4.0 Calibration
The Counterpart can be calibrated using the front panel, EDP commands, or Revolution
®
.
Calibration can be performed in two places within the menu: the CALIBR menu shown in Figure 4-1 and the
SCALE submenu shown in Figure 3-6 on Page 22. The CALIBR menu shown in Figure 4-1 is a “quick
access” calibration; for more in-depth scale setup
and calibration, use the menus found under
SETUP
»CONFIG»SCALE (see Figure 3-6 on Page 22).
Calibration consists of the following steps:
• Zero calibration
• Entering the test weight value
• Span calibration
• Optional five-point linearization
• Optional rezero calibration for test weights
u
sing hooks or chains.
The Counterpart requires the WZERO and WSPAN points to be calibrated. The linearity points are
optional, but must NOT duplicate zero or span. During calibration, the TARE(Enter) key acts as a data entry
confirmation key. The soft calibrate key accepts that value.

ing the value, press MENU SETUP to
exit.
4. With WVAL displayed, press TARE(Ente r) or
to display or edit the stored calibration weight
value. Press
TARE(En ter ) to store the WVAL
value and advance to WSPAN.
5. With
WSPAN displayed, press TARE(Enter ) or
to view the A/D count. Place test weights on
the scale equal to WVAL. Press the
