7.3 Setting
Thresholds
for Digital Setpoints
Each setpoint has an upper weight threshold that triggers it. For example, if you set a
threshold of 13kg for setpoint 1, nothing will happen as long as the items on the scale
weigh less than 13kg. As soon as an item is placed on the scale that weighs exactly
13kg, or more, the setpoint will be switched to on (if normally off) or to off (if
normally on).
Setpoints can be activated either by net weight value or by gross weight,
depending on how this was defined in setup.
Setpoints can be either normally open or normally closed, depending on how
this was defined in setup.
To edit weight thresholds for a setpoint:
1.
Press
MENU
and navigate to
WEIGH
>
SETP
.
2. The display shows
SETP1
. Press
ENTER
to select setpoint 1, or press
T
and
ENTER
(the display shows
SETP2
) to select setpoint 2.
3.
The display shows the current threshold for the setpoint you selected.
If you do not want to change this threshold, press
ESC
.
If you do want to change it, proceed to the next step.
4. Enter a new threshold value using the numeric keypad, and press
ENTER
.
