Kenwood CS-4125 User Manual

In such a case, carry out adjustment again.
(7) TRACE ROTA Control
For adjusting the slope of the horizontal trace line. The slope of the line will
change due to such influences as the earth's magnetic force. Use a screw-
driver to keep the trace line parallel with the horizontal axis graticule.
(8) GND Terminal
This is the ground terminal to be used when setting up a common ground
with other equipment.
(9) * POSITION Control
For adjusting the vertical position of the CHI waveform displayed on the
CRT screen. During X-Y operation it is used to adjust the position of Y-
axis.
(10) VOLTS/DIV Control
For setting the vertical axis sensitivity with the CHI vertical axis attenua-
tor. It can be set in steps of 1,2 and 5. Setting the VARIABLE control all
the way to the right at CAL enables calibrated vertical sensitivity. During
X-Y operation, it becomes the attenuator control for the Y-axis.
(11) VARIABLE Control
For fine adjustment of CHI vertical axis sensitivity. Allows continuous
variable adjustment within the VOLTS/DIV range. When set to the right
at CAL, the attenuator can be calibrated. During X-Y operation, it
becomes the fine adjustment control for the Y axis.
(12) AC-GND-DC Switch
For selecting the CHI vertical axis input signal coupling mode.
A C I The input signal will be capacitively coupled, and all DC compo-
nents will be eliminated. The low range -3dB attenuation
point will be 10 Hz or less when using either a 1:1 probe or a
coaxial cable, and 1Hz or less when using a corrected 10:1
probe.
GND! Vertical amplifier input is grounded, and the ground potential
can be checked. At an input resistance of 1M O relative to the
ground, the input signal is not grounded. In this mode, the
anti-trace line jump circuit prevents the trace position from
changing suddenly when switching from GND to AC.
D C : Provides direct coupling of the input signal, and measurement
can be carried out with the direct current component intact.
(13) INPUT Jack
The CHI vertical axis input jack.
During X-Y operation, it becomes the Y-axis input jack.
