When enabled, the deglitch filter works by monitoring the data line for changes in state. If a change is detected a timer will
start, if no further changes of state are detected by the time the timer has reached the deglitch time, the digital input line will
change state.
If a change in state is detected before the timer has reached the deglitch time, no changes will be made to the digital input
line.
Note: If the digital input is continually changing state at a frequency faster then the set deglitch time, then no changes in
state will be reported.
Please read the relevant section of the control unit manual to find out how to wire external hardware to the control unit.
3.4.7 Delays
This tab is an advanced feature. The control unit has a table of software delays that control the length of transition states –
for example how long to wait when switching between a Faraday and multiplier detector.
You should never normally need to change the delays from the standard factory defaults. However, in exceptional
circumstances an MKS support engineer may recommend changes to one or more of these standard settings.
This topic is not covered any further in this manual.
