This tester is suitable for measuring 12-220v AC & DC directly as well as measure the ground, phase & breakpoint of the AC directly. Batteries included -  Bulk packed - no retail packaging.

Voltage measurement

• The final digits are the measured voltage

• If the display value cannot reach 70% of the high section, it will display the lower section

• use induction pole when measured bodies is under 12 volts (charged or not)

• When induction body is under measured, it must connect to ground.

Induction measurement

• When measurement is performed on one of the parallel lines, it is necessary to widen them, or eliminate interference
