Some current testers are designed for the low voltage range up to 1000 V, others for high voltage. Because modern voltage testers also function in a non-contact way, they are not only suitable for testing equipment that has been switched off, but also for checking during operation. This means it is possible to test the relevant circuits and systems without deactivating them. In addition to these applications, the test instruments are also used for the following tasks:
testing continuity,
determining rotating magnetic fields,
tests of residual current circuit breakers via the RC trigger function.
A non-contact voltage tester is suitable for determining the presence of voltage quickly. The meter is equipped with a sensitive probe that filters out high-frequency interference signals and allows a reliable indication of voltage. If voltage is detected, the instrument emits a clear warning signal, which can be visual and/or acoustic. Testo meters often have an integrated light. This means that they can, if necessary, work in a poorly lit environment. In order to be able to deliver precise measurements in difficult areas, testo Digital Multimeters are both watertight and dustproof, and comply with IP class 67.
The electrical field strength is detected directly on the conductor, via the non-contact phase tester and the associated sensor. There is also a warning signal if a specific voltage value is exceeded. A micro-controller integrated into the instrument is responsible for the corresponding analysis of the measurement data.
Two-stage setting in terms of sensitivity, for example:
stage 1 for phase detection,
stage 2 for voltage display.
A Non-Contact Volt Meter is a useful tool for detecting dangerous voltages quickly and for avoiding malfunctions. Regardless if you have switched the instrument on, pre-selected a 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 allowing for better safety. These measuring instruments must be easy to operate, to ensure that you are not exposed to any risk. Instruments, such as Testo Current / Voltage Testers 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.
Testo voltage tester are digital and contactless, suitable for several purposes. The instruments must determine whether a voltage is present in a specific electric circuit or system. The use of a voltage tester enables you to check whether the instruments are actually working in their environment or whether there is a fault source. This improves safety for upcoming work, for example if you commission equipment, or approach a power cable.
Testo Voltage Meters are characterized by their compact format and light weight. Depending on their design, Testo's voltage testers lightweight and feature intuitive operating controls. High-frequency interference signals are immediately filtered, and you also have the choice between two sensitivity levels. Testo Voltage Meters feature:
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.
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 LCD display. Additionally, you benefit from the anti-slip ring which optimizes the ergonomics of the meter.
When the voltage tester digital display shows readout, the built-in light can be very useful. In addition, you benefit from the robust housing which reliably protects from outside influences. Meets the DIN EN 61243-3:2010 guidelines.
Testo Electrical Instruments are suitable for a variety of applications:
continuity testing,
rotating magnetic field testing and
single pole phase testing.
