Maintenance And Service; Maintenance Schedule - Teledyne T750 User Manual

MAINTENANCE AND SERVICE

Predictive diagnostic functions including failure warnings and alarms built into the
calibrator's firmware allow the user to determine when repairs are necessary without
performing painstaking preventative maintenance procedures.
For the most part, the calibrator is maintenance free; there are, however, a minimal number
of simple procedures that when performed regularly will ensure that the photometer
continues to operate accurately and reliably over its lifetime.
Troubleshooting and service are covered in Section 8 of this manual.
