HAZARDOUS AREA WARNING:
designed to be intrinsically safe for use in areas classified as
hazardous locations. For your safety,
DO NOT use it in hazardous
(classified) locations.
CAUTION: Do not use flammable or combustible substances (like
carburetor fluid used for cleaning the probe) near an open flame.
When the instrument is used in an inefficient oil-fueled
appliance where there is a high emission of soot, the probe’s
sample filter may become clogged. Before every use check the
filter to confirm it is clean or replace it with a new filter.
To prevent soot intake and a clogged filter, a smoke test should be
performed before operating under such conditions. This ensures
that the furnace or boiler is burning at a level appropriate for the
use of this instrument.
When the CO
level exceeds the allowable threshold, a warning
2
will prompt the user to consider performing a smoke test. This
screen is cleared by pressing the ENTER 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.

The CO Protect feature protects the CO sensor from
the negative effects of being overloaded with CO gas.
Such negative effects include:
• a longer sensor recovery time
• a shortened sensor life.
The CO sensor is an electro-chemical sensor whose
lifespan is a function of its exposure to the target gas
(CO in this case). Though the CO sensor is designed to
be used in combustion environments having a fairly
wide range of CO gas present, limiting unnecessary
overexposure to CO gas can greatly increase the life
expectancy of the CO sensor. In addition, it can
shorten sensor recovery time after exposure.
The Protect CO feature sets a protection threshold
above which the analyzer’s pump shuts off, limiting the
CO sensor’s exposure to the high levels of CO gas and
its negative effects. Enter the Protect CO screen from
the Setup Menu. Select the “ON” option and press the
ENTER key. The CO threshold limit is displayed. Use

The instrument operator is able to easily replace the following components
without the use of tools:
• probe assembly
• probe filters
• batteries
• printer paper.
Additionally, a technician, with the use of readily available hand tools and
factory-provided instructions, can:
• perform basic diagnostics
• replace sensors
• confirm proper operation
before putting the unit back into service. Field calibration is also possible with
the proper equipment. Refer to the calibration section for more information.
5.2. Cleaning the Probe
The probe tube and gas sample hose will become dirty under normal use.
NOTE: The water trap’s filter element should prevent soot from
reaching the analyzer’s internal components. If the probe is not
kept clean, it could become clogged and restrict the flow of gas
into the analyzer, resulting in incorrect combustion test readings
and calculations.
NOTE:
requires less frequent cleaning than an analyzer used for testing

5.5. T-Stack Calibration
This procedure first zeroes and then spans stack temperature to known
temperature values.
The use of an electronic thermocouple simulator is the preferred method of
producing the desired calibration temperatures. Alternatively, ice and boiling
water baths can be used.
5.5.1. Materials Required
Thermocouple simulator (K-type)
•
Range: 0 to 600° F (-18 to 316° F)
Accuracy: ± 0.5° F (± 0.3° C)
(Alternatively) ice water, boiling water, thermometer

an Applied value that exactly equals the concentration stamped on the CO
cylinder.
NOTE: Bacharach recommends using a 500 ppm calibration gas,
however the calibration range is from 20 to 1,000 ppm. An attempt
to calibrate outside this range will cause the message “Applied
Value High” (or Low) to appear at the bottom of the screen.
3 Attach a 500 ppm CO cylinder to the regulator and connect calibration kit
components as shown below. Apply 500 ppm carbon monoxide in an air
balance calibration gas.
4 Wait until the Measured reading stabilizes and then press ENTER. The
message “Good Calibration” should briefly appear.
If the sensor’s output is low, but still usable, then the message “Good
Calibration WARNING Low Sensor” will appear. The sensor will now be
marked as being Low in the Warm-up screen.
