6. Voltage Measurement
Voltage is measured using a DC voltmeter.
Conditions of the measurement are the following:
Power Source..........................AC 220V, 50Hz
Receiving Signal.....................Colour Bar signal (RF)
All customer’s controls............Maximum positions

7. Number in red circle indicates waveform number.
(See waveform pattern table)
8. When arrow mark (
) is found, connection is easily found from the direction of arrow.
9.
: Indicates the major signal flow.
10. This schematic diagram is the latest at the time of printing and subject to change without notice.
Remarks:
1. The Power Circuit contains a circuit area which uses a separate power supply to isolate the earth connection. The circuit is
defined by HOT and COLD indications in the schematic diagram. Take the following precautions:
All circuits except the Power Circuit are cold.
Precautions:
All circuits except the Power Circuit are cold.
Precautions:
a
Do not touch the hot part or the hot and cold parts at the same time or you may be
shocked
shocked
b
Do not short-circuit the hot and cold circuits or a fuse may blow and parts may break
c
Do not connect an instrument such as an oscilloscope to the hot and cold circuits
simultaneously or a fuse may blow. Connect the earth of instruments to the earth
connection of the circuit being measured.
