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:

Training programme

15:30 - 15:40	Introduction and service scope
	Overview of the Celesta system, main service responsibilities and pre-requirements
15:40 - 16:00	Initial checks in Maestro and firmware update
	Device serial number, hardware and firmware versions, enabled licenses and calibration status. Verification of communication between the main unit and the bioamplifier. Use of Firmware Upgrade Manager.
16:00 - 16:10	Connections and replacement of service components
	Safe opening and closing of the instrument. Correct insertion of the bioamplifier mini-HDMI cable and functional verification in Maestro before fastening the screws.
16:10 - 17:00	Transducer calibration
	Difference between first calibration and periodic calibration. Required measurement equipment, couplers and connection setup. Celesta Calibration Tool setup, device information and calibration validity. Step-by-step DD45 calibration: white noise, tone burst, click polarity, chirp and narrow-band chirp. Calibration of both right and left transducers and completion criteria. Specific procedure for IP30 insert earphones. Specific procedure for the B71 bone vibrator, including the artificial mastoid correction factor. Saving the calibration to the device and generating and archiving the calibration report.
17:00 - 17:10	Free-field equalization and checks for HEARLab ACA
	Reference microphone setup and verification. Main principles of free-field equalization and ambient-noise control.
17:10 - 17:30	System performance verification with the loop-back test box
	Correct connection of the loop-back test box and electrode cables. ABR settings required for the verification procedure. Impedance check and verification of stimulus shape, timing and amplitude. Comparison of the two recording channels and verification of all calibrated outputs. Criteria for identifying a possible amplifier or stimulus-generation fault and deciding whether the device must be returned to Inventis.
