1. INTRODUCTION
The purpose of this manual is to help the user get to know the weight indicator’s various functioning modes, the keys’
functions and the display indications. It is possible that one may incur into the phrase “TECH.MAN.REF.”: this means that
an advanced function is being described (therefore, for the technical personnel) and which is further explained in the
corresponding technical manual.
We advise to carefully follow the instructions for programming the weight indicator; by taking actions not
indicated this manual, one could cause the scale to not work properly.
In addition to having all the characteristics of a high precision scale, the indicator has the unit of measure / pounds
conversion function, the gross weight / net weight conversion, set point on gross weight or net weight, in/out weigh, single-
multiscale repeater, alibi memory, +/- tolerance check, sample weight percentage, freezing the weight on the display, peak
detector, weighs totaliser and piece counter.
The indicator adapts itself to normal weighing applications in either industrial settings, such as during factory production
processes, or that of commerce, such as legal for trade applications, also satisfying the frequently needed ability to transmit
and print the data through its two bidirectional serial ports.
This manual has been made as carefully and exactly as possible; in any case, your suggestions are always
welcome.
