4. Data Logging to SD Card
The SDL600 can log data directly to the inserted SD card in Excel format. This allows for easy transfer to a PC for analysis.
- Set Sampling Rate: The sampling rate is user-programmable from 1 to 3600 seconds. Access the menu settings (refer to device interface) to configure your desired interval.
- Start Logging: Press the dedicated LOG button to begin recording data. The device will record readings with a date and time stamp.
- Stop Logging: Press the LOG button again to stop recording.
- Transfer Data: Remove the SD card and insert it into a computer to access the logged data files.
5. Internal Memory Storage
The device's internal memory can store up to 99 readings manually. Consult the device's interface for instructions on how to save and recall these readings.
6. Auto Power Off
The SDL600 features an Auto Power Off function to conserve battery life. This feature can be disabled through the device's settings menu if continuous operation is required.
Maintenance
1. Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the microphone and display are kept clean for accurate readings.
2. Storage
When not in use for extended periods, remove the batteries to prevent leakage. Store the device in its hard carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
