6. Operating Instructions

The KW218 offers several testing modes to diagnose your battery and charging system.

6.1. Battery Test

This function tests the overall health of the battery, including its State of Health (SOH), State of Charge (SOC), internal resistance, and voltage.

1. From the main menu, select 'Battery Test' using the arrow buttons and press 'ENTER'.
2. Follow the on-screen prompts to input battery type (e.g., Flooded, AGM) and CCA rating.
3. The tester will display results such as SOH, SOC, CCA value, voltage, and a general status (e.g., 'GOOD BATTERY', 'REPLACE').

6.2. Cranking Test

The Cranking Test evaluates the vehicle's starting system, including the starter motor. It measures the cranking voltage and time.

1. From the main menu, select 'Cranking Test' and press 'ENTER'.
2. Follow the on-screen instructions to start the vehicle.
3. The tester will record the minimum cranking voltage and the cranking time, providing a 'CRANKING NORMAL' or 'CRANKING ABNORMAL' status.

6.3. Charging Test

This test assesses the vehicle's charging system, including the alternator and regulator, by measuring the loaded and unloaded voltage, and ripple voltage.

1. From the main menu, select 'Charging Test' and press 'ENTER'.
2. Follow the on-screen instructions, which typically involve starting the engine and revving it to a specified RPM.
3. The tester will display results such as loaded voltage, unloaded voltage, ripple voltage, and a 'CHARGING NORMAL' or 'CHARGING ABNORMAL' status.
