The unit number flag is used to identify the
monitor on a RS-485 network, if that option
has been purchased. This flag is set to 1
by default.
Press the “ENT” key to move the cursor to
the next entry. When all entries have been
viewed, press the “ENT” key again to

The slope flag is used for circumstances
where an individual zone might be exposed
to large levels of refrigerant. This flag will
hold the monitor in its current mode,
whether it be autosample or autozero, if the
raw measurement has not leveled off to a
constant measurement.
For instance, after
an extremely large level of refrigerant has
been measured, the monitor might run in
autozero longer than expected if the
measured level is still falling.
Set this flag
to the factory default of 50 if no large levels
are expected. Set this flag lower if large
levels are expected.
Press the “ENT” key to move the cursor to
the TWA ALARM flag. This flag is reserved
for
future
implementation
of
TWA
measurement. This flag should be left at
the factory default of 0.
Press the “ENT” key to move the cursor to
the FULL SCALE flag. This flag is used to
adjust the full scale measurement for the
analog output. The factory default is 1000,
meaning that the 0-10 volt analog output
corresponds to 0-1000 ppm. This flag
should be left at the factory default unless a
custom measurement range has been
implemented in the monitor. Consult
factory
technical
support
for
further
information if needed.
Press the “ENT” key to move the cursor to
the TWA refresh flag. This flag is used to
save peak ppm measurements if Trending
is not implemented. A TWA refresh rate of
5 minutes corresponds to a theoretical ten-
hour time weighted average (5 minute
refresh rate times 120 saved data points
yields ten-hour average). As with the TWA
ALARM flag, this feature is not yet
implemented.
Press the “ENT” key to move the cursor to
the next entry. When all entries have been
viewed, press the “ENT” key again to
display the third system flag screen.
The DELAY FLAGS are used to implement
an additional time delay, in minutes before
energizing the respective alarm relays.
This time delay is similar to the LEAK
WAIT, except that the user is able to create
a time definite delay, rather than the ppm
level defined LEAK WAIT delay. The
factory default setting is 0 for each delay.
Press the “ENT” key to move the cursor to
the next entry. Once the DELAY entries
have been viewed, press the “ENT” key to
move the cursor to the LATCH FLAG. The
LATCH FLAG is used to determine if the
