6. Operating Instructions
6.1 Basic Operation
- After powering on the device and connecting the battery, the LCD will display the main menu or default test screen.
- Use the SET Knob to navigate through menu options and adjust parameter values. Press the knob to confirm a selection or enter a value.
- Press the ON Button on the front panel to start or stop the load/charge function during a test.
6.2 Discharge Modes
The EBC-A10H supports three primary modes for battery testing:
- DSC-CC (Constant Current Discharge): Discharges the battery at a constant current. Ideal for determining battery capacity under a steady load.
- DSC-CP (Constant Power Discharge): Discharges the battery at a constant power. Useful for simulating real-world loads that draw constant power.
- CHG-CV (Constant Voltage Charging): Charges the battery at a constant voltage. Used for measuring charging characteristics and capacity.
Select the desired mode from the menu, set the parameters (e.g., current, voltage, power, cut-off voltage), and press the ON button to start the test.
6.3 Automatic Charge-Discharge-Charge Mode
This mode automates the process of fully charging, discharging, and then recharging a battery to accurately determine its capacity. This is particularly useful for new batteries or for re-evaluating older ones.
- Navigate to the 'Auto Test' or 'Capacity Test' option in the menu.
- Set the required charging and discharging parameters (e.g., charge current, discharge current, cut-off voltages).
- Start the test. The device will automatically cycle through charging, discharging, and final charging, displaying the measured capacity.
6.4 PC Software Operation
The PC software provides a graphical interface for controlling the EBC-A10H and visualizing test data.
- Launch the installed software on your computer.
- Ensure the EBC-A10H is connected via USB and powered on. The software should detect the device.
- Use the software interface to select test modes, set parameters, start/stop tests, and monitor real-time data.
