Operation
The CAT85 workow 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 diculty 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.
