6.6 KEY-IN SPAN CALIBRATION VALUE (F20)
Note: This procedure is intended for emergency use only in the case of non-volatile
memory loss. A valid span calibration value, obtained from a successful F17
calibration procedure, must be used.
1. While in the Setup mode, scroll to " F 20 ", then scroll down once using the #2 key. The
display will momentarily show " ET C1 ", followed by value of zero.
2. Use the front panel keys to key-in the actual span calibration value. If you make a
mistake, press the CL key to clear your entry and start over.
3. After setting the exact value, press the NET/GROSS key to save the value.
4. If the entered value is greater than zero, the display will show "
E C 1 " momentarily,
then revert back up to F20. If a value of zero is entered, the indicator will briefly show
" Err 5 ", then revert back to the screen described above in Step # 2.
