* When the engine is running, avoid contact with high temperature parts such as water tanks and exhaust pipes.
* When the battery holder is energized, do not use it to hold the body

Precautions for instrument use

1.The instrument for precision electronic equipment, do not fall.
2.The first time open device, the instrument may respond slowly, please be patient, do not frequently operate the instrument.
3.The display may flash once when ignition, is a normal phenomenon.
4.If the display flashes, the program is interrupted, please turn off the power, re-boot device.

6.When the welding operation on the car, the power should be cut off in advance of the ECU system.
7.Do not use test lights to test electrical equipment related to the ECU to prevent damage to the ECU or sensor unless specified.
9.Except the special instructions in the test procedure, the ECU and the sensor can not be tested 8.with a pointer-type ohmmeter, but should be tested using a high-resistance digital meter.
