Review on Protmex AC Voltage Tester Pen - Non Contact Voltage Detector with Adjustable Sensitivity, Electrical Circuit Testers, Flashlight and Buzzer Alarm - Multi Range AC 12-1000V, Live/Null Wire Judgment by Justin Anderson
The tester wasn't exactly
The tester gave incorrect readings. Sometimes this interfered with the power supply, which wasn't the case. Basically the problem was that there would be indications of no power causing damage to other equipment. Wouldn't recommend it.
- Non-Contact Voltage Tester - it flashes and beeps when the device approaches an AC voltage that exceeds the specified voltage range without touching the object being measured, and with an audible alarm and LED to indicate adequate security measurement application
- Some errors
