4.2.3 Full Scale Adjustment
The full scale adjustment is a span-correction of the measure-
ment signal. Real pressure and pressure reading of the trans-
ducer must be above 800 mbar.
If applicable a zero adjustment should be carried out before
any full scale adjustment!
For full scale adjustment a calibrated pressure gauge is needed as standard.
According to the formula in chapter 4.1 the output signal of your DI2000 or
DU2000 should equal the pressure reading p(mbar) of the standard gauge.
For adjustment first remove the rubber caps from both buttons, then adjust the
signal output by means of the "up" and "down" buttons. If a button is permanently
pressed the signal will change continuously in the respective direction.
If no further button is pressed for an interval of 5s, the adjusted value is set.
Now insert the rubber cap again.
