3.5.3 Disable set-point
The set-point can be permanently turned off by adjusting the potentiometer so that the level is < 1.8 V. This is
achieved by turning the potentiometer fully anticlockwise.
The set-point can also be used to indicate that the gauge is operating correctly by adjusting the potentiometer so
that the level is
10 V, (potentiometer fully clockwise) - in normal operation, the set-point is switched on when the
output of the gauge is below the user adjustable trip level but above 1.8 V.
Note: If the set-point trip level is set to > 9.5 V then the set-point may not switch off when the pressure rises
since the hysteresis point will be > 10.0 V. It would then only switch off when the gauge is disabled.
