1. General
Successfully completing the Preventive Maintenance Checklist and Calibration Certification
Procedure as outlined will ensure that the instrument is properly maintained and calibrated to
Thermo Scientific specifications.
2. Equipment Required
 Digital Multimeter

 Stopwatch
 Photo Tachometer
 Safety Tester
 Service Manual
 Centrifuge Operating Manual
Note: Check calibration due date on all test equipment before starting certification.
3. Documentation Required
 Preventive Maintenance Procedure and Checklist (Service Manual)
 Calibration Certification Procedure and Form
 Certification Label
 Certificate of calibration for each piece of test equipment used to perform the certification
 Training Certificate

 Complete the Preventive Maintenance Checklist. (calibration data will be filled in after
Certification)
 SPEED
Install a rotor, set the speed control to 3000 rpm (or wanted) and start the centrifuge. When the
speed has stabilized, measure the actual speed with an external tacho(photo tacho on multimeter
where speed = frequencyno conversion). Record measured speed and displayed speed in the speed
section of the certification form. Set the speed control to max. rpm and after stabilization, record
measured speed and displayed speed in the speed section of the certification form. Determine if the
speeds recorded meet the specifications on the form. If the specifications are met, proceed to the
next section. A recalibration of the instrument is not possible.
