DM509C supports data store and download to PC. Operation steps as below:
Step1: Download the CO2 Sensor.zip through the link: https://www.alcohol-tester.co/dm509.zip.
Step 2: Unzip the CO2 Sensor.zip to the same folder.
Step 3: Based on your Windows version, select the appropriate installation file.
Step 4: Connect to the external USB cable of device.
Step 5: Recheck if you are connected to the correct Virtual COM port. Find the correct Virtual COM port (COM3) or other port (COM7 or COM10) by searching for "Device Manager" in windows.
Step 6: Keep the device on the main screen, then double-click the power button on the right until you see a USB key icon, which means data is being uploaded through a USB cable.
Step 7: Create a new folder to place the data table.
Important: The number of records stored in the CO2 sensor is limited to 90 records. After reaching the 90-record limit, the first record will be deleted and replaced by the latest record. The frequency of records in one day will determine the number of days before the device starts to delete the first record.
Following table provides a clear overview of the inter-record unit, its corresponding frequency, and the number of days before the device starts to delete the first record.
