Rice Lake 820i Programmable Indicator/Controller - Installation Manual - Manual (Page 21)

Configuration 17
The FORMAT configuration of the total scale (see
Figure 3-5 on page 23) should match that of the
source scales. However, the value specified for the
total scale GRADS parameter should be specified as
the sum of the GRADS values for the source scales.
For example: if SCALE 1 is set to GRADS=10000,
SCALE 2 to GRADS=5000, SCALE 3 (the total
scale) should be set to 15000 grads.
The total scale will show an overrange indication if
the maximum ca pacity of any source scale is
exceeded, and show dashes if any source scale reads a
negative value. Source scales will respond to Tare and
Zero operations performed on the total scale.
Total scale function is not supported for
multi-range or multi-interval scales at this
time.
