4 Test Functions:

1.Battery Test:
The battery test is used to check and analyze whether the battery is in good condition.

2.Charging Test:
The charging test is used to check and analyze the status of the charging system (generator, rectifier, rectifier diode, etc.).

3.Cranking Test:
The cranking test is used to test and analyze the actual cranking current and voltage required to verify whether the starting motor is working properly or not.

4.Load Test:
The Load Test is used to check and analyze whether the battery has enough load capacity to run all electrical equipment such as playing car music, etc.

1.Battery Test

pre-test Preparation：
if the car is being started,turn off the engine and turn the car lock key to the “OFF”Position

Operational Steps >Accurate Test:

1.The test clamp connects the positive and negative pole of the battery

2.Press the〈▲〉<▼> key to select the in-car test item and then press the key to enter the selection

3.Press the〈▲〉<▼> key to select the battery test item and then press the key to enter the selection

4.Select the tested battery type. Press <▲> <▼> key to select the corresponding type and then press key to enter the selection

5.According to the standard of the battery, press〈▲〉 <▼> key to choose the test standard, if the battery is "JIS" standard, you can directly input CCA (when CCA parameters are known)

6.According to the standard value marked on the battery under test, press〈▲〉<▼> key to adjust the battery testing reference standard value (taking a standard 500CCA battery as an example )r long press〈▲〉<▼> key to achieve continuous adjustment of the value

7.After adjusting the standard value, press the < 0K> k^to carry out the test, and press the <▲> <▼> keys to check the battery life (SOH) and battery capacity (SOC) respectively

Charging System Test:

pre-test Preparation:
If the car is in the flame out state, please start the car engine first

Operation steps:

1.When the car is in the starting state, the test damp is connected to the positive and negative poles of the battery under test (there is no difference between the positive and negative poles of the test damp of this equipment, which can be connected at will). Attention must be paid to check whether there is good contact.

2.Press <▲> <▼> key to select the charging test Item, and then press to enter the the test

3.Enter the ripple test interface,the smaller the waveform float,the more stable the voltage.

4.After waiting for 10 seconds on the ripple test Interface, the Instrument will prompt the following interface> Charging test

5.5)After operating as prompted in step 4, press the toy to obtain the charging test result. As shown:

2.Start Test Of Starter System:

Preparation before test：
If the car is starting, please turn off the engine and turn the car lock key to the "OFF position.

Operation steps:

1.1.The test clamp connects the positive and negative pole of the battery

2.Press the <▲> <▼> to select the start test item and then press the key to enter the test

3.Afer entering the startup test, the instrument will prompt the following interface> Start Load Test

4.After completing the operation according to the prompt, you can get the start load test result

Load System Test:

Preparation before test:
if the car is turned off,please start the car engine first

Operation steps:

1.When the car is in tho starting state, the test damp is connected to the positive and negative p- oles of the testing battery (There is no difference between positive and negative electrodds in the test clamp of this equipment, which can be connected at will).

2.2)Press the〈▲〉<▼> key to select the load test item and then press the to test.

3.After entering the load test, the instrument will prompt the following interface:>Load Test

4.4)After operating as prompted In step 3, press to get the load test result, as shown In the figure:

5.Read the lowest voltage value. If the voltage reading Is greater than 12.80 V (fora 24 V system, the voltage reading Is greater than 25.60 V), it means that the load system Is normal

Description of load system:

★ If the voltage reading is less than 12.80 V (for a 24 V system, the reading is less than 25.60 V), p- lease check whether the generator belt is worn out and the wires are short-circuited.

Real-time Voltage Test in Waveform：

It supports the Ripple Test of the Charging System. Just one click read the real-time voltage change in the graph. The waveform displays current voltage, maximum, and minimum voltage during ignition. And it can keep 10 waveform monitoring records, Playback the saved waveform data, and one-click clear all saved waveform data; Its Record management can only record the results of the last battery test.

Ensure The Safety During Testing:

It can intelligently identify the positive and negative poles of the battery. Regardless of whether the positive and negative poles are reversed, the tester can work normally and will not lead to burnout of the product. More convenient to use, and can well protect the equipment and battery.

Screenshot:

It has a one-click screen capture function with long press "Up" and " Down" button., which is used to capture and save important data, fast and convenient.
