TURN ON
At turn-on the splash screen below is displayed.
IMPORTANT!:
You should not attempt to measure voltages beyond 30Vp (=30V
DC
or 21V
AC
).If
you are unsure if the voltage you’re about to measure is within the limits of the scope, then don’t
measure it, or check with a multimeter first.
Also:
Never attempt to perform measurements on equipment that is powered from the
AC
grid
without a transformer, e.g. old TV sets, tube equipment, light dimmer circuits, etc… Usually, bat
-
tery operated equipment is safe.
1. Vertical divisions. There are 8 vertical divisions.
2. Trigger level and trigger slope.
3. Time/division setting.
When displayed in reverse video, automatic
time/division setting is active
4. Indicates whether the scope is in ‘
RUN’- or in ‘
HOLD
’-mode.
5. Input coupling (AC or AC+DC)
6. Volts/division setting
. When displayed in reverse video, automatic
volts/division setting is active
7. Horizontal divisions. There are 12 horizontal divisions.
8.
Measurements will be displayed here, when selected
9. Trace. The graphical representation of the signal at the input of your
scope. When there is nothing connected to the input of the scope,
the trace is more or less flat and centered.

THE TEST PIN
Connect the RED alligator clip to the pin marked ‘Test’.
TESTPIN
If your scope is working correctly, you should
see a square wave displayed:
Do not connect the
BLACK alligator clip.
The test pin provides a square wave output with a
frequency
of approximately 2kHz (2000Hz). Note that the
volts/div
and
time/div
settings have automatically changed, to ensure a correct
visualisation of the
signal
.
