"Das Multimeter ist richtig gut verarbeitet und macht was es soll.Positiv: Batterie leicht einsetzbar, gefederte Aufstellklappe, geruchlose Schutzgummierung, genaue Messerte. gute AblesbarkeitNegativ: (deswegen 1 Stern Abzug) die mitgelieferten Messspitzen sind mittelmäßig und geben schlechten Kontakt, Aufbewahrungsbeutel fehltIch habe nun die Messspitzen gegen deutlich bessere mit Goldkontakten getauscht und nun liefert das Multimeter Spitzenwerte und der Durchgangsprüfer reagiert sofort auf geringsten Kontakt (sehr gut). Der Isolationswiderstand ist auf hohem Niveau und die Sicherungen sind mit Quarzsand gefüllt. So soll es sein.Ein empfehlenswertes Multimeter, jetzt fehlt nur noch der Dauertest"
