The scale would then display the following:
up to 1000 lb by 0.1 lb; up to 453.55 kg by 0.05 kg
1000+ to 2000 lb by 0.2 lb; 453.55+ to 907.1 kg by 0.1 kg
2000+ to 5000 lb by 0.5 lb; 907.1+ to 2267.8 kg by 0.2 kg
5000+ lb by 1.0 lb; 2267.8+ kg by 0.5 kg
To disable the breakpoints the graduation break points should be set to 110% of the
capacity. The scale uses the same graduation from zero to capacity. This turns off the
breakpoint feature.
7. The display shows “AdC AdC AdC AdC.rt rt rt rt”. Press the PRINT/ACCUMULATE button. The display shows the
current setting flashing. This sets the internal A/D conversion time at one of two choices. An
entry of ‘0’ results in the full conversion time for the most stable results. An entry of ‘1’ results
in a reduced conversion time which extends battery life. For the PT300 it is recommended to
leave this set to ‘1’. Note that if this setting is changed, the scale must be recalibrated. Use
the LOCAL/TOTAL button to increment and the ZERO button to decrement the number.
When the desired ADC rate is displayed press the PRINT/ACCUMULATE button.
8. The display shows “AZt
AZt AZt AZt”. Press the PRINT/ACCUMULATE button. The display shows the
current setting. Press the LOCAL/TOTAL or the Zero button to cycle through the auto zero
tracking options. (1 d
1 d 1 d 1 d, 3 d 3 d 3 d 3 d, .5 d 5 d 5 d 5 d. oFF oFF oFF oFF, or 6 d 6 d 6 d 6 d) If the displayed weight is less than the number
of grads shown for a given amount of time, the weight will be zeroed off. When the desired
auto zero tracking setting is displayed press the PRINT/ACCUMULATE button.
9. The display shows “ZEr0
ZEr0 ZEr0 ZEr0.r rr r”. Press the PRINT/ACCUMULATE button. The display shows the
current setting flashing. Use the LOCAL/TOTAL button to increment and the ZERO button to
decrement the number. The zero range is the percentage the zero can move from the original
zero obtained at calibration. The zero button will not work if outside the zero range; and the
display will show “ZEr0
ZEr0 ZEr0 ZEr0.r rr r” with the error icon lit if the zero range is set to 1, 2, or 3. If 4-6 is
selected, the zero button will simply not function when an attempt is made to zero the scale
outside the range. When the number for desired zero range number is displayed press the
PRINT/ACCUMULATE button. (0=off, 1=1%, 2=2%, and 3=5%, 4=1%, 5=2%, 6=5%)
10. The display shows “G G G G rAd rAd rAd rAd”. Press the PRINT/ACCUMULATE button. The display shows the
current setting with the number flashing. Press the LOCAL/TOTAL or the Zero button to cycle
through the graduation options. When the desired graduation setting is displayed press the
PRINT/ACCUMULATE button. (grad options 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, or
100)
Note: The numbering for the “setting the calibration parameters” continues at Span
Calibration.
At this point the display will show “SAvE SAvE SAvE SAvE” for about 1 second and advance to show “CAP CAP CAP CAP”.
