Value
SP1-H I The upper switching threshold (Setpoint high)
defines the pressure at which the switching
function is deactivated when the pressure is
rising.
e.g.: SP1-H 1500 I gauge dependent.
If another gauge type is connected, the
VGC50x automatically adjusts the threshold
if required.

The minimum hysteresis between the upper and lower switching
threshold amounts to at least 10% of the lower threshold (logarithmic
gauges) or 1% of the full scale value (linear gauges). This prevents
unstable states.
