Calling up all data

This function is used to call up the data of all measuring heads, no 
matter in which operating mode they were started. 

To call up the data of individual measuring heads: see section 5.4

Duration of a pass: approx. 3 
seconds for 12 measuring heads 
in a stirring system.

40 cm to 1 m

RUN/ENTER

If the measuring heads do not all respond in the 1st pass of the data query, 
the controller searches for the missing measuring heads in the scanner mode 
for approximately a further 7 seconds. Without having to press another key, 
you can continue the data queries at other locations (e.g. other stirring plat-
forms or other thermal cabinets). 
Approximately 7 seconds after the last call up was performed, the scanner 
mode breaks off automatically and the following display appears:
