Note: If you do not want to use any channels to define the level values for level monitor-
ing, 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) minimum or
maximum is reached, specify the channel for Hold Channel.
5.
If you want to use the monitoring functions, specify Threshold High and/or Thresh-
old 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 corresponding subsequent stop is mea-
sured as Duration in milliseconds.
The Input is also monitored for exceeding or undershooting the high and low thresh-
olds. If the relevant limit is exceeded or undershot during the runtime, the corresponding
flag is set.
If you specify a channel for Hold Channel, its value when a minimum or maximum of the
channel specified for Input occurs will be retained until the next occurrence of an
extreme value (Captured at Min or Captured at Max).
At stop, all the output values and flags are frozen, which means they remain in their final
status.
If the Input source signal becomes invalid, the peak values and the mean value are cap-
tured and marked as invalid. The Duration output is not influenced by this. The Hold
Channel is not checked for validity.
If the Duration (time between start and stop) is more than 100 s, the mean value is no
longer updated and is marked as invalid.
