Starting up the ClipX
If one of the source signals is invalid, all the output signals will become invalid
as well. The calculation will nevertheless be performed and the result exported.
7.4.2.2 Tolerance window
The tolerance window combines several functions: Acquisition of minimum,
maximum, peak-to-peak and arithmetic mean and monitoring of exceed-
ing/undershooting a limit for a definable period of time. You can also determine
the value of another channel when an extreme value is reached.
Note: If you do not want to use any channels to define the level values for level
monitoring, first define the levels with User-defined Constants (Calculated
Channels menu at bottom).
Procedure
1. For Input, enter the channel to be monitored.
2. For Start with define a digital signal that starts the functions on a rising
edge. All output signals (min, max, etc.) and the flags for level monitoring
are reset at the start.
3. For Stop with define a digital signal that stops the functions on a rising
edge. All output values (min, max, etc.) and the flags for level monitoring are
frozen at the stop.
4. If you want to determine the value of another channel when a (new) mini-
mum or maximum is reached, specify the channel for Hold Channel.
5. If you want to use the monitoring functions, specify the Threshold High
and/or the Threshold Low.
6. Finally, specify the outputs and flags for the desired results.
Function
After the start, all values and the flags are first reset. Then the signal at the
Input is checked for minimum and maximum and the oscillation bandwidth and
mean value are calculated. The mean value is calculated across a maximum of
100,000 values (100 s). The amount of time between a start and the corre-
sponding subsequent stop is measured as Duration in milliseconds.
The Input is also monitored for exceeding or undershooting the high and low
