2. Battery Installation

The TempU 03 uses one 3V 210mAh CR2032 button battery. Ensure the battery is correctly installed before first use or after replacement.

1. Carefully remove the removable case from the bottom of the device to expose the battery compartment.
2. Insert the CR2032 battery with the positive (+) side facing upwards.
3. Replace the removable case, ensuring it clicks securely into place.

3. Initial Configuration (Optional)

While the device can generate reports without software, advanced parameters such as logging interval, start delay, alarm thresholds, and time zone can be configured using a dedicated software. Connect the device to a computer via its USB interface to access these settings.

Operating Instructions

1. Starting Data Logging

The TempU 03 can be started in two ways: by button press or via software configuration.

• Button Start: Press and hold the Start/Scroll/Mark Button (Triangle) for approximately 3 seconds until the "REC" icon appears on the LCD, indicating that recording has begun.
• Software Start: If configured via software, the device may start logging automatically after a set delay (default: 30 minutes) or upon a specific event.

2. Monitoring Data

The LCD display shows real-time temperature and humidity readings. Press the Start/Scroll/Mark Button (Triangle) briefly to cycle through different display modes, such as current readings, maximum/minimum values, and alarm status.

3. Stopping Data Logging

To stop recording, press and hold the Stop Button (Square) for approximately 3 seconds until the "END" icon appears on the LCD. Once stopped, the device will finalize the data and prepare it for report generation.

4. Generating Reports

After logging is complete, connect the TempU 03 to a computer's USB port. The device will automatically generate a PDF report and a CSV data file in its root directory. These files can be accessed and saved like any standard USB drive.
