TPT420 Voltage Tester – Megger


With both LCD and LED displays, the TPT420 provides both AC and DC voltage measurement – from 12 to 1000 V AC and up to 1500 V DC. In addition, a continuity function within the range 0 to 500 kΩ, is included and for added safety, continuity and voltage measurements are also accompanied by an audible sound.  The meter continues to warn the operator of dangerous test voltages even when the batteries are exhausted.

A bright, integrated LED light aids the operator when working in poorly lit environments. When testing between phase and earth on any circuit protected by an RCD, RCBO and Safety Breaker, the TPT420 works below the tripping threshold of these devices to help avoid unintentional disconnection.  The phase rotation indication test has been simplified, which now avoids the crossing of the test probes, adopted by some 2 pole testers. The TPT420 can also perform a single-pole voltage indication test.
