Hours of Operation
Monday through Friday: 8am to 4pm
Note: East Coast Time Zone
Warranty
Each AV8 Inspector comes standard with a two year warranty on all of its
parts. It is recommended that
you calibrate the AV8 Inspector every six months to ensure the best accuracy
possible. An EOL (End of Life) symbol will display on the LCD after two years
of use. A successful calibration will remove the EOL notification for an
additional 180 days. Future successful calibrations can continue to be done as
long as the electrochemical sensing element remains in good condition.
Maximum Operating Conditions
Temperature: -20°C to +50°C (-4°F to +122°F) Humidity: 20-90% R.H. (0-99% intermittent)
Practical Considerations
Short-term measurements (i.e. <1hr) in any humidity (0-99% R.H.) are fine as
long as condensation does not block the sensor inlet. Longer term exposure to
extreme humidity or temperature outside the specified range can result in
damage to the sensor. Please note that the LCD display and sensor will not
function properly at colder temperatures outside of the specified operating
range.
NOTE: Exposure to higher temperatures and humidity can damage the device.
AV8 Inspector Features Comparison
Mounting Bracket
AV8 Inspectors come with a mounting bracket that allow it to be mounted to the Instrument panel or other location in the aircraft. Four screws or bolts are required to mount the AV8 bracket. Since mounting locations and scenarios will vary greatly, mounting hardware is not included.

Operating Instructions
-
Turning on the AV8 Inspector
Hold POWER/MUTE for 1 to 2 seconds to turn on. A 10 second count down timer allows the sensor to warm up before displaying real-time readings. -
Muting audible alarms
If an alarm occurs and you want to mute the sound, briefly press the POWER/MUTE button. -
Shutting off the AV8 Inspector
Simply hold POWER/MUTE for 3 seconds to turn the device off. A count down from 3 will be displayed while you are shutting off the AV8 Inspector. -
Turning on MAX mode
To enable MAX mode, briefly press the MAX button. MAX mode will only show the highest, peak reading encountered by the AV8 Inspector while the MAX mode is active. The display will only show another value once a new, higher reading is encountered.
Advanced Operating Instructions
-
Entering the advanced features menus
Press the POWER/MUTE and MAX buttons at the same time for 5 seconds to access the advanced features series of menus. Only CAL mode is available for the AV8 Inspector, while the AV8 Inspector Pro will have four advanced features (TWA, CAL mode, Lo Alarm SEt mode and Hi Alarm SEt mode). To exit, press POWER/MUTE as many times as required to exit.’ -
Viewing TWA readings (AV8 Inspector Pro Only)
Press the POWER/MUTE and MAX buttons at the same time for 5 seconds to access the TWA screen which displays the maximum 8 hour exposure during the last 24 hours. To exit, press POWER/MUTE as many times as needed to exit. -
Adjusting the Lo Alarm (AV8 Inspector Pro Only)
Press the POWER/MUTE and MAX buttons at the same time for 5 seconds to access the advanced features series of menus. Press POWER/MUTE twice to get to the Lo Alarm SEt screen.
Push or push and hold the MAX button to adjust the Lo Alarm to a setting from 5 to 100ppm CO. Press POWER/MUTE as many times as needed to exit. -
Adjusting the Hi Alarm (AV8 Inspector Pro Only)
Press the POWER/MUTE and MAX buttons at the same time for 5 seconds to access the advanced features series of menus. Press POWER/MUTE thrice to get to the Hi Alarm SEt screen. Push or push and hold the MAX button to adjust the Hi Alarm to a setting from 40 to 500ppm CO. Press POWER/MUTE as many times as needed to exit.
Calibration Instructions for the AV8 Inspector
Calibration is done at the factory or by the customer using a gas regulator, some Tygon tubing and 50ppm CO calibration gas. Go to https://sensorcon.com or call us at 1-716-276-2975 for more info.
Follow these steps below to calibrate the AV8 Inspector:
-
Entering CAL mode
Press the POWER/MUTE and MAX buttons at the same time for 5 seconds to access the CAL screen. -
Performing the ZERO cal
In a clean air environment, press the MAX button to begin ZERO calibration. A 30 second countdown timer will be displayed while zero calibration is being done. Once complete, the sensor will beep, quickly flash CAL dn and then quickly flash the BASELINE value just before continuously displaying the word GAS. If you want to continue on with the GAS calibration, skip to step 3. If you only want to perform ZERO cal and not the gas calibration, press POWER/MUTE to exit. no CAL will flash on the screen before returning to normal operation.
Note: ZERO cal in a non-clean environment will cause errors in the readings! -
Performing GAS cal
When ZERO cal is complete, use 1/4” OD, 1/8” ID Tygon tubing to attach the cal gas cylinder and regulator to the sensor inlet. Turn on the gas flow (rate of 0.3 to 0.5L/min). Press the MAX button to start the GAS cal process. A timer will countdown from 60 seconds. Once the countdown has finished, the sensor will beep, quickly flash CAL dn and then display the SENSITIVITY for 2 seconds before returning to normal operation. If there is an issue with the sensor calibration, the sensor will display err before returning to normal operation. If the sensor displayed err during calibration, please contact Sensorcon for further support.
Note: Do not service this device in a hazardous environment.
Calibration Instructions for the AV8 Inspector Pro:
-
Entering CAL mode
Press the POWER/MUTE and MAX buttons at the same time for 5 seconds to access the advanced features series of menus. Press POWER/MUTE once to get to the CAL screen. -
Performing the ZERO cal
In a clean air environment, press the MAX button to begin ZERO calibration. A 30 second countdown timer will be displayed while zero calibration is being done. Once complete, the sensor will beep, quickly flash CAL dn and then will show the BASELINE value. Pressing the MAX button will advance to the next screen displaying the word GAS. If you want to continue on with the GAS calibration, skip to step 3. If you only want to perform ZERO cal and not the gas calibration, press POWER/MUTE to exit. no CAL will flash on the screen before returning to the next advanced features series of menus. To return to normal operation, press POWER/MUTE two more times to exit.
Note: ZERO cal in a non-clean environment will cause errors in the readings! -
Performing GAS cal
When ZERO cal is complete, use 1/4” OD, 1/8” ID Tygon tubing to attach the cal gas cylinder and regulator to the sensor inlet. Turn on the gas flow (rate of 0.3 to 0.5L/min). Press the MAX button to start the GAS cal process. A timer will countdown from 60 seconds. Once the countdown has finished, the sensor will beep, quickly flash CAL dn and then display the SENSITIVITY for 2 seconds before returning to normal operation. If there is an issue with the sensor calibration, the sensor will display err before returning to normal operation. If the sensor displayed err during calibration, please contact Sensorcon for further support.
