´#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); s. 11.2.6, Manual 6.7.3).
´*T´ This defines a temperature sensor (Ntc, Pt100) as reference for temperature
compensation (see 11.2.4).
´*P´ This defines an atmospheric pressure sensor as reference for atmospheric pres-
sure compensation (see 11.2.5).
´#N´ This ensures on flow sensors whose measured values (velocity or volume flow)
are acquired with temperature compensation (see 11.2.4) and atmospheric pres-
sure compensation (see 11.2.5) that these values are converted to standard con-
ditions (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 13.11). This cannot be overwritten.
13.3 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 mode : -----
Averaging start to stop or over individual measuring operations :
CONT
Averaging over all scans in a cycle :
CYCL
Setting the averaging mode, see 9.5:
Averaging mode: CONT
13.4 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 appropriate
level. If you see a dot in the display after the locking mode, this means that this
cannot be modified.
Locking level Locked functions
0 None
1 Measuring range + element flags + output mode
3 + units
4 + zero-point correction + gain correction
5 + base value + factor + exponent

In the

menu the functions are listed from top to bottom
in such a way that the locked functions cannot be selected.
13.5 Limit values
Two limit values (MAXIMUM and MINIMUM) can be programmed per measuring
channel. Exceeding one of these limit values is treated as a fault (in the same
