Great value and accurate enough for insulation tests
This is a great little instrument for the cost. I found it very accurate. Maybe not rugged enough for everyday use, but very accurate and great for testing quickly when you don't need to drag the expensive MFT tester out quite yet. I would recommend as a second insulation test instrument to an MFT. Buy a good zip up case for it large enough to take a few sets of leads. Edit- A year later I still tend to grab this meter first before my Megger MFT. Continually impressed by it.

Decent low cost insulation tester plus
Works well at a decent price and also has voltage/continuity functions in addition to insulation testing at 3 different voltages. All good so far.

Preiswerte Fehlersuche Isolation
Top Gerät für diesen Preis. Tut, was es soll. Und das gut. Bedienungsanleitung sehr einfach gehalten. Aber wie bei Meßgeräten allgemein: man sollte schon wissen was man tut.
