Pressure Measuring Zero, Deaeration of Measuring Hoses
For measuring low differential pressures (under 500 Pa), it is necessary to
reset the pressure measuring of the measuring unit.
The reset function will be activated from the
Sensor zero setting selection
list. You will be led through the reset procedure by gradually emerging
pictures. By rotating the pressure reset knob to the left, the pressure inlets are
hydraulically connected and physically there is zero pressure difference
between them. In the pressure measuring unit, the zero pressure value is set.
Then, turn the reset button to its default position.
The connection of the pressure inlets can also be used to bleed the
connection hoses of the measuring unit. For media temperatures above
50
° C, venting of less than 10 seconds is recommended to avoid
unnecessary heating of the pressure unit measuring circuits.
