If several analyzer boxes are connected with the Control
unit, only the measurement data from one analyzer box can
be displayed at a time, or only one analyzer box can be
activated respectively. This is accomplished by selecting
the analyzer box, see
Measure values of diluted sensors (with enabled
measurement range extension) underlined on the prin
Search for analyzer boxes, page 42.
If several analyzer boxes are connected to a notebook/PC,
the analyzer boxers can be activated and opened parallel
to each other, i.e. to display measuring channels of
different analyzer boxes parallel to one another.
If a notebook/PC or data bus controller (0554 0087) has
several connected and enabled measuring boxes, the
minimum measuring rate changes, depending on the
number of measuring boxes, as follows:
Measuring
boxes
Minimum
measuring rate
1 to 2 1 sec
3 to 4 2 sec
5 to 8 3 sec
9 to 16 5 sec
> Connect the data bus cable to the data bus interfaces.
Please observe the following points when setting up a connection
via data bus cable:
• Use only testo data bus cables
• Do not route data bus cables in the vicinity of electric power
cables.
• Ensure sufficient power supply by supplying each analyzer box
with AC voltage.
• The cables should ideally be plugged in before the system is
switched on. Connecting during operation (hot plugging) is
possible, however, depending on the combination the system
may need to be switched off and on again.
• The connection cannot be separated under load.
• Data bus subscribers: max. 16 analyzer boxes in one data bus
system.
