1. Convenient and practical, power-off, no need to tie, leakage detection
2. Pure copper battery holder, spring clip
3. Connect the black stylus to the other end of the battery holder
4. Attach the red stylus to the other end of the spring clip
5. Material: metal + plastic
6. Net weight: 33g

Use caution:
1. Please turn off the engine and pull out the key before testing, do not start the engine in order to avoid burning the fuse
2. Leakage detection needs to simulate the normal car does not start the state, please be sure to close the door to pull out the key (can be locked) , another car computer into hibernation
3. Different models of computers into the state of sleep time is not the same, please wait patiently when measuring, in order to determine whether there is leakage current generated
4. Different models of computer standby current varies, the ideal value of 20 ma 60 Ma
5. To replace the fuse of the measuring instrument, use the fuse of 10A to avoid burning the multimeter
