2. Connect to PC: Plug the TempU04 device into a USB port on your computer.
3. Configure Parameters: Use the downloaded software to set parameters such as:
   • Logging interval (e.g., 10 minutes, default)
   • Start delay (e.g., 30 minutes, default)
   • Alarm delay (e.g., 10 minutes, default)
   • Alarm range (e.g., <2℃ or >8℃, default)
   • Temperature unit (℃ or ℉)
   • Preset time start
4. Save Settings: After configuring, save the settings to the device through the software. Note that all previously recorded data will be cleared when parameters are set or the unit is restarted.

3. Operating Instructions

3.1 Device Overview

Figure 3: TempU04 LCD Display and Button Functions. This image highlights the LCD screen showing temperature value, unit, high temp alarm, battery life, and the functions of the 'OK' (Start/Scroll/Mark) and 'ALARM' (Stop) buttons, along with the USB port and status indicator light.

3.2 Starting and Stopping Logging

1. Start Logging: Press and hold the 'OK' button (Start/Scroll/Mark) for a few seconds until the status indicator light confirms logging has begun. If a start delay is configured, logging will commence after the specified delay.
2. Stop Logging: Press and hold the 'ALARM' button (Stop) for a few seconds to stop the recording process. The device will indicate that logging has ceased.

3.3 Reading the LCD Display

The LCD screen provides real-time information:

• Temperature Value: Displays the current temperature.
• Temperature Unit: Indicates whether the temperature is in Celsius (℃) or Fahrenheit (℉).
• High Temp Alarm: An icon will appear if the temperature exceeds the set upper alarm limit.
• Battery Life: Shows the remaining battery charge.
• Current Recording Points: Indicates the number of data points recorded.

3.4 Data Retrieval and Report Generation

Once logging is complete, retrieve your data:

1. Connect to PC: Plug the TempU04 into a USB port on your computer.
2. Automatic Report Generation: The device will automatically generate a PDF and CSV data report. No special software is required for this step. The reports will typically appear as a removable drive on your computer.
3. Access Reports: Open the generated PDF or CSV files to view the recorded temperature data, graphs, and summary statistics.

4. Maintenance

4.1 Battery Replacement

The TempU04 uses a replaceable CR2032 3.0V battery. When the battery life indicator on the LCD shows low power, replace the battery to ensure continuous operation and data integrity. Refer to the device's back panel for instructions on opening the battery compartment.

4.2 Cleaning

To clean the device, simply wipe it with a clean, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the casing or screen.

4.3 Data Management

Remember that changing parameters via the software or restarting the device will clear all previously recorded data. Always retrieve and save your data reports before making any configuration changes.

5. Troubleshooting

• Device Not Recognized by PC:
  Ensure the device is firmly plugged into a functional USB port. Try a different USB port or computer.
• No Data Report Generated:
  Verify that logging was successfully started and completed. Ensure the device is connected correctly to the PC. If parameters were changed, remember that previous data might have been cleared.
• Blank LCD Screen:
  Check the battery level. If low, replace the CR2032 battery.
• Incorrect Temperature Readings:
  Ensure the device is placed in an appropriate environment for measurement. Verify the temperature unit (℃/℉) and calibration settings via the configuration software if available.
• Logging Not Starting:
  Confirm that the 'OK' button was pressed and held long enough to initiate logging. Check if a start delay is configured in the software.
