High-grade display testing meter
AC/DC voltage test range:12,36,55,110 to 220V
Size:φ3x136mm
Use description
This neon-electroscopeis applicablefordirectly detection ofl2-220Vzeroline,indirect detection of DC,AC power inner conductor,phase conductor and break-point detection.
1、Press Direct Measu ring ElectrodeAto directly measure AC voltage
2、Press induction Measu ring 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 the hand-g ripping
end is positivepole,the contact end is negative pole.If the indicating lamps on both ends are brihgt,it
means short-cireuit.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 rend by hand ifthe 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 detectthe break—point.Move along the phase conductor excluding the head if the indicaging lamp is dark,it the break-point
8、It is strictly forbidden to press both electrodes at the same time in use
