42 920i Installation Manual
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.Vx and
SC.WLIN#n.Cx commands as required for
additional linearization points.
6. To remove an offset value, clear all weight
from the scale, including hooks or chains used

SC.REZERO#n serial command.
7. Send the KSAVE serial command to save the
calibration changes; send KEXIT to exit setup
mode.
4.4 iRev Calibration
The iRev Calibration Wizard provides step-by-step
scale calibration. With the 920i connected to the PC,
select the Calibration Wizard from the Tools menu on
the
iRev Scales display, then follow the steps listed
below to calibrate the scale. See Section 5.0 on
page 44 for a general overview of the
iRev utility.
1. On the Þrst Calibration Wizard display (see
F i g u r e 4 - 3 ) , s e l e c t w h e t h e r y o u a r e
performing a standard (zero and span)
calibration or a multi-point linear calibration.
Click the
Next button to continue.

2. Next (see Figure 4-4), select the scale you
wish to calibrate.

3. Enter the test weight used to calibrate the
scale (see Figure 4-5). 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.

4. 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 (see Figure 4-6). A message
box appears when the process is complete.
