A two-pole voltage tester is the only test instrument approved to determine safe isolation from the power supply that complies fully with occupational health and safety law. With its new two-pole voltage testers Weidmüller offers the electrical installation engineer a range of basic testing equipment that fulfils the requirements of the applicable standard. Today, all six Weidmüller versions already fulfil the revised standards for two-pole voltage testers (DIN VDE 0682-401:2011, DIN EN-61243-3:2010); all testers are TUV/GS certified. The revised standard for two-pole voltage testers came into force on 1st May 2010 - and took effect on 1s October 2010 with a three-year transitional period. The revised standard covering two-pole voltage testers calls for a variety of changes - amongst others, these affect the protection class, the voltage category, climatic conditions as well as EMC compliance. Weidmüller's new testers are not entering the market as required by the revised standard with a minimum degree of protection of IP54. Instead they are rated to IP65, which means they are effectively sealed against the ingress of dust and offer all-round protection against jets of water. Weidmüller's testers belong in the overvoltage category CAT IV - 600 V. As a consequence, as well as being suitable for measuring circuits electrically connected with a low voltage system they are also suitable for measurements in building installations. Moreover, the new voltage testers are all temperature-resistant from -15 °C to +45 C. To protect human health and the environment the requisite tests to guarantee electromagnetic compatibility were updated in compliance with applicable standards. Both top of the range versions Digi-Check Pro and Combi-Check Pro set the bar with regard to their range of functions; the other four versions Digi-Check, Multi-Check, Combi-Check and Master-Check focus more on functional highlights to offer an excellent price-performance ratio. Amongst other features the digital voltage testers are equipped with a large LC display including bargraph, offer test probe protection as well as a 'Hold' function; and to save battery power the background light is activated by a light sensor. All two-pole voltage testers automatically recognize the type of voltage (AC/DC) under test and indicate polarity. As well as phase-testing to earth, continuity and semi-conductor tests - possible with just one hand - also belong to the indispensable spectrum of tests. High input resistance ensures touch protection. Load connection and RCD tripping prove particularly easy when utilizing the top of the range versions Digi-Check Pro and Combi-Check Pro: simply pressing dual pushbuttons connects a load that can trip a 30 mA RCD or suppress an inductive reactive power. Actively connecting the load excludes the possibility of unintentionally tripping the RCD when testing. Last but not least, it is possible to fit snap-in markers to Weidmüller's voltage testers to allow them to be personalized with an electrician's name, an inventory number or similarly useful information.
