Electrical safety rules

Do not twist or severely bend the power cord, as this may damage the internal wiring. If the power cord shows signs of damage, do not use the electrical system tester.

Damaged cables pose a risk of electric shock. Keep the power cord away from heat sources, oil, sharp edges, and moving parts. Damaged power cords must be replaced by the manufacturer, its technicians, or personnel with similar qualifications to prevent hazardous situations or injuries.

Equipment safety rules

Never leave the equipment unattended when it is powered on. Always disconnect the power cable and ensure the device is turned off when it is not being used for its intended purpose!
When pressing the tool’s power switch, the battery current and voltage may be directly conducted to the ground or certain circuits, potentially causing sparks. Therefore, do not use the tool near flammable materials, such as gasoline or its vapors.
Do not attempt to repair the equipment yourself.
Before connecting the device to power, check that the battery voltage matches the value specified on the nameplate. Mismatched voltage can cause serious hazards and damage the device.

Personnel protection safety rules

Protective gear may be worn when using this product.
Place chocks under the wheels and do not test the vehicle while it is unattended.
Exercise caution around the distributor cap, ignition wires, and spark plugs when working near the ignition coil. These components generate high voltage when the engine is running and can be dangerous.
Shift the transmission into ‘Park’ (automatic transmission) or ‘Neutral’ (manual transmission), and make sure to engage the handbrake.
Do not connect or disconnect any test equipment while the ignition switch is on or the engine is running.

Always ensure you have a stable footing to safely control equipment in case of emergencies.

Any other use is considered beyond the intended purpose of the equipment and is prohibited.

CAUTIONS
Safety precautions
Before using the instrument, please read this manual carefully for proper operation.

The tester is suitable for both 12V and 24V vehicle batteries.
The tester is suitable for operation at voltages ranging from 9V to 35V direct current (DC).
If the battery is just fully charged, the voltage will be slightly higher than normal. Therefore, please turn on the headlights for 2-3 minutes and wait until the voltage drops back to normal. Then turn off the vehicle appliances and proceed the test.

Before use, check that the test fixtu re insulation is intact, orthatthere are exposed and broken wires. Do not use until the back cover is closed, otherwise there is a risk of electric shock.
Do not use and store the instrument in high temperatures, high humidity, flammable, explosive and strong electromagnetic fields.
Do not change the internal wiring of the instrument to avoid damage to the instrument and other safety hazards.

Wear qualified eyewear when testing or repairing the car to prevent unknown objects from flying into your eyes when the engine is started.
Please run and maintain the car in a well-ventilated environ-ment to prevent inhalation of toxic gases.
If the car’s engine is running, do not place the instruments and accessories next to the engine or exhaust pipe as they may be damaged by high temperature.

OPERATIONS INSTRUCTION

Function instructions

The tester is powered only by the vehicle battery. Clamp the red and black clips of the tester to the positive (+) and negative (-) terminals of the battery safely and securely respectively. It is recommended to clip the red clamp first, then the black clamp, until the screen shows the following picture, the tester is in operation.
If the tester indicates poor connection, recheck that if the clamp connection is completely secure. Then proceed to the test program to select the appropriate language and adjust the system time.

Battery capacity
The tester will test the cranking capacity of the batteries and will determine the condition of the batteries based on the rated cranking capacity marked on each battery.

Please make sure the engine and all electrical equipment on the vehicle is shut down before testing. If the battery is just fully charged, the voltage will be slightly higher than normal. There-fore, please turn on the headlights for 2-3 minutes and wait until the voltage drops back to normal. Then turn off the vehicle appliances and proceed the test.
Select “Main Menu” in the item, press <▲> <▼> key to select “BATTERY CAPACITY” item, then press <OK> key to enter.
According to your actual battery type, press the <▲> <▼> key to select the right “Battery Type”, and press the <OK> key to proceed to the next step.

According to the standard type of cranking current marked on the battery body, press the <▲> <▼> key to “Select Input” the right rated starting type, and press the <OK> key to proceed to the next step.
According to the rated cranking current value marked on the battery body, press the <▲> <▼> key to adjust the standard value of “CCA RATED”, and press the <OK> key to enter the test.
