CHAPTER 6: CALIBRATION
6.1 CALIBRATION
OVERVIEW
The scale is calibrated by following the procedures embedded in F16 (Zero) and F17 (Span) of the
Setup Menu. Each procedure enters a value into the scale's non-volatile memory - F16 the zero
value (deadweight) and F17 the span value (test weight). The minimum test weight that can be
used is 1% of full-scale capacity.
NOTE:
This chapter assumes that the scale is in Setup (“F”) Menu mode. If the scale is not in
Setup Menu mode, refer to Chapter 3 for instructions.
6.2
ZERO CALIBRATION (F16)
1. While in the Setup mode, scroll to "
F 16
", then scroll down once using the 6 key to enter zero
calibration menu. The display will momentarily show "
C 0
" followed by a value. This value is the
internal A/D count and can prove useful when trying to troubleshoot setup problems.
2. After making sure that there are no test weights on the platform, press the ZERO key to zero
out the displayed value.
3. Press the SAMPLE/SAVE key to save the zero point value. The display will show "
EndC0
"
momentarily, then revert back up to F16. At this time, proceed to the F17 span calibration to
complete scale calibration.
6.3
SPAN CALIBRATION (F17)
1. While in the Setup mode, scroll to "
F 17
", then scroll down once using the 6 key to enter span
calibration menu.
2. 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 selected in F10. Place the
test weight on the platter.
3. Use the numeric keys to enter the test weight value. Please note that the decimal point is fixed so
that if you are entering, for example, 2 lb, you need to type “2” followed by zeroes until the “2” is
to the left of the decimal point.
4. After setting the exact value, press the SAMPLE/SAVE key to save the value.
5. If the calibration was successful, the display will show "
EndC1
" momentarily, then revert back up
to F17.
6. If the calibration was
not
successful, one of the error messages below will appear. Take the
indicated action to correct the problem, then perform a new calibration.
"
Err0
" - The calibration test weight or the adjusted keyed-in weight is larger than the full
capacity of the scale. Change the calibration test weight or check the input data.
"
Err1
" - The calibration test weight or the adjusted keyed-in weight is smaller than 1% of the full
capacity of the scale. Change the calibration test weight or check the input data.
"
Err2
" - The internal resolution of the scale is not high enough to accept the calibration value.
