Process pressure measurement
Set up VEGABAR 67 in the following sequence:
1. Select application "Process pressure measurement"
2. Select the unit of measurement
3. Carry out a position correction
4. Carrying out zero adjustment
5. Carry out span adjustment
In the menu item "Adjustment unit" you select the physical unit in
which the adjustment should be carried out, e.g. mbar, bar, psi…
The position correction compensates the influence of the mounting
position or static pressure on the measurement. It does not influence
the adjustment values.
In the menu items "zero" and "span" you determine the span of the
sensor, the span corresponds to the end value.
Information:
The steps 1, 3 and 4 are not necessary for instruments which are
already preset according to customer specifications!
You can find the data on the type label on the instrument or in the
menu items of the zero/span adjustment.
