The Megger TPT420 Voltage Detector is designed to give electricians and electrical engineers an easy-to-use voltage tester that works even when the battery is exhausted. The TPT420 is extremely versatile - it is equipped with both LCD and LED displays and offers both AC and DC voltage measurements from 12 to 1000 V AC and up to 1500 V DC. In addition, a pass-through function is included in the range of 0 to 500 k. An acoustic signal provides continuity and voltage measurements for added safety. An integrated, bright LED torch makes it easy for the operator to work in low light conditions. The TPT420 operates below the trigger threshold to ensure that the RCD/FI circuit breaker is not inadvertently triggered when testing between phase and ground. The cross-over of the test probes used up to now is used with the TPT No need to display the rotating field direction. It can also carry out a single-pole voltage display test. For your safety, the TPT420 complies with cat IV 1000 V standard a
