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 Karga konektatzea

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. Funtzionamendu moduak

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 Oinarrizko neurketa moduak

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

• Constant Current Mode (CC): The load will draw a constant current at the set value, regardless of input voltage aldaketak.
• Konstante Voltage Mode (CV): The load maintains the input voltage at a constant value by drawing current.
• Constant Resistance Mode (CR): The load acts as a constant resistor, dynamically adjusting the load current according to the input voltage.
• Constant Power Mode (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.

• Interfaze nagusia: Displays real-time measurements (voltage, current, power) and current operating mode.
• Interfazea ezartzea: 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.
