Usage Instructions

Use the Data Logger for the First Time

Before using the data logger for the first time, install the provided drive software. Insert the data logger into a USB port and follow the on-screen prompts to install the drive software. Once the software is open and the data logger is connected, it will automatically upload information. View this information and save the configuration to calibrate the time.

Stop the Data Logger

The data logger can be stopped using several modes: manual stop, stop when maximum record capacity is reached (with or without manual stop enabled), or stop via software.

Manual Stop: Press and hold the button for 5 seconds to stop recording. Alternatively, use the software to stop the logger. If the logger reaches its maximum capacity (32,000 points) and is not manually stopped, it will continue recording by overwriting the oldest data, while retaining statistical information for the entire process. Note: If the record capacity exceeds 32,000 points in manual stop mode, the logger continues recording temperature but only stores the last 32,000 points. Use this mode cautiously if detailed historical data is critical.
Stop when Max Capacity Reached (Manual Stop Enabled): The logger stops manually via button or software, or automatically when the record capacity reaches 32,000 points.
Stop when Max Capacity Reached (Manual Stop Disabled): The logger stops automatically when the record capacity reaches 32,000 points, or it can be stopped via software.
Stop via Software: The data logger can be stopped at any time using the software, regardless of the current mode.

Start the Data Logger

There are three modes to start the data logger:

Instant-on: After parameter configuration, the data logger begins recording immediately upon disconnection from USB.
Manual Start: After parameter configuration, press and hold the button for 5 seconds to start recording. This mode includes a start delay function; if enabled, recording begins only after the specified delay time has elapsed.
Timing Start: After parameter configuration and disconnection from USB, the data logger starts recording automatically when the set time is reached.

Configure Parameters

Refer to the data management software instructions for detailed parameter configuration. When connected via USB, the data logger displays Figure 19, indicating USB connection.

View Data Temporarily

For quick statistical information, press the button to cycle through pages on the LCD screen. The screen can display the MKT (Mean Kinetic Temperature), average, maximum, and minimum values. For detailed information, connect the data logger to a computer via USB. Within a few minutes (typically 3), the data will be saved to the USB disk as a PDF report. The data logger can also be connected to a computer to analyze data vertically and horizontally using the data management software.

View Data

Connect the data logger to a computer via USB to view the recorded data. The exported PDF report can be found on the USB disk. Alternatively, import the data into the data management software to view configuration information and recorded data.

Display Menu Instruction

The data logger's LCD displays various information pages based on settings. The following describes the information typically shown:

Menu 1: Start Delay Time or Remaining Time

Displays the start delay time or the remaining time until recording begins (Hr:Min. 10Sec). The digit after the decimal point represents increments of 10 seconds. For example, Fig. 2 shows 10 minutes and 20 seconds remaining for the logger to start. This page is visible only when start delay or timing start is active.

Fig. 1: Logger in timing start mode, displaying '39:18.2'.

Fig. 2: Logger in start delay mode (flashing), displaying '00:10.2'.

Menu 2: Current Temperature

Shows the current temperature. A static display indicates recording is in progress. Fig. 3 shows a current temperature of 23°C with no alarm. Fig. 4 shows a current temperature of 30.4°C with an alarm condition.

Fig. 3: Current temperature (No alarm occurred).

Fig. 4: Current temperature (Alarmed).

Menu 3: Current Record Points

Displays the number of current record points. If the number exceeds the maximum capacity (32,000 points), the display remains static, indicating that the logger is recording circularly (overwriting old data). Fig. 5 shows 32,000 record points.

Fig. 5: Current record points (Static indicates the current record points exceed the Max capacity and the data logger recorded circularly).

Menu 4: Current Record Interval

Shows the set record interval. The digit N following the decimal point represents N*10 seconds. Fig. 6 indicates the record interval is set to 12 minutes and 50 seconds.

Fig. 6: Record interval, showing '00:12.5' (12 minutes 50 seconds).

Menu 5: MKT Value

Displays the Mean Kinetic Temperature (MKT). A static indicator signifies that the logger has stopped recording. Fig. 7 shows an MKT value of 18.3°C.

Fig. 7: MKT value, showing '18.3'.

Menu 6: Average Temperature Value

Shows the average temperature recorded. Fig. 8 displays an average temperature value of 4.5°C.

Fig. 8: Average temperature value, showing '4.5'.

Menu 7: Max Temperature Value

Displays the maximum temperature recorded. Fig. 9 shows a maximum temperature value of 9.8°C.

Fig. 9: Max temperature value, showing '9.8'.

Menu 8: Min Temperature Value

Displays the minimum temperature recorded. Fig. 10 shows a minimum temperature value of 2.7°C.

Fig. 10: Min temperature value, showing '2.7'.

Menu 9,10,11: Set Upper Limit of Temperature

These menus allow setting up to three upper temperature alarm limits. Fig. 11 shows Upper Limit 3 set to 25.0°C. Fig. 12 shows Upper Limit 2 set to 15.0°C. Fig. 13 shows Upper Limit 1 set to 10.0°C.

Fig. 11: Upper limit 3 set to 25.0.

Fig. 12: Upper limit 2 set to 15.0.

Fig. 13: Upper limit 1 set to 10.0.

Menu 12,13: Set Lower Limit of Temperature

These menus allow setting up to two lower temperature alarm limits. Fig. 14 shows Lower Limit 1 set to 0.0°C. Fig. 15 shows Lower Limit 2 set to -5.0°C.

Fig. 14: Lower limit 1 set to 0.0.

Fig. 15: Lower limit 2 set to -5.0.

Other Status

The logger can display various status indicators:

Fig. 16: Indicates data deletion process, showing 'PDF 38%'.
Fig. 17: Indicates data recovery (Power on) status.
Fig. 18: Indicates report generation progress.
Fig. 19: Indicates USB connection status.

Content of PDF Report

The content of the PDF report varies based on the configured alarm types. If the logger is set to "no alarm", the report will not display alarm information in the top right corner or use color markings for data. When alarms are enabled, relative alarm information is presented in an alarm info column, corresponding to the selected alarm types. Data exceeding the high temperature limit is shown in red, data below the low temperature limit is shown in blue, and normal data is in black. The top right corner of the first page will indicate "alarm status" if alarms occurred; otherwise, it will show "normal status".

Finish View

After reviewing the report, exit the data logger application or disconnect the device.
