CALIBRATION PROCEDURE
The following procedure is arranged so that the 7A19
can be calibrated with the least interaction of adjustments
and re-connection of equipment . The control settings and
test equipment setup throughout this procedure continue
from the preceding step(s) unless otherwise noted. Refer to
Fig. 5-1 for location of adjustments .
