POWER/INTENSITY
Turns the power on or off, and adjusts trace
brightness on the screen.
Clockwise adjustment increases brightness;
Counterclockwise rotation decreases brightness.
Pilot lamp
Lights when the power is on.
FOCUS
Adjusts focus grid voltage for clarity of the
display.
TRACE ROTATION
Corrects slight tilting of trace caused by
external magnetic fields.
INPUT
This is an input plug for use with the vertical
amplifier and Y-axis (vertical axis) amplifier
during X-Y operation.
Do not exceed the maximum permissible input
voltage, 600p-p or 300V (DC+AC peak)
AC-GND-DC
(Alternating Current-Ground Switch-Direct
Current)
Switches the coupling of the signal fed to the
vertical axis input
.
DC coupling is obtained
on the DC position.
On AC position, the direct
current component is blocked by a capacitor.
The GND position grounds the input of the ampli
fiers and opens the input terminal (J).
Position (PULL x5 GAIN)
it (Vertical position adjustment)
Clockwise rotation will move pattern up, and
counterclockwise rotation will move pattern down.
When the knob is pulled, the vertical axis
sensitivity at each range of volts/DIV is in
creased by 5 times.
VOLTS/DIV
This is a knob for switching the sensitivity of
the input signal fed to INPUT (s). Switching
action is accomplished in 10 steps from 5mV/DIV
to 5V/DIV.
On X-Y operation, the knob functions
to change the sensitivity of the Y-axis.
To measure by the use of the indicated voltage
sensitivity, be sure to set the VARIABLE
to
CAL by turning it fully clockwise (Click stop).
If the signal is applied to the input terminal
(J) by the use of a 1/10 low capacitance probe,
the values are ten times the indicated voltage.
