Heschen Rechthoek Comité Opgezette Huidige Meter Ampèremeter Tester DH-670 AC 0-30A Klasse 2.5 Ce vermeld

werkt uitstekend

Ich habe mehrere Anzeigen im Einsatz und bin sehr zufrieden.Hinreichend genau, Abweichung gering (max 1% / getestet mit professionellen Gerät)Ergo für den Preis einwandfrei.Hinweis: In dieser Ausführung ohne Spiegelskala.

Prodotto ottimo per il mio caricabatteria.

Tested this meter with a 10A load. My Digital-Multimeter showed 10A and the needle on the Heschen meter showed 10A. I view these as "Reference" meters so thats good-enough for me. Didn't have a wired meter to test accuracy at 20A and 30A, but I bought two of these meters, they both display 10A and 20A equally. I laser cut the mounting holes for them. I went by the dimensions shown on the product images. 49mm x 49mm for the 4 screws, and the 51.1mm diameter ( Which is on center to the 4 screws ). Meter was a snug-fit, but did fit. So, The dimensions are accurate. Satisfied with these meters for keeping a simple project, cheap!

The terminals are marked - and +, but I think that is just because this body type is reused for DC meters as well.It has a zero adjustment on front for the needle.The symbols weren't immediately clear to me. The zig-zag with line through it indicates this is a moving iron (iron vane) type meter, as opposed to rectified. The inverted T means it is mounted vertically.The class is for accuracy. 2.5 = (error/range) * 100. If I calculate it right the error should be within 0.75A.

Alles in Ordnung, sehr gut funktioniert es.
