Celesta Service Training

Duration: 2 hours
Trainer: Andrea Stoppato – Inventis Service Team

Training purpose

The purpose of this training is to provide distributor service technicians with the practical knowledge required to perform the authorized service, calibration and verification procedures for Celesta.
Particular attention will be given to transducer calibration and system performance verification, as these are the most critical activities for ensuring reliable operation in the field.
At the end of the session, participants should be able to carry out the documented procedures consistently and identify when an issue can be managed locally or must be escalated to Inventis.

Pre training preparation

The following documents are provided and should be reviewed before the training session:
