Testing the voltage with or without range pre-selection

A contactless voltage tester is a useful tool for detecting dangerous voltages in good time and for avoiding malfunctions. Irrespective of whether you have switched the instrument on, pre-selected the range or whether the battery is empty, the measuring instrument has to make the user aware of any possible danger. For the user, this means reliable protection against electric shocks and thus significantly better safety. These measuring instruments must be easy to operate, to ensure that you are not exposed to any risk. Instruments, such as Testo's current / voltage tester and digital voltage testers, are designed in such a way that there is no chance of any electric shock occurring if they are used properly. The instruments meet a high standard and have practical functions, such as:

• high-class fibre-optic,
• easily visible LED display,
• precise voltage indication.

Digital voltage detector – for the detection of interference signals and overloads

If a voltage tester works in a digital and contactless way, it is suitable for several purposes. The test instruments must primarily determine whether a specific voltage is present in a specific electric circuit or system. The use of a voltage tester therefore enables you to check whether the technical instruments are actually working in their environment or whether there is a fault source. This improves safety for forthcoming work, for example if you commission equipment or approach a power cable.

The voltage testers are characterized by their compact format and light weight. Depending on their design, Testo's voltage testers weigh a maximum of 230 g and score highly thanks to their intuitive operating controls. High-frequency interference signals are immediately filtered, and you also have the choice between two sensitivity levels. The following data are standard for Testo voltage testers:

• continuity testing less than 500 kΩ,
• rotating magnetic field testing 100 to 690 V,
• voltage range up to 1000 V,
• IP 67 (watertight and dustproof),
• setting options for phase detection or voltage measurement,
• visual and acoustic signal.

Testo test instruments for your safety

With a voltage detector from Testo, you get an innovative voltmeter which improves safety in a variety of areas. The clear, all-round display means you have no problems reading out the presented data from different positions. In addition, the reading that is currently determined is indicated on a second LC display. Furthermore, in terms of handling, you benefit from the anti-slip ring which optimizes the ergonomics of the handy test instrument.

When the voltage tester digital display shows how high the voltage is, the built-in torch can be very useful. In addition, you benefit from the robust housing which reliably protects the measuring technology from outside influences. Further important product details are the accuracy which meets the DIN EN 61243-3:2010 guidelines.

The measurement functions make Testo instruments suitable for a variety of applications:

• continuity testing,
• rotating magnetic field testing and
• single pole phase testing.
