Super for the tool box

The Duspol fits well into the toolbox. For most quick screening it is sufficient: Measure voltage (230V, 400V, nothing; is displayed in stages with LEDs), continuity test (also high impedance), phase sequence in three-phase sockets. By eingebauen vibration motor can safely go, that not only induces a voltage in the line. A RCD may be triggered. All this of course does not replace Installationsprüfgerät or multimeter, but is a good complement to this to protect the expensive meters. I saw him just lying in the tool box. It is rugged and a few scratches I do not care. For exact voltages i use a multimeter.
