7. Operating Instructions

7.1 Powering On/Off

• Press and hold the Power button to turn the device ON or OFF.
• The device features an auto-shutoff function to conserve battery power after a period of inactivity.

7.2 Performing a Battery Test

1. Connect to Battery: Attach the red alligator clip to the positive (+) terminal of the battery and the black alligator clip to the negative (-) terminal. The device's plug-and-play design means you do not need to worry about polarity.
2. Select Test Mode: Use the Mode button to cycle through available test modes (e.g., internal impedance, voltage). The large LCD display will show the current mode.
3. Read Measurements: The device will automatically detect and display the internal impedance and voltage readings on the screen. The 3.2-inch TN color display ensures clear visibility.
4. Interpret Results: Refer to your battery's specifications or general battery health guidelines to interpret the displayed impedance and voltage values. Higher impedance generally indicates a weaker battery.

7.3 Using the LED Flashlight

• In dim environments, activate the built-in LED flashlight by pressing the designated Light button (refer to device diagram for exact button).

8. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
