Using the breakpoint settings from the previous example, the scale would display the
following information:
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 point settings should be set to 110%
of the capacity. The scale uses the same graduation from zero to capacity. Setting the
breakpoint to 110% of capacity effectively disables the breakpoint feature.
6. The display shows ".". Press the PRINT/ACCUMULATE button. The display
shows the current ADC Rate setting in flashing mode. There are two ADC rate
settings available for selection. To achieve a full conversion time and the most
stable results, select the "0" setting. A setting of "1" will result in a reduced
conversion time, but will extend battery life. It is recommended the ADC Rate be set
to "1". NOTE: When the 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 has been selected, press the
PRINT/ACCUMULATE button to save the entry.
7. The display shows "". Press the PRINT/ACCUMULATE button. The display will
show the current AZT setting. Press the LOCAL/TOTAL or the ZERO button to cycle
through the available auto zero tracking options (, , ..  or ). 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 to save the entry.
8. The display will show ".". Press the PRINT/ACCUMULATE button. The display
shows the current ZERO Range setting in flashing mode. Use the LOCAL/TOTAL
button to increment and the ZERO button to decrement the number. The ZERO
Range setting 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. The display
will show the message "." with an error icon lit up if the ZERO Range is set to
1, 2 or 3. If a setting between 4 and 6 is selected, the ZERO button will not function
when an attempt is made to zero the scale outside the range. When the setting for
desired ZERO Range number is displayed (0=off, 1=1%, 2=2%, and 3=5%, 4=1%,
5=2%, 6=5%), press the PRINT/ACCUMULATE button to save the entry.
9. The display shows "g". Press the PRINT/ACCUMULATE button. The display
shows the current Graduation Size setting in flashing mode. Press the
LOCAL/TOTAL or the ZERO button to cycle through the graduation options (0.02,
0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50 or 100). When the desired graduation setting
is displayed press the PRINT/ACCUMULATE button.
The display will show "" for approximately 1 second and then advance to show the
message "". The scale is now ready to proceed to weight calibration.
