IND780 User’s Guide

Select Scale

The Select Scale function button is used to switch between scale bases when

multiple platforms are configured for the IND780, including the Sum Scale. It

determines which scale is shown on the display and controlled from the keypad. It

is possible to have multiple scales displayed on the screen simultaneously, in

which case front keypad functions (tare, zero, etc.) affect the selected scale.

Pressing the Select Scale button switches between the scale bases in sequence. To

select a scale directly, entering its number using the numeric keys, then press the

Select Scale button. Figure 2-11 shows a home screen with three scales plus a

Sum Scale, with a highlight indicating that Scale 3 is selected.

Sum Scale

When configured in Setup (at Scale > Sum Scale > Type), the Sum Scale allows

for a logical measurement channel that works from the arithmetic sum of the

weight values from two or more scales. Each scale may have a different capacity

and increment size, but they must all be configured with the same units.

In general, the Sum Scale display behaves like any other independent physical

scale channel. However, any zero command issued to the Sum Scale is redirected

to each of its component scale channels. With regard to the weight display, if one

scale included in the Sum Scale is over-capacity, both its display and the Sum

Scale will show “^ ^ ^ ^ ^“. If a component scale is under range, the display will

also show “v v v v v“. These conditions are shown in the screen images in Figure

2-12. In both cases, the Sum Scale is selected.
