• Time/div and Volt/div settings are displayed in a
normal font (not inverted)
• Cursor keys are set for changing the time base and
input sensitivity.
Note:
• Changing the time base, input sensitivity or trigger
mode turns off the auto range-mode.
CHANGING THE INPUT
SENSITIVITY
First press the „t-V/div“ key Use up/down cursorkeys
for changing the input sensitivity (V/div) (Fig 35)
Press the left/right cursorkeys for changing the
timebase (time/div). (Fig 36)
1. Changing Volt/div:
The signal on the screen can be enlarge or reduce
vertically by adjusting the displayed voltage per
division. (V/div = voltage per division). The divisions
can be made visible through the Display set-up key
(see display setup).
Select the sensitivity : from 5mV to a maximum of
20V per division.
F 50mV to 200V with X10 probe selection
Pressing the up cursor key increases the input
sensitivity (lower value for V/div).
Pressing the down cursor key decreases the input
sensitivity (higher value for V/div).
2. Changing the timebase:
Adjusting the time base will visualise more or fewer
periods of a signal (t/div = time per division). The
divisions can be visualised through the Display set-up
key (see display setup). Set the time base between 1h
and 0.2µs per division.
