The Value+ Automotive Battery Tester (the Tester) is designed for a
stationary battery system. It can automatically identify 12V and 24V
battery.
The Tester is designed to help user understanding the overall state of the
battery health, state of charge and discharge.
The Tester can quickly, easily and acccurately :
- provide battery health information;
- provide the state of charge information;
- check battery level;
- check battery internal resistance; and
- the discharge capability.
The Tester have:
- overload protection;
- bad contact indication;
- revese polarity protection; and etc.
Features of the tester include:
- battery internal resistance measurement;
- battery voltage measurement;
- discharge volts test;
- ripple voltage test;
- auto hold; and
- auto save.
The Tester is powered by the battery being test. It is no need to provide
any additional power to the tester. It is no need to take the battery being
test from the car. The Tester was designed to test the battery installed in
cars.
With careful use, the Tester will provide years of reliable service

To prevent possible electrical shock, fire, personal injury and ensure safety
operation and service of the Tester, please follow these guidelines:
• Read the instruction before use and follow all safety instructions.
• Use the Tester only as specified in the instruction card; otherwise, the Tester's safety
features may not protect you.
• Do not use the Tester and/or the accessory if they look damaged and / or wet.
• Do not use the Tester if it operates incorrectly.
• Do not use the Tester just before, during or just after an electrical storm (electrical
shock / high energy overvoltage!). Please make sure that your hands, your shoes,
your clothing, the floor, switches and switching components are dry.
• Never use the Tester if it just brought from a place with great temperature difference.

• Avoid to use the equipment in the environment with strong magnetic fields, strong
electrostatic fields and strong RF fields.
• Avoid simultaneous contact with battery and frame racks or hardware that may be
grounded.

• Use only probes, clips, and adapters supplied with the Product.
common clip.
• Disable the Tester if it is damaged.
• Only use probes, test clips, and accessories that have the same measurement
category, voltage, and amperage ratings as the Tester.
• Do not apply more than the rated voltage, between the terminals or between each

terminal and earth ground.
• Use the correct terminals, function, and range for measurements.
• Do not touch the probes to a voltage source when the clips are connected to the
current terminals.
• Personal injury or damage to the equipment can occur if you attempt to make a
measurement with a clip in an incorrect terminal.
• A " " statement identifies hazardous conditions and actions that could
cause bodily harm or death.
• A “ ” statement identifies conditions and actions that could damage the
equipment or the object under test.
