Megger - TPT420, Two-pole voltage & continuity tester 12-1000 V AC / 1500 V DC, phase rotation, torch, IP64, CAT IV 1000 V, COD 1013-189
DESCRIPTION
The Megger TPT420 voltage tester is designed to provide electricians and electrical engineers with an easy-to-use voltage indicating instrument. The tester will continue to warn the operator of dangerous voltages even when the batteries are exhausted. With both LCD and LED displays, the TPT420 measures AC and DC voltage from 12 to 1000 V AC and up to 1500 V DC. A continuity function within the range 0 to 500 kΩ is included, and for added safety both continuity and voltage indications are accompanied by an acoustic sounder.
When testing between phase and earth on any circuit protected by an RCD, RCBO or safety breaker, the TPT420 is designed to work below the tripping threshold of these devices to help avoid unintentional disconnection. The phase rotation indication test has been simplified and no longer requires crossing the test probes; the TPT420 can also perform a single-pole voltage indication test. A bright integrated LED torch helps in poorly lit environments.
With safety in mind, the TPT420 is rated CAT IV 1000 V with an IP64 housing and conforms to the latest IEC/EN 61243-3 and DIN VDE 0682-401 standards. GS38 probe tip shrouds are provided as standard, along with a protective storage and carry pouch.
APPLICATIONS
Although designed for testing within electrical installations, the unit can be used in almost any application where voltage and continuity indication is required, including automotive, fire alarm and solar / PV systems.
