short-duration fault signals
FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01
This function is used for getting rid of unwanted steep-edged faults which
exceed a configurable threshold.
Steep-edged faults ("spikes") are caused by electromagnetic interference
or occasional mechanical jolts. These faults can be suppressed by
inputting a "blanking-out time" of 0...5 s. The time input causes the last
measured value before a spike occurred to be output and the
measurement result is thus no longer affected.
Input can be made in steps of 0.1 s.
If a change in concentration follows immediately upon a fault, this change
may under certain circumstances be displayed after a delay.
When activating this function, the settings for function 50 ("Electrical time
constants") must be taken into account since this function is executed
first.
