Allgemeine Hinweise
General Notes
Vor dem Öffnen des Gehäuses den Netzstecker ziehen!
Before opening the cabinet disconnect the mains plug!
Achtung: ESD-Vorschriften beachten
Attention: Observe the ESD safety regulations
Leitungsverlegung
Bevor Sie die Leitungen und insbesondere die Masseleitungen lösen,
muss die Leitungsverlegung zu den einzelnen Baugruppen beachtet
werden.
Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder
in den werkseitigen Zustand zu versetzen um evtl. spätere Ausfälle
oder Störungen zu vermeiden.
Wiring
Before disconnecting any leads and especially the earth connecting
leads observe the way they are routed to the individual assemblies.
On completion of the repairs the leads must be laid out as originally
fitted at the factory to avoid later failures or disturbances.
Carrying out Measurements
When making measurements on semi-conductors with an oscilloscope, ensure that the test probe is set to 10:1 dividing factor. If the
previous measurement was made on AC input, please note that the
coupling capacitor in the oscilloscope will be charged. Discharge via
the item being checked can damage the components.
Durchführen von Messungen
Bei Messungen mit dem Oszilloskop an Halbleitern sollten Sie nur
Tastköpfe mit 10:1 - Teiler verwenden. Außerdem ist zu beachten,
dass nach vorheriger Messung mit AC-Kopplung der Koppelkondensator des Oszilloskops aufgeladen sein kann. Durch die Entladung
über das Messobjekt können Bauteile beschädigt werden.
Measured Values and Oscillograms
The measured values given in the circuit diagrams and oscillograms
are approximates!
Messwerte und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!
