Interval duration
The interval duration is acquired with the acquisition described above. The counter value between two
thresholds on is detected, scaled, and sent correspondingly to the measuring range setting.
Pulse duration
The pulse duration is acquired with the acquisition described above. The counter value between the
threshold on and the threshold off is detected, scaled, and sent correspondingly to the measuring range
setting.
The thresholds on and off do usually differ and cause different results of the pulse duration if the signal
edges are low, depending on the defined thresholds.
Pause duration
The pause duration acquisition corresponds to the pulse duration acquisition with inverted input signal.
Mode – Ignore Frequency Drop
The module supports in the mode tab sheet a function called: “Ignore frequency drop”. With this function it is
possible to measure RPM when several teeth on the reflector or missing.
The drop voltage can be configured in the PlugIn options:
