Installation Guidelines
Ensure the probe is mounted in a rigid, vibration-free bracket to prevent false readings.
The probe is factory-calibrated for AISI 4140 steel; using different target materials will require recalibration of the scale factor.
For radial vibration applications, the recommended gap setting is 1.27 mm (50 mils), corresponding to approximately -9 Vdc.
ClickLoc connectors should be tightened until they audibly "click" to ensure a secure lock.
Handle with care to avoid damage to the probe tip or cable insulation.
Always power down the monitoring system before connecting or disconnecting transducer components.
