Calibration 55
4.0 Calibration
The Counterpart can be calibrated using the front panel, EDP commands, or Revolution ® .
Note
Calibration can be performed in two places within the menu: the CALIBR menu shown in Figure 4-1 and the
SCALE sub-menu shown in Figure 3-8 on page 28. 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 3-8 on page 28).
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 using hooks or chains.
Note
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.

1. Press the MENU SETUP button, and then press until the display reads CALIBR .
2. Press TARE (Enter) or to go to the scale to be calibrated. Press TARE (Enter) or to go to WZERO . Press
TARE (Enter) again to display a value and press the Calibrate softkey to Calibrate WZERO.
Note
If you do not want to calibrate zero, press Menu to exit.
3. The indicator displays CALIBRATING while calibration is in progress. When complete, press TARE (Enter) or
to advanced to the next prompt ( WVAL ).
Note
To view the new AD count, repeat Step 3, but instead of pressing TARE (Enter) while viewing the value, press
MENU SETUP to exit.
4. With WVAL displayed, press TARE (Enter) or to display or edit the stored calibration weight value. Press
TARE (Enter) 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 Calibrate softkey to calibrate WSPAN.
