Calibration
The indicator is calibrated by following the procedures embedded in P11 (Zero) and P12
(Span) of the Setup Menu. Each procedure enters a value into the indicator's non-volatile
memory:
P11 is the zero value (deadweight)
P12 is the span value (test weight).
The minimum test weight that can be used is 1% of the full-scale capacity. After the two
calibration procedures are executed successfully, a record should be made of both
calibration values in the Calibration Table below using the P 18 View procedure.
NOTE:
This
chapter assumes th
at the indicator is in Setup (“P”) Menu mode.

Serial Number
3.1 Zero Calibration
a. While in the Setup mode, scroll to "P 11", then scroll down once using the
[ZERO]
key to
enter the zero calibration menu. The display will momentarily show "C 0" followed by a value.
This value is the internal A/D count and is useful when trying to troubleshoot setup problems.
b. Ensure there are no test weights on the platform and press the
[ZERO]
key again to zero
out the displayed value.
c. Press the
[NET/GROSS]
key to save the zero point value. The display will show "End C0"
momentarily then revert back to P11. Proceed to the P12 span calibration to complete the
indicator calibration.
3.2 Span Calibration
a. While in the Setup mode, scroll to "P 12", then scroll down once using the
[ZERO]
key to
enter span calibration menu.
b. The display will momentarily show "C 1" for the span calibration, followed by a value
with one flashing digit. This value will be zero with the Decimal Point parameter as selected
in P10. Place the test weight on the weighing mechanism.
c. Use the four direction keys to adjust the displayed value to the actual test weight value.
Increment the flashing digit by pressing the
[UNITS]
key. Decrement the flashing digit by
pressing the
[ZERO]
key. Pressing the
[PRINT]
key or the
[TARE]
key will change the
position of the flashing digit.
d. After setting the exact value, press the
[NET/GROSS]
key to save the value.
