4.5 Revolution ® Calibration
To calibrate the indicator using Revolution, the
indicator EDP port must be connected to a PC running
the Revolution configuration utility.
1. Place the indicator in config mode (display
reads SCALE , see Figure 3-6 on page 23) and
remove all weight from the scale platform.
2. From Revolution, select File » New .

The Select Indicator dialog box appears.
3. Select Counterpart and click OK .
4. From the Communications menu, select
Connect .
5. From the left pane, expand the Scale selection
and click the Scale button.
Figure 4-2. Scale Button
6. From the Tools menu, select Calibration Wizard .
7. Click NEXT to begin the Calibration Wizard.
8. Select whether you want to perform a
standard calibration or a standard with
multi-point linearization and click
NEXT .
9. In the text box, enter the test weight value be
used for span calibration.
10. Select the checkbox if you are using chains or
hooks during the calibration, then click NEXT.
11. Remove all weight from the scale and click
Click to Calibrate Zero to begin zero calibration.
If your test weights require hooks or chains,
place them on the scale for zero calibration.
12. When zero calibration is complete, the
Calibration Wizard prompts you to place test
weights on the scale. Place the test weights on
the scale, then click
Click to Calibrate Span .
13. If you chose to perform linear calibration, the
Calibration Wizard now displays prompts
(1–5). Enter the weight value for Linear Point
#1, place test weights on scale and click
GO .
Repeat for additional linearization points,
then click
NEXT .
14. The new and old calibration settings are
displayed. To accept the new values, click
Finish . To exit and restore the old values, click
Cancel .
4.6 More About Calibration
The following topics provide additional information
about compensating for environmental factors
(Section 4.6.1) and diagnostic information for
determining expected zero and span coefficients.
4.6.1 Adjusting Final Calibration
Calibration may be affected by environmental factors
including wind, vibration, and angular loading. For
example, if the scale is calibrated with 1000 lb, a
s t r a i n t e s t m a y d e t e r m i n e t h a t a t 2 0 0 0 l b t h e
calibration is 3 lb high. In this case, final calibration
can be adjusted by tweaking WVAL to 998.5 lb. This
adjustment provides a linear correction of 1.5 lb per
1000 lb.
To adjust the final calibration, return to the WVAL
prompt and press TARE(Enter) to show the test weight
value. Press or to adjust calibration up or down.
Press
Calibrate softkey to save the value, then press to
return to the CALIBR menu.
