Common Sampling Points

The many types of combustion equipment vary

in their design and therefore their ideal sampling

points. However, there are commonalities that

make for useful guidelines when analyzing

performance.

Heed equipment manufacturer instructions

above anything mentioned in this manual.

• Before inserting the probe in the ue, it’s good

practice to test for excessive soot which may

lead to carbon buildup within the analyzer or

overexpose sensors.

• Use the probe cone lock to hold the

probe tightly in place at the sampling

point.

• The center of the ue is often a

good place to locate the sensing

point of the probe, but locating

at the highest point of CO is best.

1312

Operation

The CAT85 workow is streamlined to quickly

get into your job, complete your testing, send

your report, and get onto your next job.

SensorVault™ Technology

The SensorVault™ technology of the power

button unseals sensors when powering on and

and seals the sensors when powering o. This

requires a bit more force than most other buttons

so be sure to press fully. You’ll hear a“click”.

HydroCycle™ Pump

The CAT85 does not have a water trap. Instead,

ue gas condensate is automatically pumped

back out of the front of the probe at a regular

interval. Point the probe downwards as you

remove it to empty any remaining condensate

before storing.

Battery Charging

Charge the batteries with the USB-C cable

connected to any USB charging port/adapter

rated at 5V/2A DC. CAT85 can be operated while

charging. If you have diculty charging or using

when connected, try a shorter cable or a USB

port/adapter with higher rated amps.

Powering ON

Read “Safety Information” section.

1. Push the probe cable connector into the bottom of CAT85.

2. Move probe to fresh ambient air for accurate sensor zeroing.

• This step should be executed outside of the test room and away

from any vehicle exhaust where traces of CO could be lingering.

• Do not rely on the analyzer alone to check for unsafe CO levels.

3. Fully press the power button down until you feel and hear the

“click”of the SensorVault™ technology UNSEAL the sensors.

Press deeper if it displays “SEALED”.

4. Wait for start countdown to complete.

5. Start testing. See “Job Menu” section.

Powering OFF

Read “Safety Information” section.

1. Complete your testing and reporting.

2. Move probe to fresh ambient air to

clear CAT85 of hot ue gas.

3. Fully press the power button down until you feel and hear the

“click”of the SensorVault™ technology seal the sensors.

The unit powers o when SEALED and purging is complete.

Press deeper if it displays “UNSEALED.”

4. Store safely. See “Storage” section below.

Storage

Read “Safety Information” section.

• Ensure the probe has cooled to ambient temperature before

inserting into its protective sleeve of the carrying case.

• Insert the CAT85 body upside down into the padded pocket so

the display is fully covered and the cable is free to move.

• Do not stack objects on top of the case.

• Warmup is extended if freezing temperatures are detected, but

it’s best to store at room temperature.

Allow the timer

to count down

before turning

ON/OFF again.

Job Menu

The JOB MENU is the heart of CAT85. Each job

has its own list of saved tests. After saving your

tests, view directly in the Job Link® mobile app

or send your report to a model CATPR wireless

thermal printer. SAVE AND EXIT when you’re

ready for your next job. Jobs are automatically

numbered sequentially. Open the JOB ARCHIVE

to view, continue, or delete jobs.

Combustion

By default, the COMBUSTION test starts automatically after

startup is complete. This test analyzes ue gas from various heating

equipment. Use this test to setup, test, and document equipment

performance.

Read “Safety Information” section.

1. Ensure startup is complete. See “Powering On” section.

2. Mount the CAT85 onto a secure, cool, magnetic surface near the

sampling point.

3. Twist probe cone lock into the ue port at the sampling point and

secure the probe. See “Common Sampling Points” section.

4. Select COMBUSTION from the JOB MENU.

5. Select the fuel and equipment type.

6. View live measurements.

For best results, test for at least 5 minutes near the center of the

ue, where you nd the highest level of CO.

7. SAVE ALL measurements displayed.

8. Remove the probe and cone from the ue when nished.

Be careful not to let the metal touch anything until it cools.

Reference Ranges

When selecting equipment, the reference range icon shows when

available. Temperature, O2, CO, and CO air free all have reference

ranges.These ranges show the generally accepted ranges for the

chosen equipment type. The arrow is GREEN if within the reference

range and YELLOW if not. These ranges are for reference only.

