CALIBRATION RECORD AND INDEX
This abridged Calibration Procedure is provided to aid
in checking the operation of the Type 503. It may be used
as a calibration guide by the experienced calibrator, or it
may be used os a calibration record. Since the slop numbers
and titles correspond to those used in the complete Calibra
tion Procedure, the following procedure serves as an index
to locate a step in the complete Calibration Procedure.
Characteristics are those listed in the Characteristics section
of the Instruction Manual.
Type 503 Serial No.
