Main highlights

Voltage measurement range: 0.00V ~ 200V, Current measurement range: 0.00A ~ 20A.

Two power supply methods: 1. DC6-12V DC5.0 power supply; 2. DC6-12V Micro USB power supply.The body discharge power cannot exceed 150W, otherwise there is a risk of burnout.

Prevent burning warning: when the input voltage battery and large power test, access must be beforeusing two current adjustment knob counterclockwise to the minimum to zero, then the access, accordingto the priority according to current power to slowly adjust current knob, must not instantly transferred infull, so there are excessive instantaneous power load discharge tube burnt huge risk! Please use thespecial attention to this point, thank you!
