When powered on, a 15-minute inactivity timer will start. If no communication is
detected between the sensor and QuickCollect, DataCollect or ProCollect within 15
minutes, the sensor will automatically power off.
When powered on, a button press of less than 3 seconds will reset the inactivity timer.
When powered on, a press and hold of greater than 3 seconds will power off the sensor.

Vibration and Temperature Measurements
When used directly on a machine, the QuickCollect sensor can collect simultaneous
vibration and temperature measurements. Note that when an external sensor is being
used (external sensor cable connected), a temperature measurement cannot be made.
Vibration
Most machinery problems result in excessive vibration. Mechanical looseness,
imbalance, soft foot (foundation), misalignment, shaft bow, bearing wear, gear defects,
or rotor damage can all be detected using vibration measurements.
When performing measurements, the sensor
s i ratio
output is processed to produce
two very meaningful vibration measurements for each measurement point.
