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.
