General Directives

After repair in the primary circuits, make sure that you have
not reduced the creepage distances and clearances.
Before soldering, component pins must be bent on the solder
side of the board. Replace insulating guards and plates.
Safety Components
Components in the primary circuits are important to the safety
of the instrument and may only be replaced by components
obtained from your local service organization.
Check the Protective Ground Connection
Visually check the correct connection and condition and mea-
sure the resistance between the protective lead at the plug and
the cabinet. The resistance must not be more than 0.5 W. Dur-
ing measurement, the power cord should be moved. Any vari-
ations in resistance shows a defect.
