5. Setup
Follow these steps for initial setup of your FD-600-CO2 analyzer:
- Charging the Device: Connect the USB charging cable to the analyzer's USB port and a suitable power source. The battery indicator on the display will show charging status. Ensure the device is fully charged before first use.
- Attaching the Probe: Connect the tubing from the telescopic probe to the air inlet barb connector on the top of the analyzer. Ensure a secure fit to prevent air leaks.
- Powering On: Press and hold the ON/OFF button until the display illuminates. The device will perform a self-test before entering measurement mode.
6. Operating Instructions
The FD-600-CO2 analyzer is designed for straightforward operation. The built-in pump actively draws air samples through the probe for analysis.
- Measurement Mode: Once powered on, the device will display the current CO2 concentration. The NDIR sensor provides accurate readings.
- Using the Telescopic Probe: Extend the telescopic probe to the desired length to reach the sampling area. Position the probe's tip to draw air from the target location. The built-in pump will pull the sample through the tubing to the analyzer.
- Display Information: The color display shows CO2 concentration (in %VOL or PPM), battery status, and other relevant information. Use the navigation buttons to access different functions or view historical data graphs.
- Alarms: The device features bright LED, buzzer, and vibration alarms to alert users to high CO2 levels. Alarm thresholds can typically be configured in the device settings.
