Voltage Tester pen Fujian supplier good quality and lower price

Tester / test pencil / electroprobe / High-grade display voltage tester

This neon-electroscope is High-Grade display testing meter, appliable for directly detection of 12-220V zero line, indirect detection of DC, AC power inner conductor, phase conductor and break-point detection.

AC/DC voltage test range: 12, 36, 55, 110 to 220V

Size: Diameter3x142mm

1. Press Direct Measuring electrode A to directly measure AC voltage.

2. Press induction Measuring Electrode B to directly measure DC voltage.

3. Detect the uncharged conductor to see if there is any short-circuit to the electric wire, fluorescent lamp, capacitance, transformer, two ends of the electric motor coil, it shows good condition if it bright to the indicating lamp of the neon-electroscope. The indicating lamp of the neon-electroscope is dark if there is any short-circuit.

4. Whiling detecting the positive and negative pole, if the indicating lamp is bright, then then hand-gripping end is positive pole, then contact end is negative pole. If the indicating lamps on both ends are bright, it means short-circuit. If the indicating lamp is dark, it means circuit-break. Measure the audion according to the same method.

5. It can detect the positive and negative poles of low voltage DC voltage. Detect the contact end, grip another end by hand, if the indicating lamp is bright, then the neon-electroscope end is positive pole.

6. It can detect AC power phase conductor and zero line. While making detection by the neon-electroscope contact, if the indicating lamp is bright, it is the phase conductor.

7. It can detect the break-point. Move along the phase conductore excluding the head if the indicating lamp is dark, it is the break-point.

8. It is strictly forbidden to press both electrodes at the same time in us
