window segment decreases when the DELAY time coefficient is set to
a lower value (higher time deflection speed).
For better reading, the vertical position of the DELAY time base trace
position can be shifted (please note TRACE SEP (11)).
DELAY
In the DELAY time base mode, the display of the MAIN traces, the
window sector and the MAIN time coefficient will disappear from the
readout. As the trace separation is no longer required under the
circumstances, the function would be switched off too. Consequently,
only the DELAY time coefficient is displayed by the readout.
(23)H POSITION
The control knob enables a horizontal position shift of the signals. In
combination with ×10 MAG the function makes it possible to shift any
part of the signal on the screen.
(24)×10 MAG—SETUPS LOCK— Pushbutton has double function and
associated MAG LED.
Each time when this pushbutton is pressed, the MAG LED located
above will be switch on or off. If the MAG LED is lighted, the signal
display in all time base modes will be expanded 10 folds and
consequently only a tenth part of the signal curve is visible. The
interesting part of the signal can be made visible with the aid of the H.
POSITION control.
SETUPS LOCK
Pressing and holding the pushbutton, then switch the panel setups lock
function on or off. To avoid unintentional touch of the setting, the
feature is extremely useful for long term and repetitive measurements
that need to be performed under the same test condition of the
oscilloscope setting.

(25)X-Y-VAR – Pushbutton with double function.
X-Y
Set to X-Y mode to select three functions sequentially by pressing the
button briefly.
VAR
Pressing and holding the pushbutton to select the TIME/DIV (21)
control knob function between time base switch and vernier (variable).
The variable function is activated in the MAIN time base only.
After switching on the VAR, the time deflection coefficient is still
calibrated until further adjustments are made. Turn the TIME/DIV (21)
control knob counter clockwise to increase the time deflection
coefficient (reduce the deflection speed) and the deflection coefficient
becomes uncalibrated. Instead of “A=10μs”, the readout then displays
“A>10μs” indicating the uncalibrated condition. This setting is stored
if the instrument is switched to ALT or DELAY time base mode.
Switch off the VAR by pressing and holding the pushbutton of time
base mode again, then set the time deflection coefficient back into the
calibrated condition.
