Keys
Operation of the Signum 1, Signum 2
or Signum 3 scale involves just a few
keys. These keys have one function 
during measurement and another 
during configuration. Some of the keys
have one function when pressed briefly,
and another activated by pressing 
and holding the key for longer than 
2 seconds. 
If a key is inactive, this is indicated 
as follows when it is pressed:
– The error code “———-” is displayed 
for 2 seconds. The display then returns
to the previous screen content.
You can use Signum 2 or 3 to collect
weight values from two weighing 
platforms, calculate and display weight
values using application programs, 
and assign IDs to the samples weighed.
Configure the display and control 
unit first, using the operating menu 
to prepare the desired application 
program (printer settings, etc.). 
Then you can begin weighing.
