5 Pressure Connection To The Sensors
• For measurements of over pressure (-10.0 mbar ... 350.0 mbar):
Connect plastic tube with internal dia of 4 mm to pressure port "+". Port "-" will not be used!
• For measurements of under pressure (-350.0 mbar ... 0.0 mbar):
Plug the tube to pressure port "-". The measuring range covers then -350.0 to 0.0 mbar.
Note: All values are displayed now as positive values. No minus sign will be shown.
Example: it is possible to measure under pressure down to -350.0 mbar, the display shows then the value
350.0 (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 "+".
higher pressure to port "+".
