Extremely robust multimeter. The Voltcraft VC-400 series is ideally suited for electricians, installers, and service technicians working in harsh environments. A number of features make this device the first choice for daily use. Tough and durable: A two-component housing with surrounding soft rubber protection shields the measuring device from all sides, as well as the display from damage when dropped onto hard surfaces. It can withstand falls from heights of up to 2 meters. Its rubberized casing also makes it very easy to grip. Water and moisture protection (IP65): The multimeter is designed so that rain, snow, or even a water jet will not cause it to malfunction. It can be used and stored in locations with high humidity, such as industrial sites, machine rooms, and not-so-dry garages, without any issues. Dust and dirt proof: The housing, sockets, and all controls are constructed to be completely dust-tight. Even after many years, the multimeter remains as functional as on the first day. Non-slip when lying down and opened: The Voltcraft VC-400 series maintains a non-slip contact with the surface due to its rubberized back. When opened, the device remains securely in place thanks to the integrated rubber surface in the stand. Accurate measurements through True RMS measurement: The True RMS measurement allows for precise measurement of asymmetrical voltages and currents that deviate from the fundamental sine wave shape. Asymmetrical voltages are often found in power controllers such as dimmers, speed controllers, pulsed switch controllers, pulsed chargers, or electronic speed controllers in model building. Conventional average-value measuring devices can show significant measurement deviations in these measurement tasks. Automatic display lighting: An integrated brightness sensor automatically activates the display lighting at dusk. Special attention has been paid to the contrast of the display.
