12.2 Measuring point designation

Each measuring point can be assigned a 10-character alphanumerical desig-
nation denoting as clearly as possible the type of sensor, measuring location,
and / or purpose. This designation is included in all standard measured value
displays. In an output via the interface the measuring point designation ap-
pears in the program header as ´DESIGNATION´ and also in the measured value
list (see Manual 6.6.1).
Input in the Designation function (see 8.5)
Certain control characters at the beginning of the designation have special
functions :
´*J´ This defines a temperature sensor (NTC, PT100) as reference for external
cold junction compensation (see 10.2.6).
´#J´ This means that a cold junction sensor is to be used in the connector for a
thermocouple (e.g. connector ZA9400-FSx with Ntc); see 10.2.6, Manual
6.7.3).
´*T´ This defines a temperature sensor (Ntc, Pt100) as reference for temperature
compensation (see 10.2.4).
´*P´ This defines an atmospheric pressure sensor as reference for atmospheric
pressure compensation (see 10.2.5).
´#N´ This ensures on flow sensors whose measured values (velocity or volume flow)
are acquired with temperature compensation (see 10.2.4) and atmospheric
pressure compensation (see 10.2.5) that these values are converted to stan-
dard conditions (20°C and 1013 mbar); (see Manual 6.7.5).
The remaining 8 characters can be used for the user's own descriptions.
´!´ at the end automatically indicates a specific linearization or multi-point cali-
bration (see 12.11). This cannot be overwritten.

12.3 Averaging mode

For a description of the various averaging modes that can be defined via the
function Averaging mode see Manual, Section 6.7.4.
Function - No averaging :
Averaging start to stop or over individual measuring operations :
Averaging over all scans in a cycle :
Setting the averaging mode, see 8.5:

12.4 Locking the sensor programming

The functional parameters for each measuring point are protected by means of
the locking mode; this can be set to the desired locking level (see Manual
6.3.12). Before programming you must lower the locking mode to an appropri-
ate level. If you see a dot in the display after the locking mode, this means that
this cannot be modified.
