PROCEDURE
General
The follow ing procedure is arranged so the Type 310A
can be calibrated w ith the least interaction o f adjustments
and reconnection o f equipment. A picutre o f the test equip­
ment required fo r each group o f steps is given to aid in
identification o f the necessary equipment. Control settings
and test equipment setup throughout the procedure
continue from the preceding step(s) unless noted otherwise.
A complete list o f control settings is given following this
picture. To aid in performing a complete calibration pro­
cedure controls must be changed fo r the next step are
printed in bold type.
NOTE
Control titles which are printed on the front-, side- or
rear-panel o f the Type 310A are capitalized in this
procedure (e.g., VO LTS/D IV). Internal adjustments
are initial capitalized only (e.g.. Vert Gain Adj).
