STANDARDS AND TOLERANCES
4.1 INTRODUCTION
is a list of equipment parameters, their standards, and their limits. In the Parameter column, each
parameter measured or adjusted is listed. The paragraphs of
used to establish the values of the parameters are listed in the Reference Paragraph column. In the Standard column
are listed the optimum values of the parameters. The Initial Tolerance column is the maximum possible deviation,
above or below the standard value, when the DVOR equipment is commissioned initially or subsequent to any
modification. The Operating Tolerance column is the possible deviation, above or below the standard value, when
the DVOR equipment is in operation after the completion of commissioning activities.
