For measurements of under pressure
Plug the tube to pressure port "-". The measuring range covers then negative
pressure up to overpressure
Note: All values are displayed now as positive values. No minus sign will be
shown.
Example: it is possible to messure under pressure, the display shows then the
positive value (no minus sign).
For measurements of pressure differences:
Connect both plastic tubes with an internal dia of 4 mm to pressure port "+" and "-";
make sure to apply higher pressure to port "+".
