4.3.3.2. n-point adjustment
With an n-point adjustment, the parameters at the 3-6
measurement points are adjusted to the reference value. The
reference conditions are obtained by using a precise pressure
sensor that should be 5-times more accurate than the transmitter.
1 Positive pressure connection
2. Negative pressure connection
3. Pressure sensor
The number of measuring points is set to 3 by the factory
and can only be changed using the P2A software (see
n-
point adjustment , page 63).
The n-point adjustment must always be carried out to its full
extent and in good time at all selected measurement points.

A precise pressure sensor (5-times more accurate than the
transmitter, e.g. DPC precision pressure sensor from testo
industrial services) is available.
1. Connect the positive output of the pressure sensor ( 3 ) to the
positive pressure connection of the transmitter ( 1 ) and the
negative output of the pressure sensor ( 3 ) to the negative
pressure connection of the transmitter ( 2 ).
2. Transfer the reference pressure value created with the pressure
sensor into the P2A software (see n-point adjustment, page 63)
or enter it via the user menu (see Performing analog
adjustment, page 37).
3. Repeat step 2 for all of the measuring points.
4. Disconnect connections between the pressure sensor and the
pressure connections of the testo 6383.
