NOTES ON SCHEMATIC DIAGRAM
R e s i s t o r :
To differentiate the units of resistors, such symbol as
is
used: the symbol means
ohm and the resistor with-
out any symbol is ohm-type resistor.
. Capacitor:
To indicate the unit of capacitor, a symbol
is used: this
means micro-micro-farad and the unit of the ca-
pacitor without such a symbol is microfarad. As to electro-
lytic capacitor, the expression “capacitance/withstand
voltage is used.
Temperature compensation
The indicated voltage in each section is the one measured
by Digital
between such a section and the chas-
sis with no signal given.
