SINGLE STREAM PROGRAMMING

In normal operation (Operating Pages 0 and 1) the display
gives indication of the units of measurement, diagnostics,
calibration information and time. Selection is made by means
of the 

 and 

 switches.

Operation of the 

  switch enables a series of 'programming'

pages to be displayed. Unauthorized entries to these pages
are inhibited by a four-digit security code which is displayed
immediately after the page header.

Values displayed in Operating Pages 0 and 1 are for viewing
only and cannot be altered by the operator.  Displayed values
on subsequent pages indicated by x's can be altered by means
of the 

 and 

 switches. Options such as Yes/No or High/

Low are also selected using these switches. Passing onto the
next parameter, or exiting from the page, automatically enters
the new value into memory.

Programming information for users of multi-stream monitors is
contained in Appendix A.
