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 instructionsabove anything mentioned in this manual.

• Before inserting the probe in the flue, 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 flue is often a good place to locate the sensing point of the probe, but locating it at the highest point of CO is best.

Operation

The CAT85 workflow 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 seals the sensors when powering off 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, flue 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 difficulty charging or using when connected, try a shorter cable or a USB port/adapter with higher-rated amps.

Powering ON
Read the “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 the start countdown to complete.

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

Allow the timer to count down before turning ON/OFF again.

Powering OFF
Read the “Safety Information” section.

1. Complete your testing and reporting.

2. Move probe to fresh ambient air to clear CAT85 of hot flue 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 off when SEALED and purging is complete.
   Press deeper if it displays “UNSEALED.”

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

Storage
Read the “Safety Information” section.

• Ensure the probe has cooled to ambient temperature before inserting it into the 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.
• The warmup is extended if freezing temperatures are detected, but it’s best to store it at room temperature.

Job Menu

The JOB MENU is the heart of CAT85 Each job has its own list of saved tests After saving your tests, view them directly in the Job Link® mobile app, or send your report to a model CATPR wireless thermal printer SAVE AND EXIT when your 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 the startup is complete. This test analyzes flue gas from various heating equipment. Use this test to set up, test, and document equipment performance.

Read the “Safety Information” section.

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

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

3. Twist the probe cone lock into the flue port at the sampling point and secure the probe. See the “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 flue, where you find the highest level of CO.

7. SAVE ALL measurements displayed.

8. Remove the probe and cone from the flue when finished.
   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 flue 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 off if you see this warning. It appears that the CO sensor detects a potentially damaging level of CO. Remove the probe from the flue so fresh ambient air can pump through the device.
Trending
Use trending to check how combustion parameters change over time. See the “Settings” section for TRENDING SETUP.

Ambient CO
CO is a very dangerous gas and it’s critical that living spaces are clear of carbon monoxide.

Read the “Safety Information” section.

1. Ensure startup is complete. See the “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 immediately 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 the “Safety Information” section.

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

2. Select DRAFTS from the JOB MENU.

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