Figure 2-30: Medium Size SmartTrac Bar Graph With Display Ranges

Under Tolerance

The Under Tolerance range is labeled “A” in Figure 2-30, and represents the

amount of material between 10% of the target value and the target minus the

negative tolerance value. The bar graph begins to populate the “A” range when

more than 10% of the target has been added. Until the 10% point is reached, no

fill is shown.

Acceptable Tolerance Under Target

Region B in Figure 2-30 represents the zone of acceptable tolerance below the

target value.

On Target

When the measured value exactly equals the target value, an unfilled triangle

indication displays, as shown in Figure 2-30.

Acceptable Tolerance Over Target

Region C in Figure 2-30 represents the zone of acceptable tolerance above the

target value.

Over Tolerance

Region D in Figure 2-30 represents the zone of unacceptable tolerance above the

target value. In Region D, the fill rate reverts to the same rate as used in Region A.

If the measured value is large enough that the number of dot columns required for

display exceeds the number available, the display saturates. Further increases in

the measured value do not affect the graphical display.

Over/Under Mode

The Over/Under SmartTrac visualization may be displayed in medium or large

sizes. If the Target Table’s Tolerance Type is Target Deviation or % of Target, the

target value and the amount of deviation from it are shown, together with a graphic

indicating the direction of deviation (Figure 2-32 and Figure 2-33). If the Target

Table’s Tolerance Type is Weight Value, only the graphic display appears

indicating whether the current value is above, within or below the acceptable range
