Description

Aktii&ge llschaft . 1 Skalenbeleud. stung bei tragbaren Mess, 4 nstrwientien. Bei tragbaren Meßinstrumenten, die eine Meßspannungleræeugen Aung-, erzeugen üssen,wiez. B.I, olationsmesser oder HolzfetichtOmessert'wer- den zur Spannungserzeugung meist elektrischeBatterienVerwen- det. Da die Batteriespannung während desBetriebesabsinkt, wird die' Meßspannung von Hand vorjeder Xesäung eingeregeltoder besser selbsttätig durch Stabilisierungsglimmlampen konstant gehalten. Manche Meßgeräte missen nun häufig an dunklen Orten verwendet . werden. Eine Skalenbeleuchtung durch Glühlampen würde die Meß- batterie zu stark belasten. So ist der die Messung Ausführende meist gezwungen, eine Taschenlampe mitzufünren was seine Arbeit behindert und erschwert. Nach der Neuerung werden nun die zur Spannungsstabilis ! erung vorhandenen Glimmlampen in der Nähe der Skala angeordnet, so dass sie diese beleuchten. Bei günstiger Anordnung der Glimm- lampe ist das schwache Glimmlampenlicht ausreichend um die : '.'"-'. -'''"' : Skala des Instrumentes ablesen zu können. Figttt zeigt in einem Beispiel die Anordnung von zwei Stabilisieru Skalenbeleuohtung. ", ""1 : : : :, ; " : ",'....

Die Glimmlampen 2 werden durch einen reflektierenden Schirm 4-nach oben hin abgedeckt, um den Beobachter nicht, zu blenden und werfen ihr Licht auf die Skala. Der Schirm 4 kann spiegelnd ausgeführt oder weiß lackiert sein. Actii & community . 1 Scale beleud. stung with portable measuring, 4 nstrwientien. For portable measuring instruments that have a measuring voltage Aung-, generate üssen, wiez. BI, olationsmesser or HolzfetichtOmessert'wer- the mostly electric batteries used to generate voltage. det. As the battery voltage drops during operation, the measuring voltage is adjusted by hand before each seeding or better automatically by stabilizing glow lamps constant held. Some measuring devices are now often used in dark places . will. Illumination of the scale by incandescent lamps would overload the battery. So is the one who carries out the measurement mostly forced to use a flashlight to do his job handicapped and difficult. After the innovation, they are now used to stabilize the voltage! eration existing glow lamps arranged near the scale, so that they illuminate them. With a favorable arrangement of the glow lamp, the weak glow lamp light is sufficient for the : '.'"-'.-'''"' : To be able to read the instrument's scale. Figttt shows the arrangement of two in one example Stabilizing scale illumination. ",""1::::,;":",'...." ..,:, "" ,,,: """.', I ' A measuring instrument with dial 1 and pointer 3 is drawn. The glow lamps 2 are covered at the top by a reflective screen 4 so as not to dazzle the observer and cast their light onto the scale. The screen 4 can be made reflective or painted white.

. Die Glimmlampen können auch direkt unter der Skala angeordnet werden und, diese von unten beleuchten. Die kala wird hierbei aus mattiertem durchscheinenden Glas oder Kunststoff hergestellt.. The glow lamps can also be arranged directly below the scale and, illuminate them from below. The scale is made of matted translucent Made of glass or plastic.

Die Anwendung der Neuerung ist besonders bei Isolationsmessern von Vorteil, da diese häufig bei Instalbionen in dunklen Keller- oder Speicherräumen und Kabelschächten oder in Trafo-Stationen verwendet werden. Auch bei anderen Meßgeräten, z. B. beim Barkhausen-Geräuschemesser für akustische Messungen von Störgeräuschen in der Nacht, lässt sich die vorgeschlagene Neuerung anwenden. The application of the innovation is especially for insulation knives from Advantage, as these are often used in instalbionen in dark basement or storage rooms and cable ducts or in transformer stations. Also with other measuring devices, z. B. the Barkhausen noise meter for acoustic measurements of background noises at night, the proposed innovation can be applied.
