1.3 General Safety Statements

WARNING: This analyzer is not intended to be used as a safety device.

WARNING: When testing a combustion system, a full visual inspection should be

performed to ensure its safe operation.

CAUTION: This analyzer is not intended to be used on a continuous basis.

CAUTION: Do not store instrument or its sensors with solvents or products that

contain solvents.

CAUTION: Except for sensor and battery replacement, this analyzer should only be
opened and/or serviced by authorized Bacharach personnel. Failure to comply may
void the warranty.

HAZARDOUS AREA WARNING: This instrument has not been designed to be

intrinsically safe for use in areas classied as hazardous locations. For your safety, DO
NOT use it in hazardous (classied) locations.

CAUTION: Do not use ammable or combustible substances (like carburetor uid used
for cleaning the probe) near an open ame.

CAUTION: When the instrument is used in an inecient oil-fueled appliance where
there is a high emission of soot, the probe’s sample lter may become clogged. Before
every use check the lter to conrm it is clean or replace it with a new lter.

The Monoxor® XR is a portable hand-held carbon monoxide (CO) analyzer for use in
commercial and industrial applications. It is intended to be used by:

• Engine & service technicians

• Maintenance personnel

• Safety inspectors

• Propane forklift operators

to detect and display concentrations of CO gas between 0 and 80,000 ppm. The analyzer is
capable of testing for CO in both ambient room air and in the exhaust stream of fossil-fuel

red combustion systems.

Ambient CO

CO gas is colorless, odorless, and deadly. Test CO levels in suspect Pambient air. Perform
an automated 15-minute test, watch live values, or view a dynamic CO graph over time.

Fig. 1-1: Perform an Ambient CO test and watch live values, or view a dynamic CO graph over
time

The analyzer detects and displays the presence of CO by rst drawing in a gas sample from

the area being tested by the analyzer’s built-in motorized pump. The gas sample is next
directed into a sensor chamber where the sample is analyzed for the presence of CO. If
CO is detected, the CO ppm level is given on the analyzer’s main display. A trending screen
(accessible from the RUN screen by using the right or left arrow key) shows dynamic CO levels
graphed over a programmable time period (from 30 seconds to 15 minutes). In addition to the

visual notications, you can set a CO alarm limit, above which an audible alarm buzzer will

beep repeatedly. An audible alarm with a slower beep frequency occurs when the batteries
are low.

A backlight enables the operator to read the display in dimly-lit areas. The displays and
menus are available in multiple languages (English, French and Spanish).

A permanent record of the detected CO level, along with the current time and date, can be
made by using the optional wireless IrDA printer. Test records can also be saved in memory.

Monoxor® XR User Manual

An ambient CO feature takes approximately 15-minutes to complete and provides a minute­by-minute snapshot of CO readings, as well as a “Max CO” value that represents the highest
CO reading measured during the entire test. Results can be saved to memory and/or printed.

A calibration reminder can be set to occur every 6, 8, 10, 12, or 15-months after the last
calibration. (Select “Never” to disable this feature.) Regular calibration periods of 6 months to 1
year are recommended. The calibration reminder value sets a time period after which the
analyzer displays a calibration reminder message during warm-up.

To avoid the need for manual CO sensor calibrations, the B-Smart® Sensor program is
supported with the Monoxor

A programmable inactivity timeout causes the analyzer to initiate shutdown mode if no key

presses occur for the specied time period. If the analyzer initiates automatic shutdown or

is turned OFF manually while a high level of CO is still present within the unit, the automatic
CO purge feature forces the analyzer’s pump to remain on until the detected CO level drops
below 50 ppm.

The instrument is supplied with the following components:

• Probe and hose assembly

• Four disposable “AA” alkaline batteries

• Hard carrying case

• Factory-calibrated and installed CO sensor

Depending on the model and kit, some or all of the following components are included:

• Spare lters

• Fyrite

®

User Software (FUS)

• USB cable (type A to mini B)

• Infrared Data Association (IrDA) printer with four disposable “AA” alkaline batteries

• Printer paper

Using the optional thermocouples, ambient and ue gas temperatures can be measured.

Additionally, the Monoxor® XR can calculate a dierential temperature based on two
sampled temperatures (T1 and T2) using the optional stack thermocouple or optional probe
assembly (with built-in thermocouple). After you take the two sample readings, the dierential
value (T1-T2) is calculated, optionally saved in memory, displayed on the main run screen,
and is shown on printouts.

4.6 Ending a Test

WARNING: Burn Hazard. Do not touch the probe after removing it from a ue.

Allow the probe to cool before handling (about 5 minutes).

After taking a gas sample, remove the probe and take the analyzer to an area containing
fresh air. Allow the pump to run until the CO reading drops to near zero.

4.7 Dierential Temperature Measurement

In certain combustion applications, it may be desirable to have a dierential temperature
measurement. Use the Di Temp menu and either the optional probe assembly with

thermocouple (P/N 0019-7111), or one of the optional K-Type thermocouples (P/N 0104-1798
or P/N 0104-1797) to accomplish this task.

The Monoxor® XR calculates the dierential temperature based on two sampled
temperatures (T1 and T2) which it reads from the optional probe assembly’s thermocouple
(which is connected to the T-STACK connector of the instrument). After you take the two

sample readings, the dierential value (T1-T2) is calculated, optionally saved in memory,

displayed on the main run screen, and is shown on printouts. Use the following procedure

to perform a dierential temperature measurement.

Example Procedure for Taking Dierential Temperature Measurements

1. Attach the thermocouple plug of the optional probe assembly to the T-STACK connector

®

on the bottom of the Monoxor

From the Main Menu, select the Di Temp option. When this option is rst selected, the

current temperature (Temp) is displayed. Values for T1 and T2 will show no readings until

they are saved by the operator, after which a dierential value (T1-T2) will also be displayed.

memory so that it can be retrieved and/or printed later.

8. Carefully remove the probe assembly and allow it to cool.

NOTE: A negative dierential value will be displayed if T1<T2.

4.8 Timed Ambient CO Testing

This procedure takes approximately 15 minutes to complete and provides a minute-by­minute snapshot of CO readings, as well as a “Max CO” value that represents the highest
CO reading measured during the entire 15-minute test. Results can be saved to memory
and/or printed.

Example Procedure for Taking Ambient CO Measurements

5.2 Cleaning the Probe

The probe tube and gas sample hose will become dirty under normal use.

NOTE: The lter 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 ow of gas into the analyzer, resulting in incorrect test readings.

NOTE: An analyzer that tests natural gas furnaces normally requires less

frequent cleaning than an analyzer used for testing coal- or oil-red furnaces.

5.2.1 Equipment Required

• Alcohol

• Aerosol Can of Automotive Carburetor Cleaner

• Clean Rag

• Source of Compressed Air (optional)

CAUTION: Do not use ammable or combustible substances (like carburetor
uid used for cleaning the probe) near an open ame.

5.2.2 Procedure

1. Remove gas sample hose from the disposable lter assembly.

CAUTION: Carburetor cleaner damages plastic components. Take precautions
not to spray cleaner onto the probe handle or analyzer.

2. Insert the plastic spray tube of the carburetor cleaner into the gas sample hose, and then
liberally spray carburetor cleaner through the hose and out the probe tube.

3. After spraying, remove all the residual cleaner by repeatedly ushing the gas hose and
probe tube with alcohol.

4. Wipe o the surfaces of the probe and tubing with a clean cloth.

5. Allow the parts to dry completely. If available, blow compressed air through the probe
to expedite the drying process.

6. Reconnect gas sample hose to the disposable lter assembly.
