V1=
vvvvv
<CR>
SC.WLIN#
n
.C1<CR>
The SC.WLIN#
n
.V1 command sets the test weight value (
vvvvv
) for linearization point 1. The SC.WLIN#
n
.C1
command calibrates the point. Repeat using the SC.WLIN#
n
.V
x
and SC.WLIN#
n
.C
x
commands as required for
additional linearization points.
6. To remove an offset value, clear all weight from the scale, including hooks or chains used to hang test weights, then
send the SC.REZERO#
n
serial command.
7. Send the KSAVE serial command to save the calibration changes; send KEXIT to exit setup mode.
4.4 Revolution Calibration
The
Revolution
Calibration Wizard provides step-by-step scale calibration. With the
820i
connected to the PC, select the
Calibration Wizard from the Tools menu on the
Revolution
Scales display, then follow the steps listed below to calibrate the
scale. See
Revolution
utility.
1. On the first Calibration Wizard display (see
), select whether you are performing a standard (zero and span)
calibration or a multi-point linear calibration. Click the
Next
button to continue.

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 restore the current calibration
values, click
Cancel
