1.4 Product Overview
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
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 notications, 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.
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 specied 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

4.7 Dierential Temperature Measurement
In certain combustion applications, it may be desirable to have a dierential 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 dierential 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 dierential 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 dierential temperature measurement.

The instrument operator is able to easily replace the following components without the use
of tools:
• probe assembly
• probe lters
• batteries
• B-Smart® CO sensor
• printer paper.
Additionally, a technician, with the use of factory-provided instructions, can:
• perform basic diagnostics
• conrm 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.
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.
Follow the procedure below for CO sensor replacement.
1. Remove battery door and the connector tubing from the CO sensor.
2. Remove CO cap by twisting counter clockwise.
3. Gently pull CO sensor out of its socket.
4. Properly dispose of the old CO sensor.
5. Plug new CO sensor into its socket.
6. Install the CO cap by aligning it toward the “open” position (12 o’clock) as shown in
the diagram below, then twisting the cap clockwise approximately 40° to the “closed”
position (2 o’clock).
7. Reattach tubing.
8. Calibrate the CO sensor using either the standard calibration procedure or the B-Smart
procedure.
1. Enter the CALIBRATION MENU. Note that this requires password validation (see section
3.8).

NOTE: If the correct code was entered, the analyzer accepts it and returns
to the CALIBRATION MENU. If an incorrect code was entered, the screen will
display “Invalid Code.” Check to make sure the correct code has been entered
If the problem persists, contact your nearest Bacharach Service Provider.
NOTE: B-Smart® codes can be entered through the Fyrite® User Software (FUS)
NOTE: Installing a B-Smart® sensor forces the instrument to perform a zero
function (either manual or automatic)
NOTE: Bacharach oers a convenient Exchange Program (where available) that
allows the customer to regularly receive pre-calibrated replacement sensors that
include a code that can be entered into the analyzer for a quick convenient setup.
Contact Bacharach customer service for more details about this program.
This procedure rst zeroes and then spans the temperature channel 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)
4. Set thermocouple simulator to 32° F (0° C), and then use the UP ( ) and DOWN ( ), LEFT
(
) and RIGHT ( ) arrow buttons to enter an Applied value that exactly equals the setting
of the simulator.
Alternatively: Submerge probe tip into an ice-water bath with a thermometer, wait several
minutes, and then use the UP (
exactly equals the thermometer reading.
NOTE: The calibration range is from 32 to 41° F (0 to 5° C). An attempt to
calibrate outside this range will cause the message “Applied Value High” (or Low) to appear at the bottom of the screen.
5. Wait until the Measured reading stabilizes, and then press ENTER to calibrate the TS-Zero
Measured value to that of the Applied value, after which the message “Good Calibration”
should briey appear followed by the CALIBRATE TS-SPAN screen.

6. Set thermocouple simulator to 572° F (300° C), and then use the UP (
) and DOWN ( ),
LEFT ( ) and RIGHT ( ) arrow buttons to enter an Applied value that exactly equals the
setting of the simulator.

Alternatively: Submerge probe tip into a container of boiling water with a thermometer, wait
several minutes, and then use the arrow buttons to enter an Applied value that exactly equals
the thermometer reading.
NOTE: The calibration range is from 175 to 625° F (80 to 329° C). An attempt
to calibrate outside this range will cause the message “Applied Value High” (or Low) to appear at the bottom of the screen.
7. Wait until the Measured reading stabilizes, and then press ENTER to calibrate the TS-Span
Measured value to that of the “Applied” value, after which the message “Good Calibration”
should briey appear followed by the CALIBRATION menu being re-displayed.
The CO zeroing process is done automatically during warm-up or manually using the
manual zero feature. To perform a manual zero, follow the steps below. If your instrument
is congured for CO auto zero, then skip this CO manual zero procedure and go to the CO
Sensor Span procedure that follows.
1. If not already done, turn ON the analyzer and display the Main Menu screen.
2. Use the UP (
3. From the Setup Menu, use the UP (

NOTE: Bacharach recommends using a 500 ppm calibration gas, however the
calibration range is from 100 - 5,000 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.
Low Sensor COCO sensor output was low but still usable. Sensor may need to be replaced in the
near future.
Low BatteryBattery voltage is low. Replace the batteries.
Applied Value High / LowAn attempt was made to calibrate a sensor outside its range—either above (High)
or below (Low) the acceptable range.
Warm-up Sensor Error• CO sensor was not zeroed at warm-up because of high output. Run instrument
on fresh air then restart instrument to re-zero sensor. If the message persists,
the CO sensor may need to be replaced.
• Temperature sensors are measuring temperature outside the range of -4° to
212° F at warm-up. Make sure that the thermocouple is sampling ambient
room air within the temperature range at warm-up.
• Messages will indicate which sensors are in error.
Set ClockTime and date values need to be set in the instrument.
OVROccurs in the number elds of sensors that have achieved over-range condition.
***Occurs in the number elds of sensors. Replaces in-error sensor values and any
calculated values that depend on those sensor values.
---Occurs in the number elds of sensors and indicates that values were not calculated.
NOTE: If a particular sensor is in error during warm-up, the instrument automatically
displays the error. The instrument continues to operate with the sensor in error, however
information dependent on the sensor in error is not displayed.
