Multimeters

Article (4)
  • The significance of True RMS
    The rapid changes in technology have meant that methods previously used for testing equipment are no longer accurate in many cases. Because an electrician comes across new technology on a regular basis, not to have a True RMS (root mean square) meter can be compared to a boxer going into a fight with one arm tied behind his back. In this article, Phil Collins, Engineering Support Manager, Techtronics Australia, explains what True RMS (TRMS) is and how to find it.
  • Assessing the true cost of test equipment
    In these austere times, management is being forced more than ever before to keep expenditure under control. Cuts have been made to company staffing levels, marketing budgets and in a number of other areas. If these technology enterprises are to survive though, they cannot afford to compromise on product/service quality, which means that choosing the right test equipment is more important than ever.
  • Think safety when selecting a multimeter
    Would you use the nearest handheld multimeter to measure mains voltage or some other high-energy source? Absolutely not! Just as different types of helmets are designed to protect against rockclimbing, bicycle and motorcycle accidents; different multimeters are designed with different levels of protection against common electrical hazards. For your own safety - and for the safety of others nearby - choose the right multimeter that’s designed to protect against specific hazards that will be encountered.
  • The smart buyer’s guide to test and measurement equipment
    Unfortunately, many people base their test and measurement equipment purchasing decision on price, availability and misleading sales information.
Feature (1)
  • Let's be accurate about tester accuracy
    There’s no doubt that test equipment needs to be accurate, as inaccurate test results can lead to potentially dangerous electrical systems being certified as safe. The way that instrument accuracy is specified, however, is not always as straightforward as it might seem.
