CHANGING THE INPUT SENSITIVITY

CHANGING THE INPUT SENSITIVITY (V/Div)
Press the 'MODE' button repeatedly until the 'V/div' settings First press the „mode" key Use up/down cursorkeys
appear. Use up/down cursorkeys for changing the input for changing the input sensitivity (V/div) (Fig 5.0)

Keeping the 'Up' or 'Down' button pressed for a long time
enables autorange. Keeping the 'Up' or 'Down' button pressed for a long
time enables autorange.
Remark:
When autorange is enabled (t/div and v/div are highlighted),
it will be disabled as soon as the 'Up' or 'Down' button is
used into V/div, t/div or Y-pos - mode.

CHANGING THE TIMEBASE (t/Div)
Adjusting the time base will visualise more or fewer periods of a
signal (t/div = time per division). Set the time base between 1h
and 0.2µs per division.
Press the 'MODE' button repeatedly until the 't/div' settings
appear.
Press the 'up' or 'down' cursor keys to increase or decrease the
timebase (time/div).
Note:
•
Changing the timebase or sensitivity switches the
autorange mode immediately off. (Fig 8.0)
•
At higher timebase (2us and faster) the scope uses
oversampling mode, only repetitive signals are correctly
displayed.
•
Use the minimum time base (0.2 microsec) as a starting
point when measuring a signal and select longer time
bases until the signal is displayed properly. Otherwise the
display may not correctly reflect the signal under
measurement due to aliasing.
•
Keeping the 'Up' or 'Down' button pressed for a long
time enables autorange.
•
When autorange is enabled (time/div and V/div are
highlighted), it will be disabled as soon as the 'Up' of 'Down'
button is used.
