3. Podešavanje

3.1 Napajanje uređaja

Connect the EL15 to a 5V 2A power source using the provided USB Type-C cable. The USB TYPE-C Power Input Port (5) is located on the rear of the device.

3.2 Povezivanje tereta

The EL15 supports both local and remote measurement configurations.

3.2.1 Local Measurement

Suitable for quick measurement scenarios. Connect the positive (red) and negative (blue) load wires from the source under test directly to the 4mm Load Input Ports (1 and 3) on the EL15.

3.2.2 Remote Measurement

Suitable for high-precision measurement scenarios. In addition to the two load wires (positive and negative) for current transmission, two remote compensation wires (connected to the XT30 male connector) are used for detecting the actual output voltage of the source under test. Connect the XT30 male connector to the Remote Compensation Input Port (2).

4. Načini rada

The EL15 offers a variety of measurement modes accessible via the multi-function keyboard (6) and the 1.9-inch IPS LCD Screen (4).

4.1 Osnovni načini mjerenja

These modes allow the EL15 to operate as a constant current, voltage, resistance, or power load.

• Režim konstantne struje (CC): The load will draw a constant current at the set value, regardless of input voltage promjene.
• Constant Voltage-Mod (CV): The load maintains the input voltage at a constant value by drawing current.
• Režim konstantnog otpora (CR): The load acts as a constant resistor, dynamically adjusting the load current according to the input voltage.
• Režim konstantne snage (CP): Dynamically adjusts the load current to make the load consume constant power.

4.2 Battery Measurement Mode

This mode is ideal for evaluating battery performance.

• Capacity Test (CAP): By recording discharge time and current under constant-current discharge, the actual capacity of a battery or energy storage device is calculated. Applicable for battery capacity evaluation, energy storage device testing, battery aging analysis, and product quality inspection.
• DC Internal Resistance Measurement (DCR): The DC internal resistance, derived from the voltage change between two pulsed load currents, is a key parameter for evaluating a power supply's power characteristics, output performance, and state of health.

4.3 Power Supply Measurement Mode

Designed for comprehensive power supply evaluation.

• Dynamic Test (DT): Simulates real-world load changes with alternating current levels to evaluate power supply response speed, efficiency, reliability, and safety.
• Automatic Test (AUTO): Streamlines testing with one-click automation. After configuring initial rated termination and step currents, the system provides a comprehensive suite of metrics, including rated power, voltage to maximum current, power, and load regulation.

4.4 Advanced Measurement Mode

For more complex and automated testing sequences.

• List Test (LIST): Stores up to 10 sets of current and duration parameters to perform complex testing under multiple conditions. Useful for dynamic performance testing, automated verification, and quality control.
• Scan Test (SCAN): By setting low current, high current, and rise/fall time, dynamic response performance testing of the device under test can be realized.

4.5 Screen Interfaces

The 1.9-inch IPS LCD screen provides intuitive navigation and data display.

• Glavno sučelje: Displays real-time measurements (voltage, current, power) and current operating mode.
• Podešavanje interfejsa: Allows configuration of device parameters such as screen off time, temperature units, language, and buzzer settings.
• Measurement Interface: Provides detailed real-time data for the selected measurement mode.
• Automatic Measurement Report Interface: Shows results and statistics after completing an automatic test.

• ventilacija: Ensure the radiator air inlets (8) and outlets (7) are clear of obstructions to allow for proper airflow and heat dissipation.
• Održavanje kablova: Inspect all cables (USB, alligator clips, XT30) regularly for any signs of wear or damage. Replace damaged cables immediately.

7. Otkrivanje problema

If you encounter issues with your EL15, refer to the following common troubleshooting steps:

• Uređaj se ne uključuje: Ensure the USB Type-C power cable is securely connected to a 5V 2A power source. Try a different USB cable or power adapter.
• No Load Detected: Check that the load wires are correctly and securely connected to the 4mm Load Input Ports. Verify the source under test is providing power.
• Netačna očitavanja: If using remote measurement, ensure the compensation wires are correctly connected and the remote measurement option is selected in the device settings. Check for loose connections.
• Problemi sa Bluetooth vezom: Make sure Bluetooth is enabled on your mobile device. Ensure the EL15 is within range. Restart both the EL15 and the "ATK-xTOOL" app.
• Upozorenje na previsoku temperaturu: Check that the cooling fans are operating and that the air inlets/outlets are not blocked. Reduce the load if the warning persists.

9. Savjeti za korisnike

Here are some tips to enhance your experience with the ALIENTEK EL15:

• Počnite jednostavno: If you're new to electronic loads, begin with Constant Current (CC) or Constant Voltage (CV) modes to familiarize yourself with the device's basic operation before moving to more advanced tests.
• Temperatura monitora: While the EL15 has efficient cooling, always ensure good ventilation, especially during prolonged high-power tests, to prevent overheating.
• Use Remote Sensing for Accuracy: For critical measurements, especially with longer test leads or higher currents, utilize the remote compensation input (XT30) to minimize voltage drop errors and achieve higher accuracy.
• Istražite aplikaciju: The "ATK-xTOOL" mobile app offers convenient remote control and data logging features. Take time to explore its functionalities for easier test management and analysis.
• Sigurnost na prvom mjestu: Always double-check your wiring connections before applying power to avoid reverse polarity or short circuits, despite the built-in protections.
