The TympStar must be calibrated when the digital, PC104 or analog board is
repaired, if a transducer is changed or if the probe is repaired
. Probe tone fre-
quency data (Self-Cal data) are stored in the TympStar instrument. All other
data for transducers and pressure are stored in the probe. Normally, circuit
boards or the probe can be replaced with new complements from the factory
without the need for calibration.
GSI recommends quarterly calibration checks for the GSI TympStar along with
annual certification. ASHA requires quarterly electro-acoustic calibration
checks and annual electro-acoustic calibration
. It is good practice to perform
daily biologic checks.
Some aspects of TympStar calibration can be checked singularly without the
need for a complete or routine calibration sequence by simply navigating
through the calibration menus to the desired screen and performing the check.
However, calibration is typically as a complete calibration sequence
or as a routine calibration sequence.
A complete calibration sequence must be performed if the following occurs:
A performance problem is suspected
• A repair has been made to the TympStar involving the digital board,
analog board, PC104 board, probe box or transducers
The complete calibration sequence must include the following:
Loading default data and performing Self-Cal
Contra, Ipsi and probe tone SPL calibrations
• Y (Version 1) or Y/B/G (Version 2) calibration
Pressure system calibration
