T POSITION Control
Rotation adjusts vertical position of channel 1 trace.
In X - Y operation, rotation adjusts vertical position of
display.

VOLTS/DIV Control
Vertical attenuator for channel 1 ; provides step adjustment
of vertical sensitivity. When VARIABLE control (3) is set to
C A L , vertical sensitivity is calibrated in 10 steps from
5 V/div to 5 mV/div.
For X-Y operation, this control provides step adjustment of
vertical sensitivity.

VARIABLE, PULL x 5 GAIN Controls
VARIABLE:
Rotation provides fine control of channel 1 vertical
sensitivity. In the fully clockwise (CAL) position,
the vertical attenuator
operation, this control serves as the Y axis at-
tenuation fine adjustment.
PULL x 5 GAIN:
When
pulled out,
multiplied by five and for X - Y operation, the Y-axis
sensitivity is multiplied accordingly. In x 5 GAIN
mode, the vertical gain is increased and the trace
becomes thickness.

AC-GND-DC Switch
Three-position lever switch which operates as follows:
A C :
Blocks dc component of channel 1 input signal.
GND:
Opens signal path and grounds input to vertical
amplifier. This provides a zero-signal base line, the
position of which can be used as a reference when
performing dc measurements.
DC:
Direct input of ac and dc component of channel 1
input signal.
(5)
INPUT Jack
Vertical input for channel 1 trace. Vertical input for X-Y
operation.

VOLTS/DIV Control
Vertical attenuator for channel 2; provides step adjustment
of vertical sensitivity. When VARIABLE control (7) is set to
C A L , vertical sensitivity is calibrated in 10 steps from
5 V/div to 5 mV/div.
In X - Y operation, this control provides step adjustment of
horizontal sensitivity.
