5. Setup
5.1 Charging the Device
- Connect the provided Type-C charging cable to the device's charging port.
- Connect the other end of the cable to a 5V/1A USB power adapter (not included).
- The battery indicator on the display will show charging status. Ensure the device is fully charged before first use for optimal performance.
5.2 Power On/Off
- Power On: Short press the bottom button (usually labeled 'RUNIO' or similar) to turn on the device. The main measurement interface will appear.
- Power Off: Long press the bottom button to power off the device.
5.3 Connecting Test Leads
- Connect the four-wire Kelvin clips to the designated port on the side of the tester.
- Ensure a firm connection.
6. Operating Instructions
6.1 Basic Measurement
- Power on the device. The main interface will display voltage (V-Range) and resistance (R-Range).
- Carefully connect the four-wire Kelvin clips to the battery terminals. Ensure good contact for accurate readings.
- The device will automatically display the voltage and internal resistance values.
6.2 Navigating Menus and Settings
- From the main interface, long press the 'MENU' button to access the main menu, which includes Sorting, SET (Settings), and CAL (Calibration).
- Use the arrow keys (Up, Down, Left, Right) to navigate between menu options and adjust values.
- Press the 'AUTO' button (or the central button) to confirm selections or save changes.
6.3 Settings Menu (SET)
In the SET menu, you can configure various device parameters:
- Language: Switch between English (EN) and Chinese (CN).
- Shut Down: Set the automatic shutdown timer (e.g., 15 or 30 minutes, or NO for no auto-shutdown).
- Reset: Restore factory default settings.
- R_Color: Change the display color for resistance readings.
- V_Color: Change the display color for voltage readings.
6.4 Sorting Mode (Sorting)
The sorting mode allows you to quickly classify batteries based on predefined voltage and resistance thresholds:
- Navigate to the 'Sorting' menu.
- Use the arrow keys to set the upper and lower limits for both voltage and resistance.
- Once limits are set, the device will indicate 'Pass' or 'Fail' for each tested battery, along with a count of passed and failed items.
6.5 Calibration Mode (CAL)
The calibration mode allows for multi-point calibration of voltage and resistance to maintain measurement accuracy. Calibration values can be saved, and factory settings can be restored if errors occur.
- Navigate to the 'CAL' menu.
- Select 'Resistance Calibration' (R-CAL) or 'Voltage Calibration' (V-CAL).
- Follow the on-screen prompts to perform the calibration. Use known reference values for best accuracy.
- Select 'Ok' to save the calibration or 'Cancel' to discard changes.

7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: For prolonged storage, charge the battery to approximately 50-70% every few months to maintain battery health.
- Test Leads: Inspect the Kelvin clips and cables regularly for any signs of wear or damage. Replace if necessary to ensure accurate and safe operation.
8. Troubleshooting
- Device not powering on: Ensure the battery is charged. Connect the Type-C cable and try again.
- Inaccurate readings: Check that the Kelvin clips are making good, clean contact with the battery terminals. Ensure the battery is within the device's specified voltage and resistance ranges. Consider performing a calibration if readings are consistently off.
- Display issues: If the screen is frozen or unresponsive, try powering off and on the device. If the issue persists, perform a factory reset via the SET menu.
- Device unresponsive: If the device becomes unresponsive, try a long press of the power button to force a shutdown, then restart.
