Adjustment Procedure
The Adjustment Procedure covers only adjustments. Checks, other than those
that must be made to ensure a step is completed, are in the Performance Check
Procedure. There are actually two Adjustment Procedures, the short–form
version is provided for those familiar with the adjustments, while the longer
(more detailed) procedure is provided for those who need it.Allow 20 minutes of
warm–up time, at normal room temperature (approximately 25
°
C), before
making any adjustments to the instrument.

The Short–Form Adjustment Procedure has the adjustment steps in the same
order as the longer form of the procedure. Adjustment circuit numbers are also
included with the step title. Note also that the Short-Form Procedure can be used
as an index for the long–form.
