:Test point with a test pin.
Schematic Diagram Notes
1. Indication for Zener Voltage of Zener Diodes
The Zener Voltage of Zener Diodes are indicated as such on Schematic Diagrams.
Example:
(6.2V)......Zener Voltage
2. How to identify Connectors
Each connector is labeled with a Connector No. and Pin No. Indicating what it is connected to,
in other words, its counter part.
Use the interconnection schematic diagram to find the connection between associated connectors.
Example:
The connections between C.B.A.s are shown below.
