HFA II - i
Calibration and Service Guidelines
NOTES:
1.
Various procedures within the Adjustment/Calibration section make reference to
HFA II - i White Light Verification Data Printouts. How these printouts and
other required service paperwork are utilized on an HFA service call are
described in Section 1. Section 1.3.2 (Three Steps to Completing an HFA II - i
Service Call) and Section 1.3.3 (HFA II - i Field Service Paperwork
Requirements) provide a basic approach to servicing the HFA II - i and the
required paperwork needed to complete the call.
2.
Following any calibration procedure that has calibration values stored on the hard
drive, storage of the new values must be verified by cycling the power off-on before you
perform final system checkout. If values obtained during calibration are not within the
expected range, those values are held only in temporary storage and not written to the
hard drive. When power is turned off, these values are erased and calibration reverts
to its old status.
There are several calibration procedures that require the tool stand to be placed on the
chin rest (see Figure 4-2). Once the tool stand has been installed, ensure that the metal
standoffs touch the forehead rest when performing the indicated calibration.
