ow available from Martindale Electric – pioneers in test equipment – is the portable and sleek PD700 Proving Device, designed for the testing of contact voltage detectors up to 700V. With around 1000 electrical accidents at work reported to the Health and Safety Executive (HSE) each year and 25 resulting in death, there are simple precautions that need to be taken when working with or near electricity. The only way to offer complete peace of mind when it comes to your safety is to check your tester before and after you’ve proved the circuit to be dead with a Proving Unit such as the PD700 from Martindale Electric.. The PD700 Proving Unit from Martindale Electric offers users of voltage indicators enhanced operator safety as it can generate high voltages up to 700V but also lower voltages down to 50V which can still be potentially dangerous. Suitable for use with Drummond Test Lamps, Digital Multimeters and Low Impedance Voltage Testers to ensure they are working correctly, the PD700 also features an indicator which illuminates when lamps and voltage testers draw high currents.

Megger finds fault on cables of all types A
n ideal choice for electrical contractors who work on both power and communications installations, Megger’s new TDR1000/3 time domain reflectometer (TDR) can be used on an exceptionally wide range of cable types. It is suitable, for example, for use on low-voltage power cables, including modern concentric types, as well as on coaxial and twisted pair data and voice communication cables. Despite its versatility, the TDR1000/3 has been designed with speed and ease of use specifically in mind and it incorporates an auto set-up feature that makes it easy for even inexperienced users to obtain good results. And, for experienced users, this feature is a big time saver. Auto set-up automatically determines the impedance of the cable under test and sets the instrument accordingly, and also automatically selects the optimum gain and pulse width according to the range chosen by the operator. The need for manual setting is therefore eliminated, although a manual set up option is also provided for those who prefer to have full control of testing parameters.

New two-pole voltage testers from Weidmüller exceed revised standards requirements
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.
W 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.

eidmüller 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).
