The VC 252, like all devices in the VC-200 series, is optimized for educational purposes and offers a measurement function for 1.5 V and 9 V batteries.

The impressive, easy-to-read EBTN display is clearly visible in both bright environments and darkness. With a display diagonal of 7.9 cm (3.1 inches), all digits and symbols are presented significantly larger, which helps to avoid reading errors.

Depending on the selected measurement parameter, the correct connection of the measurement sockets is displayed, providing significant assistance to beginners and students to prevent misuse. If the device is incorrectly connected despite the display, an alarm sound will be triggered.

To change the battery or replace fuses, the housing must be opened. For safety reasons, the measurement leads should not be connected during this process. This measuring device is designed so that the housing cannot be opened while the measurement leads are connected. The measurement leads can only be reconnected after the housing is closed, as the measurement sockets are mechanically locked.

The measurement lead is double insulated in two colors. If the first layer of insulation is damaged, a differently colored insulation layer becomes visible, which is ideal for training devices to facilitate the early replacement of worn measurement leads.

This device features a self-resetting fuse for the measurement range up to 600 mA, eliminating the need to replace expensive high-performance fuses. This is particularly advantageous in an educational setting. If the multimeter is still connected to a high-energy power supply in the µA and mA range, an additional glass tube fuse will activate to protect the self-resetting fuse from overloads.
