For an adjustment with filling, simply enter the actual measured value
indicated at the bottom of the display.
The min. adjustment is finished.
For the max. adjustment with density, a filling of the vessel is not
necessary. The numeric examples are stated in chapter Mounting,
Measurement setup, Density and interface of this instructions manual.
Proceed as follows:
1. Edit the % value in the menu item "Max. adjustment" with [OK].
100.00 %
=
0.1000 bar
0.0000 bar
Information:
If the instrument has not yet been adjusted, the displayed pressure for
100 % corresponds to the nominal measuring range of the sensor (in
the above example 100 mbar).
2. Set the requested value with [->] and [OK], for example 0.0 %.
3. Confirm with [OK] and edit the requested mbar value.
4. Set the requested value with [+] and [->], for example 35.3 mbar.
5. Confirm with [OK] and move to the menu overview with [ESC].
For an adjustment with filling, simply enter the actual measured value
indicated at the bottom of the display.
The max. adjustment is finished.
Proceed as follows:
1. Edit the bar value in the menu item "Min. adjustment" with [OK].

2. Set the requested bar value with [+] and [->].
3. Confirm with [+] and move to max. adjustment with [->].
For an adjustment with flow, simply enter the actual measured value
indicated at the bottom of the display.
Information:
The VEGADIF 65 is also suitable for bidirectional flow measurement
(flow in both directions). The selection is carried out in the menu item
"Linearization curve". With the bidirectional flow measurement, the
min. adjustment value must be equal to the negative max. adjustment
value.
Example: Max. adjustment value +100 mbar, as min. adjustment
value, -100 mbar must hence be entered.
The min. adjustment is finished.
