Change of direction (inverse ramp): Release the button.
Press and keep it depressed again within 3 … 5 s (the

briefly).
•
Fine adjustment: Release the button. Briefly press it
again within 0 … 3 s. The zero adjustment value chang-

Switching Functions SP1, SP2, ATM, Status
The gauge provides two adjustable and programmable switching
functions, which are independent of each other. A switching
contact is provided for each switching function:
•
Vacuum pressure set points SP1 & SP2 (default)
•
Atmospheric pressure set point (ATM set point)
•
Gauge status
Switching characteristics and hysteresis of the set
points
•
Low Trip Point (default)
•
High Trip Point
The switching characteristics and the hysteresis of each
set point can only be programmed via the diagnostic
port (
