Setup & Calibration
The Setup and Calibration utility has several options: Unlock, General, Input calibration, Output
calibration, SPL calibration, and Counter Calibration. Each Audio Integrator is fully tested and
calibrated before it leaves the factory. All calibration constants are stored in non-volatile
memory. Accurate operation depends on this calibration. For this reason, only the General Setup,
Unlock and SPL Calibration menus are covered here. Contact the Sencore Service Department if
you feel your unit needs re-calibration.
Setup – Unlock Firmware
Many of the Audio Integrator functions are part of optional firmware packages. To activate these
additional measurement capabilities, you need to purchase a firmware package from Sencore.
Sencore issues you an unlock code to enter into the SP395. Contact the Sencore sales department
directly to purchase a firmware package. Once a package is unlocked, it will remain available on
that Integrator.
When you receive the unlock code for a firmware purchase, you enter the code into the
instrument using the Utilities function of the Setup & Calibration.
Selecting “Unlock” within the Setup & Calibration submenu is used to enter unlock codes activating test
functions which are part of firmware purchases.
