CNBJ-611 Automobile Current Tester<operating manual>

Application Description:

This product can be used to measure the current at the fuse box of standard blade fusesand is suitable for fault detection of electrical circuits in automobiles or commercial vehicles.possess fast measurement, high precision, easy to use and so on.

Product Features:

1.) Front lighting: convenient for detection and maintenance in the dark,Can also be used as alighting work lamp

2.) LCD screen: comes with blue backlight display for daytime,Viewing measurement data under bad light such as night;

3.) Appearance design: advanced visual design, simple, smart, dynamic,Colorful collocation, etc..

Note：

1. This tester can only be used for current measurement of vehicles.

2. The blade safety may become hot during the test. Please cool it before touching it.

3. Do not exceed the maximum load of the tester: maximum 20A 48V / 10 seconds.

4. Turn off the ignition switch of the vehicle before connecting or disconnecting the tester.

5.Do not disassemble the tester or modify its circuit.

6. Keep tester dry at all times.

7. Do not force the cable of the tester.

8, Do not use an abnormal or damaged tester.

9. Do not store the tester within reach of children or infants when you are not using it.

Operation method:

1. Tum off the ignition switch of the vehicle;

2. Remove the blade fuse attached to the tester from the jack, and then remove the vehicle’s fuse from the circuit to be tested and insert the tester’s safety in the wire socket, this ensures the correct level of circuit protection.(Fuses with the tester biade rating :20A/48V, standard type)

3. The plug of the tester (select medium or small according to the size of the blade fuse，if small, the small tail can be connected to the medium plug plug into the vehicle fuse socket.

4. Turn on the ignition switch of the vehicle if necessary to energize the circuit. Then turn on the tester (press the power button) and measure the current data.

5. The display will display the measured current data of the measured circuit.

6. When the display displays “DC”, that is, the circuit under test is a positive curentWhen “DC” is displayed, the circuit under test is a negative current;

7. After the measurement, turn off the tester (press the power button again).

Battery Replacement:

lf the symbol ” Battery logo ” is displayed on the display, the battery is insufficient andshould be replaced in time.Before removing the battery cover, tumm off the testerand ensure that the tester is disconnected from any circuits.
