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.
