6-136. SC300 Hardware Adjustments

Before beginning SC300 hardware adjustments, it must determined which
revision of the option is installed in the instrument. To do this, remove the
top cover of the calibrator and look at the circuit board tab protruding
through the guard cover that is closest to the right front corner of the
calibrator. If this tab is marked A4, proceed to the"SC300 Hardware
Adjustments for the A4 Board" section of this manual.
Hardware adjustments must be made to the leveled sine and edge functions each time the
SC300 is repaired. In addition to the adjustment procedures, this section provides lists of
the required equipment and some recommendations on models that have the capabilities
required by these procedures. Equivalent models can be substituted if necessary.
