Vibration Switch Calibration
The SW6000 has been factory calibrated to standards traceable to the U.S. National Institute
of Standards and Technology (NIST). If the accuracy is in question, the SW6000 output
response can be compared (on an operating machine) with an independent vibration
measurement made in the same axis and at the same location with a calibrated vibration
analyzer. Ensure that the analyzer is configured with the same frequency response as the
SW6000 and with the same unit of measure (i.e. ips pk.). To prevent tampering, there are no
user accessible adjustments available for field recalibrating. If recalibration is required, the
SW6000 should be returned to the factory for recalibration to a traceable standard. In field
installations, the calibration should be verified at least once per year. In test cell applications,
depending upon the severity of handling, correct operation and calibration should be veri

fied each 90-180 days.
