Digital display electric pencil multifunctional voltage test pen

The electric pen is suitable for directly measuring the zero line, phase line and breakpoint detection of 12-220V and indirect detection of alternating current.

1. Holding the direct measuring electrode A can directly measure AC voltage.

2. Holding the inductive measuring electrode B can directly measure the DC voltage.

3. The alternating current phase and zero line can be measured. If the contact is measured with a pen contact, if it is shown as a phase line.

4. a breakpoint can be measured, except for the head moving along the phase line, or at the break point if there is no indication
