Ganzes

Das Gerät ist relativ klein und daher recht handlich, vor allem aber sehr Spannungsstabil. Ein Tragegriff am Gehäuse oben wäre vielleicht noch recht praktisch. Ich werde mir nach Ablauf der Garantie selbst einen montieren. Kann das Gerät nur weiter empfehlen.

Bin mit dem Gerät sehr zufrieden

Unerlässlich auch mal etwas prüfen zu müssen und dann ein ordentliches Gerät dafür zur Verfügung zu haben. Funktional gutes Gerät.

Praktisches Netzgerät

Gute Bedienbarkeit der Einstellräder und mit den farbigen Anzeigen super lesbar.
Alle Werte kann man einstellen wie beschrieben. Sehr leicht und handlich, so man kann es auch schnell mal einfach mitnehmen transportiern. Bin bis jetzt zufrieden.
