- The LCD display will show the current temperature and humidity readings.
- Press the button repeatedly to cycle through different display modes: current readings, maximum recorded values (MAX), and minimum recorded values (MIN).
- To switch between Celsius (°C) and Fahrenheit (°F), press the dedicated °C/°F button if available, or hold the mode button for a few seconds.
6.2 Data Logging
The device automatically records temperature and humidity data at predefined intervals. The maximum memory capacity is 32256 data points. The logging interval and other parameters can be configured using the PC software.
6.3 Data Transfer to PC
- Ensure the PC software is installed.
- Remove the clear protective cap from the USB connector of the GM1365.
- Plug the device directly into an available USB port on your computer.
- Launch the installed data logger software.
- Follow the software's instructions to download the logged data, view graphs, and export reports.
7. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
- Battery Replacement: Replace the 1/2 AA 3.6V lithium battery when the low battery indicator appears on the display.
- Avoid Impact: Protect the device from drops and strong impacts, which can damage internal components or sensors.
8. Troubleshooting
- Device does not turn on: Check if the battery is installed correctly and has sufficient charge. Replace the battery if necessary.
- Inaccurate readings: Ensure the device is placed in a stable environment, away from direct heat sources, cold drafts, or high humidity sources that could affect readings. Allow sufficient time for the sensors to stabilize.
- Cannot connect to PC/transfer data: Verify that the USB connection is secure and the data logger software is correctly installed. Try a different USB port.
- Display is blank or flickering: This may indicate a low battery. Replace the battery.
9. User Tips
- For consistent readings, avoid placing the device in direct airflow from air conditioners or heaters.
- When comparing readings with other devices, ensure both are in the same location for at least 15-30 minutes to allow for stabilization.
