Six new compliant versions now available featuring extensive range of functions.
Weidmüller has introduced six new versions of two-pole voltage testers that more than fulfil the revised standard for these types of testers ie. DIN VDE 0682-401:2011 and DIN EN-61243-3:2010).
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. 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.
The standard covering two-pole voltage testers calls for a variety of changes – amongst others, these affect the protection class, the voltage category, and climatic conditions, as well as EMC compliance.
Weidmüller’s new testers are not entering the market, as required by the revised standards, with a minimum degree of protection of IP54. They offer more in that they are rated to IP65, which means they are effectively sealed to offer protection against the ingress of dust and offer all-round protection against jets of water – a very high degree of protection.
The two-pole voltage testers Digi-Check Pro, Digi-Check, Multi-Check, Combi-Check Pro and Combi-Check are CAT IV – 600 V instruments while the Master-Check belongs to the category CAT IV – 400 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 the 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 Digi-Check Pro, Digi-Check and Multi-Check are equipped with a large LC display, including bargraph; the display of the Combi-Check Pro, Combi-Check and Master-Check incorporate a row of LEDs.
In addition, a light sensor in the testers with LC display activates the background lighting only in dark surroundings to increase the service life of the battery. There is also a white LED which brightly illuminates the measuring point – in contrast to yellow LEDs, white LEDs enable colours to be recognised more easily – and they consume less power. Moreover, when measuring and testing points with a poor line of sight, the ‘Hold’ function makes it is possible to hold and read measurement values later on.
A two-pole phase sequence test function provides direct indication for both clockwise and counter-clockwise rotation. Depending on the version, the large measuring range covers 400, 500 or 690 V – with direct and alternating currents recognised automatically.
All the two-pole voltage testers automatically recognise the type of voltage (AC/DC) under test and indicate polarity. As well as phase-testing to earth, continuity and semi-conductor tests – possible using only one hand – also belong to the indispensable spectrum of tests. High input resistance ensures safe touch protection.
Load connection and RCD tripping prove particularly easy when utilising 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 personalised with an electrician’s name, an inventory number or similarly useful information.
The two-pole voltage testers from Weidmüller offer the high quality of being ‘Made in Europe’: the housing shell is manufactured in Germany, the printed circuit boards of the electronics are soldered in Switzerland by means of surface mount technology (SMT) and the final product is assembled in Europe.
The proven Weidmüller voltage testers LSP 3 – 400 V, LSP 3 – 690 V, Car-Check and Volt-Check 3.1 continue to successfully round off Weidmüller’s portfolio.
