HeizfadenSpannung Test.

Wenn der EHT-Transformator oder die Videokarte geändert wird, kann die Heizfadenspannung falsch sein.

Die Heizfadenspannung besteht aus Hochfrequenzbestandteilen. Genaues Messen der Heizfadenspannung kann nicht mit einem Effektivwertmeßinstrument erhalten werden. Ein Oszillograph mit Effektivwertmessen-Fähigkeit kann benutzt werden, um die Heizfadenspannung zu messen.

Obgleich ein Sichtprüfen der Heizfadenfarbe eine Anzeige der Heizfadenspannung ist, ist es gutes üblich, die Heizfadenspannung zu überprüfen, wenn es irgendeinen Zweifel ¸ber diesen wichtigen Monitorparameter gibt.

Der folgende Heizfadenspannung Test ist eine genaue Methode des Findens der zutreffenden Effektivwertspannung zum Heizfaden. Dieses wird vollendet, indem man die helle Ausgabe des Heizfadens vergleicht, wenn es durch den Monitor zur hellen Ausgabe des Heizfadens mit einer angewandten Gleichstromspannung mit einer einprogrammiert Fotozelle angetrieben wird.

Die Heizfadenspannung finden;

1.Löten Sie zwei kurze bussleitungen zu den Heizfadenanschlußstiften weich.

2.Benutzen Sie schwarzes Band, um die Fotozelle über der Bohrung im Plastik-CRT-Einfaßung Stecker zu sichern.

Vorsicht: Seien Sie sicher, die Fotozelle nicht zwischen die zwei Tests zu verschieben.

3.Speichern Sie die Gleichstromspannung, die von der Fotozelle mit dem Monitor ausgegeben wird, der normalerweise läuft. Der Monitor Muß laufen damit 10 Minuten die Heizfadenspannung messen.

4.Drehen Sie weg den Monitor Ab.

5.Schließen Sie die variable Spannung, 1 Ampere, Gleichstrom-Versorgung zum Heizfaden an. Das Negativ führen zu den Heizfaden, der am CRT-Einfaßung Anschlußstift 10 gerieben wird.

6.Stellen Sie die Versorgungsteilspannung auf das Fotozelle Messen ein, gespeichert in Jobstep 3.

7.Die gleichwertige Heizfadeneffektivwertspannung wird jetzt gespeichert, indem man die Gleichstromspannung an den CRT-Einfaßung Anschlußstiften 9 und 10 mißt.
