Description

Beim Messen in elektrischen Schaltungen verwendet man meist handliche Prüfspitzen, mit denen man auch an schwer zugänglichen Stellen messen kann. Vielfach verwendet man eine Prüfglimmlampe als Universalprüfspitzenindikator für höhere Spannungen. Man erkennt mit ihr die Art der anliegenden Spannung (Gleichspannung oder Wechselspannung), die Polarität von Gleichspannungen; geübte Personen können sogar die ungefähre Größe der Spannung feststellen. Außerdem stellt die Glimmlampe zusammen mit einer Stromquelle einen sehr guten Durchgangsprüfer für große Widerstände dar. When measuring in electrical circuits one usually uses handy ones Test probes with which you can measure even in hard-to-reach places. Multiple a test glow lamp is used as a universal test tip indicator for higher voltages. You can recognize the type of voltage applied (direct voltage or alternating voltage), the polarity of DC voltages; Experienced people can even use the approximate size determine the tension. In addition, the neon lamp together with a power source a very good continuity tester for large resistances.

T;F.ndungsbemäß ist die Meßinstrumentenprüfspitze nun so ausgebildet, daß in einer Prüfspitze eine kleine Glimmlampe mit ihrem hochohmigen Schutzwiderstand eingebaut ist, die bei Messung mit dem Meßinstrument durch einen einfachen Schalter überbrückt sind (vgl. Abbildung). T; F. According to the design, the measuring instrument test tip is now designed that in a test probe a small glow lamp with its high-resistance protective resistor is built in, which when measuring with the measuring instrument by a simple switch are bridged (see figure).

Damit ergeben sich folgende Vorteile: a) Prüfspitze und Glimmlampe sind in einem vereinigt; 1>) man erkennt die ungefähre Größe einer Spannung durch die Glimmlampe iind kann dann den entsprechenden Meßbereich des Instrumentes schalten; c) solange die Prüfspitze nicht durchgeschaltet ist, kann das Meßgerät nicht beschädigt werden, gleichgültig auf welchem Meßbereich es geschaltet ist; d) dadurch, daß die Glimmlampe nahe am Meßobjekt liegt, ist es leicht, Meßobjekt und Glimmlampe gleichzeitig zu beobachten. This results in the following advantages: a) Test probe and glow lamp are united in one; 1>) you can see the approximate size of a voltage the glow lamp can then switch the corresponding measuring range of the instrument; c) as long as the test probe is not switched through, the measuring device cannot be damaged regardless of the measuring range to which it is switched; d) in that the The glow lamp is close to the test object, it is easy to set the test object and the glow lamp at the same time to observe.
