CHAPTER 6: SCALE CALIBRATION
6.1
SCALE CALIBRATION OVERVIEW
The PALLET RUNNER 3000 scale may be calibrated with any precision test weight
between 30 pounds and 3000 pounds. The recommended test weight is 2000 pounds, but
in general the larger the test weight, the more accurate the scale will be.
Before you can calibrate the scale, you must enter the Setup Menu. See Section 5.2.1 for
instructions on how to do this.
6.2
ZERO CALIBRATION (F16)
1. While in the Setup mode, scroll to "
F 16
", then scroll down once using the ZERO/OFF
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/OFF
key again to zero out the displayed value.
3. Press the NET/GROSS 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 indicator calibration.
6.3
SPAN CALIBRATION (F17)
1. While in the Setup mode, scroll to "
F 17
", then scroll down once using the ZERO/OFF
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. Place the test weight on the weighing mechanism.
3. Use the four directional keys (shown in Figure 6-1 below) to adjust the displayed value
to the actual test weight value. Increase the flashing digit by pressing the UNITS key.
Decrease the flashing digit by pressing the ZERO/OFF key. Pressing the ON/PRINT
key or the TARE key will change the position of the flashing digit.
