28 Installing the Enwatch
Saving the machine speed with a spectrum
In the Hardware Setup program, when adding or editing an Enwatch unit,
click the Trigger Channel tab.
The Timeout is defined in seconds (the default is 5 seconds). The Number of
pulse per rev default is 1 pulse per revolution. Click the Channel tab and
assign the correct Trigger channel to the vibration channel. This example
uses trigger channel 1 for the measurement on input channel 1.
When the Enwatch unit collects data for channel 1, the unit checks trigger
channel 1 to get the machine speed reading. The speed reading comes back
with time waveform data and gets stored into the database with the vibration
data.
