Rice Lake 120 Plus Digital Weight Indicator - Manual (Page 23)

Configuration 19
is in progress. When complete, REZERO is displayed.
6. Optional: The rezero function is used to remove a calibration offset when hooks or chains are used to hang
the test weights.
• If hooks or chains were used during calibration, remove these and all test weights from the scale. Press
the enter key to rezero the scale. This function adjusts the zero and span calibration values. When
complete, CAL is displayed.
7. Press the 2 key until the display reads EXIT Y , then press enter key to exit configuration mode.
When editing numeric values, press the enter key to allow the numeric entry, and then press the clear key to
clear the values. Press numeric keys (0~9) to enter the value. Press the enter key to save the value entered and
return to the level above.
The calibration process is depicted in the following figure:
Figure 3-6. Calibration Process
NOTE 1: Place test weights.
NOTE 2: Use arrow keys, see Figure 3-2 on page 13 to set the maximum weight value.
NOTE 3: Optional - use only when hooks or chains were used during calibration. To recalibrate zero, remove these
and the test weights from the scale.
3.3.3 EDP Command Calibration
To calibrate the indicator using EDP commands, the indicator EDP port must be connected to a terminal or
personal computer. See Section 2.2 on page 7 for EDP port pin assignments; see “Appendix A Electronic Data
Processing Commands EDP” for more information about using EDP commands. Once the indicator is connected to
the sending device, do the following:
1. Place the indicator in configuration mode (the 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 WZERO command to calibrate zero. The indicator displays *CAL* while calibration is in progress.
NOTE: During EDP command calibration, the *CAL* message remains on the display. Once the calibration
is complete, the OK message appears on the display.
3. Place test weights on the scale and use the WVAL command to enter the test weight value in the following
format: WVAL=nnnnnn<CR>.
4. Send the WSPAN command to calibrate span. The indicator displays *CAL* while calibration is in progress.
5. To remove an offset value, clear all weight from the scale, including hooks or chains used to hang test
weights, and then send the REZERO command. The indicator displays *CAL* while the zero and span
calibrations are adjusted.
