If the <ZERO> button is released for more than 5 s, the
gauge returns the measurement mode.
The factory setting of the reset value is 1% F.S. above
the Low Trip Point and 1% F.S. below the High Trip
Point (hysteresis).
If after programming of the hysteresis the button <SP> is
pushed, the factory setting of the hysteresis (1%) is
reactivated.

Adjusting setpoint SP2
The adjustment procedure is the same as for setpoint SP1.
4.3.2 Programming the ATM Setpoint
The vacuum pressure setpoints SP1 & SP2 can be programmed
to atmospheric pressure setpoint (ATM setpoint) via the diag-
nostic port (

The threshold value of the ATM setpoint is defined as a factor of
the current atmospheric pressure. The switching contact switch-
es when the pressure in the vacuum system has reached the
defined threshold value.
