Use the Data Logger for the First Time
To use the data logger for the first time, you need to download and install the data management software.
Download Software: Visit http://www.e-elitech.com/xiazaizhongxin/
Installation: Install the software first. Connect the data logger to a computer's USB port and install the driver software as prompted. Open the software; the data logger will automatically upload information upon connection. You can view information and save configurations to calibrate the time.
Configure Parameters
Refer to the data management software instructions for detailed parameter configuration. When connected via USB, the data logger displays the connection status as shown in Figure 19.
Fig. 19: USB connection status indicator.
Start the Data Logger
There are three modes to start recording:
- Instant-on: After parameter configuration, the data logger starts recording immediately upon disconnection from USB.
- Manual start: After parameter configuration, press and hold the button for 5 seconds to start recording. This mode supports a start delay function; if enabled, recording begins only after the set delay time elapses.
- Timing start: After parameter configuration and disconnection from USB, the data logger begins recording at the pre-set time.
Figures 1 and 2 illustrate the display during timing start or start delay status.
Fig. 1: Display showing timing start status (e.g., "00 hours 10.2 minutes").
Fig. 2: Display showing start delay status (e.g., "39 hours 18.2 minutes", with a flashing indicator).
View Data Temporarily
For simple statistical information, you can press the button to cycle through display pages. The LCD screen shows MKT, average value, maximum value, and minimum value.
For detailed information, connect the data logger to a computer via USB. Within approximately 3 minutes, the data will be saved to the data logger's USB disk in AI format. This report can be opened with an AI or PDF reader.
Alternatively, connect to a computer and use the data management software to analyze the data vertically and horizontally.
Figures 7, 8, 9, and 10 show the MKT, average, max, and min temperature values respectively. A static display indicates recording is active, while a flashing indicator (as seen in Fig. 2 for start delay) might denote specific statuses.

Fig. 9: Maximum temperature value display.
Fig. 10: Minimum temperature value display.
Stop the Data Logger
The data logger can be stopped using several methods:
- Manual stop: Press and hold the button for 5 seconds while the logger is recording. It can also be stopped via software. If the record capacity reaches the maximum (32000 points) and the logger is not manually stopped, it will continue recording circularly, overwriting the oldest data but retaining the statistical information for the entire transportation process. Use this mode with caution if full historical detail is required.
- Over-Max-record-capacity stop (enable manual stop): The logger stops automatically when record capacity reaches the maximum (32000 points), or can be stopped manually or via software.
- Over-Max-record-capacity stop (disable manual stop): The logger stops automatically when record capacity reaches the maximum (32000 points). It can only be stopped via software if manual intervention is desired before reaching capacity.
- Stop via software: The data logger can be stopped using the data management software in any mode.
View Data
Connect the data logger to a computer via USB to view recorded data.
- View AI report: Open the USB disk drive created by the data logger to access the exported AI report file.
- View report via data management software: Open the software, import the data, and the software will display configuration information and recorded data.
Display Menu Instruction
The data logger displays various pages based on the configured settings. The following describes the maximum display information. If a setting is not configured, its corresponding page will not appear during page turning.
Menu 1: Start delay time or remaining timing start time (Format: Hr:Min. 10Sec). Displayed only in start delay or timing start status.
Fig. 1: Timing start display (e.g., "00 hours 10.2 minutes").
Fig. 2: Start delay display (e.g., "39 hours 18.2 minutes", with a flashing indicator).
Menu 2: Current temperature. Static display indicates recording is active. Alarmed status is indicated visually (e.g., different color or icon).
Fig. 3: Current temperature display (No alarm occurred, e.g., "2.3°C").
Fig. 4: Current temperature display (Alarm occurred, e.g., "30.4°C").
Menu 3: Current record points. A static display indicates the current record points exceed the maximum capacity, and the logger is recording circularly.
Fig. 5: Current record points display (e.g., "32000").
Menu 4: Current record interval. The digit N following the decimal point represents N*10 seconds. For example, "00:12.5" indicates a record interval of 12 minutes and 50 seconds.
Fig. 6: Record interval display (e.g., "00:12.5").
Menu 5: MKT value. Static display indicates the logger has stopped recording.
Fig. 7: MKT value display (e.g., "18.3°C").
Menu 6: Average temperature value.
Fig. 8: Average temperature value display (e.g., "4.5°C").

Content of AI Report
The AI document's content varies based on the configured alarm types.
- If "no alarm" is set, there will be no alarm information on the top right corner of the first page, nor color markings within the data.
- If "alarm" is set, relative alarm information appears in the alarm info column according to the selected alarms. Over-temperature data is displayed in red, over-low-temperature data in blue, and normal data in black. If alarm cases occur, the status is marked on the top right corner of the first page; otherwise, it is in normal status.
