Using your VibraCheck Limited and VibraCheck II:
Sensor Mounting
: Each VibraCheck Limited and VibraCheck II is equipped with
an accelerometer with a high-strength magnetic base and touch spike for sensor
mounting. The accelerometer magnetic mount is capable of a wider frequency
measurement than the spike. The spike is designed for measurement of vibration
signals that range below 1 khz. It is always recommended to use the magnetic
base where applicable. The touch spike is ideal for non-ferrous surfaces or limited
areas.
G-Probe
: Changing between the spike and magnetic base is easy during in-fi eld
measurement.
Step 1: Attach the G-Probe as shown to fi t the magnetic base.
Step 2: Turn the G-Probe to the correct position.
Headphones:
When collecting data with the VibraCheck II, you may use the
optional headphone to listen to the mechanical noise sensed by the accelerometer.
For an experienced operator, this is a good way to fi nd out the problems of a
machine. For example, when a rolling bearing is damaged, it will generate
certain pattern of noise that can be heard clearly with the headphones. Simply
attach the headphone cable to the 6-pin connector on the VibraCheck II as
illustrated.
