Press the up and down keys to switch between SOH and SOC

Battery test result includes 5 types as following: ( Good Battery / Good, Recharge / Replace / Bad cell, Replace / Charge, Retest )

• Waveform: press WAVEFORM FUNCTION button, The screen will display the interface as shown below:

CUR: Current Voltage
MAX: Maximum Voltage during Ignition MIN: Minimum Voltage during Ignition
The waveform will stay in static until there are changes in the voltage changes detected
Various vehicle voltage analyses

• Discharge Voltage: When the ignition is OFF, the engine is OFF (Over 20 Minutes), the Discharge Voltage should be around 12V. If the discharge voltage is lower than 11V, it will be hard to turn the ignition If the discharge voltage continuously stays under 11V, it means the battery is aging and replacement is needed.
• Starting Voltage: During ignition, the voltage will drop to a certain point, at this minimum point is Starting Voltage (Around 7.5- 9.5V). If the Starting Voltage continuously stay under 7.5, it means battery capacity is low and needs to be replaced
• Charging Voltage: When the ignition is ON, the engine is ON. The alternator will continuously charge the car battery, normally is around 14V

Battery Status corresponding with Battery Voltage (Before Ignition)

Battery Status corresponding with Battery Voltage (After Ignition

electrical load
13.2-14.BV| Normal| Normal

14.BV| High Voltage| May damage the battery, Check alternator stabilizer

Notice: If the current detected battery voltage is 11.9V, after a few hours trip, the battery voltage still stays low, the cause could be battery damage (Under the circumstance of the normal alternator). Please replace the battery ASAP
