Megger has launched the TPT320 two-pole tester, which is described as compact, convenient and versatile and is designed to provide electrical contractors with a safe and reliable way of checking AC and DC voltages from 12V to 690V.

TPT320 two-pole tester

Designed with safety in mind, the tester not only has a CAT IV 600V safety rating in line with EN 61010-1:2010; it also complies fully with the recently introduced EN 61243-3:2010 standard that specifically covers the safety of two-pole voltage testers.

To ensure that the TPT320 is fast and convenient to use, it includes both an LED display and an LCD panel. The LED display provides an instant at-a-glance indication of voltage in six steps, plus (in the case of DC voltages) polarity, while the LCD panel provides a three-digit read-out of the voltage being checked.

The tester also incorporates two red LEDs that light up when it is connected to voltages high enough to present a shock hazard; this feature remains fully functional even if the tester’s batteries are missing or completely discharged.

One advantage of the TPT320 can be seen when it is used for voltage checks on circuits that incorporate an RCD or have RCBO protection, as the tester does not cause these to operate and disconnect the supply.

While primarily intended as a voltage checker, the TPT320 offers additional functions. These include continuity checking with an acoustic sounder and for three-phase systems and phase rotation indication that does not require crossing of the test probes, which is often necessary with other types of two-pole tester. The TPT320 also includes a bright LED torch to aid safe working in poorly lit environments.