ZERO PROBE

ZERO PROBE sets the pressure sensor to 0 and resets the oxygen

zero point. Always remove the probe from the ue before using ZERO

PROBE. For the very best O2 measurements, start the pump and keep

the probe in ambient air for 2 minutes before using ZERO PROBE.

CO Sensor Overexposure

Do not power o if you see this warning. It appears if the CO sensor

detects a potentially damaging level of CO. Remove the probe from the

ue so fresh ambient air can pump through the device.

Trending

Use trending to check how combustion parameters change over

time. See “Settings” section for TRENDING SETUP.

1716

Ambient CO

CO is a very dangerous gas and it’s critical that living spaces are

clear of carbon monoxide.

Read “Safety Information” section.

1. Ensure startup is complete. See “Powering On” section.

2. Select AMBIENT CO from the JOB MENU.

3. View CO measurement while walking through the living space.

4. SAVE the measurement displayed.

“DELETE” temporarily deletes a single value so you can retest.

“DELETE TEST” deletes the test.

Ambient CO Warning

Vacate the area immediatly if you see the Ambient CO warning. It

appears if the CO sensor detects a harmful level of CO. The CO warning

level can be adjusted from the warning screen.

Drafts

CAT85 saves live draft pressure with the COMBUSTION test, but a

saved FLUE DRAFT measurement overrides this value. Draft pressure

measurement is important for safety and performance.The probe

pressure sensor is used for all three drafts.

Read “Safety Information” section.

1. Ensure startup is complete. See “Powering On” section.

2. Select DRAFTS from the JOB MENU.

3. Mount the CAT85 onto a secure, cool, magnetic surface near the

sampling point.

4. ZERO PROBE to zero the probe’s pressure sensor.

Always remove the probe from the ue before using ZERO PROBE.

5. Move probe to desired sampling point- DILUTED, FLUE, or

OVERFIRE.

6. View live measurement.

7. SAVE the measurement displayed.

“DELETE” temporarily deletes a single value so you can retest.

“DELETE TEST” deletes the test.

8. Remove the probe from the sampling point when nished.

Be careful not to let the metal touch anything until it cools.

1918

Primary Air

Primary air temperature is measured during startup and is used for

the COMBUSTION test. This is the temperature of the air going into the

combustion equipment. It’s sometimes useful to set it after startup if

the ambient temperature changes. You can enter it manually or use the

probe’s temperature sensor.

Read “Safety Information” section.

1. Ensure startup is complete. See “Powering On” section.

2. Select PRIMARY AIR from the JOB MENU.

3. Move the probe to the entry point of air into the combustion

equipment.

4. View live measurement or use the keyboard onscreen to

manually enter a value.

5. SAVE the temperature.

“DELETE” temporarily deletes a single value so you can retest.

“DELETE TEST” deletes the test.

Smoke

The smoke test is used to document the soot levels within the ue.

This is good practice when“dirty”combustion is expected in order to

extend the life of CAT85 and equipment. A third party smoke tester is

needed.

Read “Safety Information” section.

1. Ensure startup is complete. See “Powering On” section.

2. Select SMOKE from the JOB MENU.

3. Use your smoke tester to nd the smoke level.

4. Select the corresponding level on screen.

5. SAVE the smoke level.

“DELETE” deletes the entry.

Fuel Pressures

CAT85 has P1 and P2 pressure ports for connecting hoses (not

included) to gaseous fuel sources/regulators. Do not test liquid fuels.

This is very similar to the Manometer test, but uses fuel-centric labels

that aid in reporting.

Read “Safety Information” section.

1. Ensure startup is complete. See “Powering On” section.

2. Shut o main gas supply power to equipment.

3. Mount the CAT85 onto a secure, cool, magnetic surface near the

test point(s).

4. Connect a static pressure hose to P1 to measure INLET pressure.

Connect astatic pressure hose to P2 to measure OUTLET pressure.

An additional OUTLET pressure is available for two stage systems.

5. Select FUEL PRESSURES from the JOB MENU.

6. ZERO each pressure port sensor, P1 and P2 before connecting to

fuel source. Ensure there are no kinks in the hose.

7. Connect hose(s) to INLET and/or OUTLET.

8. View live measurements.

9. SAVE any measurement displayed.

“DELETE” temporarily deletes a single value so you can retest.

“DELETE TEST” deletes the test.
