Configuration at the analyzer
Open the path:
1. E
XTRAS
2. Switch the menu-point "External control" from "OFF" to
the connected signal input.). When the external control is activated an arrow symbol will appear at the
title line.
3. If a valid input state (>0) is present, an arrow in the title line will appear. The analyzer is now slave and
will perform the measurement until it gets another command from the master unit. Some external control
settings can be configured. This can be found at the path:
The user has the opportunity to set the zeroing time, suction/response time and stand-by purge time.
Case 1: Stand-by
The Stand-by modus will be activated if the input state is higher than the number of sample points (example: 4
sample points and input state 5...15). The Stand-by modus has the following pass:
- Purging with zero gas (for the configured duration)
- Standby until the input state is below or equal the number of sample points (e.g. 4 sample points and input state
1.4)
Case 2: External control of a sample point
-Zeroing: First the zeroing will be done. The duration of the zeropoint can be set at the menu ext. crtl. (see point
"configurated at the analyzer" in the same chapter).
-Gas sampling: The gas sampling is for purging the entire system and give the analyzer enough time for
response. (Response time). To set the suction/ response time, see point "configurated at the analyzer" in the
same chapter.
-Measurement: The measurement will be started after the response/ suction time is finished. It will be only abort,
if the user changes the status of the external signal sources. The chart below shows the possible statues, which
can be set at the analyzer:
