Abstract

A method of and apparatus for enabling on-site calibration of an instrument, which measures vibration in a machine to assure that the instrument functions within instrument performance specifications, eliminates the need for shipping the instrument to a remote lab for calibration. In one embodiment a CD containing a database that includes the calibration procedure is provided for use with a laptop computer located on site with the instrument. The laptop is connected to the instrument and the procedure displayed on the laptop is followed to calibrate the instrument. Upon successful completion of the procedure, the laptop is connected to a printer which prints out a certificate of completion of calibration. In an alternative embodiment, the database and procedure are available on a remote computer, which is accessed via an internet connection that is password protected.

Claims

1. A method of enabling on-site calibration of any of a plurality of instruments that measure vibration in a machine to assure that the instrument functions within instrument performance specifications, comprising the steps of

a. providing a calibration device capable of calibrating any of the plurality of said instruments,

b. providing a selected one of said instruments that measures vibration of a machine,

c. providing a database having a calibration procedure for the selected instrument,

d. connecting the calibration device to the selected instrument while the instrument is on-site,

e. connecting the calibration device to the database, and

f. accessing the calibration procedure for the selected instrument in the database to cause the calibration device to calibrate the selected instrument.

2. The method of claim 1, including the steps of

c.1. providing the database on portable storage media, and

c.2. providing an on-site media access device for enabling the calibration device to access the database on the portable storage media.

3. The method of claim 1, including the steps of

c.1. providing the database at an internet-accessible remote site, and

c.2. providing on-site internet access for connection to the database at the internet-accessible remote site.

4. The method of claim 3, including the steps of

c.3. providing password-activated access to the remote site database, and

c.4. providing a password enabling on-site access to the remote database via the internet.

5. The method of claim 1, including the steps of

g. providing on-site means for printing a certificate of calibration, and

h. printing said certificate upon successful calibration of the instrument.

6. The method of claim 1, wherein the database includes calibration procedures for a plurality of different instruments.

7. Apparatus comprising a calibration device capable of calibrating any selected one of a plurality of instruments that measure vibrations in machines to assure that said one instrument functions within instrument performance standards, a database having a calibration procedure for any of the plurality of said instruments, means for connecting the calibration device to a selected one of the instruments while the instrument is on-site, means for connecting the calibration device to the database to access the calibration procedure for the selected instrument in the database to cause the calibration device to calibrate the selected instrument.

8. The apparatus of claim 7, including portable media containing the database, and wherein the means for connecting the calibration device to the instrument includes a portable computer for accessing the portable media on-site.

9. The apparatus of claim 7, including a computer located off-site and containing the database, internet access means for accessing the database via the internet, and password-protection means for limiting access to the database via the internet.

10. The apparatus of claim 9, including password protection means limiting access to the off-site computer database.
