Figure 2-12: Summed Scales Over Capacity (left) and Under Range (right)

If one scale included in the Sum Scale is over-capacity and another is under range,

the respective scales will indicate their conditions accordingly, and the Sum Scale

display will show “----------“, indicating an invalid weight value. This condition is

shown in Figure 2-13.

Zero

The Zero function is used to set or reset the initial zero reference point of the

IND780. There are three types of zero setting modes:

• Automatic Zero Maintenance (AZM)

• Power-Up

• Pushbutton

Automatic Zero Maintenance

Automatic Zero Maintenance (AZM) enables the IND780 to compensate for the

buildup of small amounts of weight and track itself back to the center of zero.

Within the AZM operating range (programmable from 0.0 to 9.9 divisions), when

the terminal is in a no motion condition it makes small adjustments to the current

zero reading to drive the weight reading toward the true center-of-zero. When the

weight is outside of the programmed AZM range, this feature is not functional.
