Totalizing and/or Printing
Before you attempt to do either of these, a few terms and definitions must be
understood. These terms only apply to scales that are cabled together.
Master Scale: If more than one scale is being used, the first scale in line is
referred to as the Master Scale. Normally these scales have continuous output,
If you requested a demand output use the print button on this scale when
printing or totalizing.
Slave Scale: If more than one scale is being used, any scale that is not the
master scale is referred to as a Slave Scale.

scale A scale B scale C scale D Printer
Diagram 2: Example of Master/Slave designations
The master and slave designations are determined by the cable and not the scale itself.
The cable also determines if the scale transmits data on demand (when the print button
is pushed) or continuously. If continuous, the print button doesn't have to be activated
to totalize or print. Please refer to the cabling diagrams
Totalizing
When more than one scale is being used, the last one in line can be used to show the
total weight of all the scales added together. To totalize, turn on the scales in
sequential order starting with the master scale (“scale A") and make sure all of the
slave scales are in the total mode. The indicating bar on the upper left side of the
display is on when in the total mode. This does not mean that the scale is receiving;
only that it is capable of receiving.
If transmitting on demand, press the print button on the master scale and the last
scale in line (slave scale D in the diagram) will show the total weight of all the scales.
Example: Scale A will display the total of A only.
Scale B will display the total of A + B.
Scale C will display the total of A + B + C.
Scale D will display the total of A + B + C + D.
