Except for sensor and battery replacement, this

HAZARDOUS AREA WARNING: This instrument has not been
designed to be intrinsic
ally safe for use in areas classified as
hazardous locations. For your safety, DO NOT use it in hazardous
(classified) locations.
CAUTION: When the instrument is used in an inefficient furnace or
boiler application where there is a high emission of soot, the probe’s
sample filter may become clogged. Before every use check the filter
to confirm that it is clean or replace it with a new filter.
To prevent this from occurring, a smoke test should be performed
before operating under such conditions. Thi
s ensures that the
furnace or boiler is burning at a level appropriate for the use of this
instrument.
When the CO
2
level exceeds the allowable threshold, a warning will
appear prompting the user to consider performing a smoke test (see
Figure 1-1
). This screen is removed by pressing the ENT button.
Once the warning is cleared, it will not be displayed again for that
particular test. If a new test is started (by pressing the HOLD
button), the warning will be displayed again if the limit has been
exceeded.
