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
follwing precautions.
All circuits, except the Power Circuit, are cold.
Precautions
The circuit is defined by HOT and COLD indications in the schematic diagram. Take the
follwing 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.
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.
d. Make sure to disconnect the power plug before removing the chassis.
2. Following diodes are interchangeable.
