6. Calibration

Zero calibration and Span calibration are crucial for maintaining the accuracy of your gas detector. These steps require rigorous operating conditions and should be performed by qualified professionals using necessary accessories and standard gas.

6.1 Zero Calibration

Zero calibration is performed when the reading drift is too large after stabilization, or when an alarm occurs. This ensures the device accurately reads zero concentration in a clean air environment.

1. From the main menu, select "Calibrate zero" and press the ON/OFF button.
2. You will be prompted to enter a password. Please contact ATO support for the password.
3. Follow the on-screen instructions to expose the sensor to clean air and confirm the zero calibration.

6.2 Span Calibration

Span calibration (also known as target point calibration) involves applying a standard gas of a specific known concentration to the sensor without atmospheric dilution. The calibration result should match the concentration of the standard gas.

1. From the main menu, select "Calibrate span" and press the ON/OFF button.
2. You will be prompted to enter a password. Please contact ATO support for the password.
3. Connect the device to a standard gas source with a known concentration using appropriate regulators and flowmeters.
4. Follow the on-screen instructions to apply the standard gas and confirm the span calibration.

The detector must be calibrated regularly to ensure accuracy and reliability, especially before entering detection areas.

8. Troubleshooting

If you encounter any issues with your ATO Portable Ozone Gas Detector, please refer to the following common troubleshooting steps:

• Device not powering on: Ensure the battery is charged. Connect the device to the charger and try again.
• Inaccurate readings: Perform a zero and span calibration in a controlled environment. Ensure the sensor is clean and unobstructed.
• Continuous alarm: Check the alarm point settings. If the alarm persists in a clean environment, perform a zero calibration or restore factory settings (requires password).
• Data transfer issues: Ensure the USB cable is securely connected to both the device and the computer. Check for any driver installations required by your operating system.
• Screen display issues: Adjust the gray level setting for better visibility. If the issue persists, contact support.
