The VC 252, like all devices in the VC-200 series, is optimized for training and offers a measurement function for 1.5 V and 9 V batteries. It features an impressive, clearly readable EBTN display 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, helping to avoid reading errors.

Depending on the selected measurement quantity, the correct connection of the measurement sockets is displayed. This is a great help for beginners and students to avoid incorrect operation. If a faulty connection is made despite the display indication, an audible warning sounds.

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

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

This device features a self-resetting fuse for the measurement range up to 600 mA. The need to replace expensive high-performance fuses is eliminated with this variant, which is particularly advantageous in training. If the multimeter is still connected to a high-energy power supply in the µA and mA range, an additional glass tube fuse will blow to protect the self-resetting fuse from overload.
