3. Setup
Before initial use, ensure you are in a carbon monoxide-free environment to allow the sensor to stabilize correctly.
- Powering On: Press and hold the Power/MUTE button for approximately 3 seconds to turn on the device. All alarm LEDs and display segments will activate. For Pro models, the unit will also vibrate.
- Warm-Up Sequence: The display will show a countdown from 10. This period allows the internal sensor to stabilize. Once the countdown completes and the display shows '0' ppm, the device is ready for operation.

4. Operating Instructions
The Sensorcon AV8 Inspector Pro features intuitive controls for daily use and configuration.
4.1. Basic Functions
- Power/MUTE Button:
- Long press (3 seconds): Powers the device on or off.
- Short press: Silences active alarms. An arrow above "MUTE" on the display indicates alarm silencing is active. Pressing again will re-enable alarms.
- MAX Button:
- Short press: Displays the highest CO reading detected since the last reset. This reading remains on the display until reset.
4.2. Menu Options (Pro Models)
To access the menu, press and hold both the Power/MUTE and MAX buttons simultaneously. Use the Power/MUTE button to navigate through options and the MAX button to select a desired setting.
- CAL (Calibration): Allows for performing calibration. This should only be done by authorized personnel.
- SET (Alarm Setpoints): Configures low and high alarm thresholds.
- TWA (Time-Weighted Average): Tracks 8-hour CO exposure over a 24-hour period.
4.3. Adjusting Alarm Setpoints
Within the SET menu option, use the MAX button to adjust alarm thresholds:
- Low Alarm Settings: Range from 5 to 100 ppm, adjustable in 1 ppm increments.
- High Alarm Settings: Range from 40 to 500 ppm, adjustable in 5 ppm increments.

5. Maintenance
Proper maintenance ensures the longevity and accuracy of your Sensorcon AV8 Inspector Pro.
- Battery Replacement: The device uses one Panasonic CR123A battery, providing over 2 years of continuous operation. Replace the battery when the low battery indicator appears on the display.
- Calibration: For continued accuracy, the device requires recalibration by authorized personnel approximately every 2 years. Contact Sensorcon support for calibration services.
- Cleaning: The IP67 rating means the device is water- and dust-resistant. Clean the exterior with a damp cloth. Do not use harsh chemicals or abrasive materials. Ensure the sensor inlet is clear of obstructions.
6. Troubleshooting
If your Sensorcon AV8 Inspector Pro exhibits unusual behavior or an alarm activates, consider the following:
- Alarm Activation: If visual, audible, or vibrating alarms activate, immediately move to an area with fresh air. Do not ignore CO alarms. Seek professional assistance to identify and resolve the source of carbon monoxide.
- No Display/Device Not Powering On: Check the battery. Ensure it is correctly installed and has sufficient charge. Replace if necessary.
- Inaccurate Readings: Ensure the device has completed its warm-up sequence. If readings remain inconsistent or appear inaccurate, the sensor may require recalibration.
- Defective Unit: If the device is defective upon arrival or malfunctions under normal use, contact Sensorcon customer support for assistance or replacement.
7. Safety Information: Carbon Monoxide Exposure Risks
Carbon monoxide (CO) is a colorless, odorless gas that can be deadly. Understanding exposure risks is crucial for safety.

| CO Concentration (PPM) | Potential Effects |
|---|---|
| 0 - 25 PPM | Normal fresh air. Maximum Time-Weighted Average (TWA) exposure for an 8-hour workday. |
| 100 - 400 PPM | Slight headache after 1-2 hours. Can become life-threatening in approximately 3 hours. |
| 800 - 1600 PPM | Dizziness and headache after 45 minutes. Dizziness in 20 minutes, potentially leading to death in 1 hour. |
Always prioritize safety and evacuate any area where CO levels are elevated.
