5.4.2 Testing when the system is operational
A measurement is shown. If despite operational
pressure, no measurement is shown, you can gen-
erate a differential pressure by blocking the differ-
ential pressure lines on one side.
Turn the switch point setting button toward the
measurement until the micro-switch is activated.
