Displaying CAL waveform by AUTOSET

If you are not sure about the amplitude or frequency of a signal, or how to operate the
scope, press the AUTOSET button. The scope then automatically sets the vertical,
horizontal and trigger condition for displaying the input signal.
(For details of AUTOSET, see the appendix 3.)

Execute Autoset
After the signal is input, press the AUTOSET button
first. Optimal setting according to the input signal is
automatically performed.
Holding down the AUTOSET button for 1 sec or
more allows the panel setting (setup) before
execution of AUTOSET to be restored.
The following procedure explains how to display the
CAL signal through the probe to CH1.
Select a probe to use for CH1 and attach the color
ring (e.g., orange). Keep the remaining color rings
as spares.
1. Connect the probe to the CH1 input terminal as
shown in the left figure.
2. Connect the arrow chip of the probe to the CAL
terminal and the earth leads to the ground
terminal.
The CAL signal is a 1 kHz square wave of 0.6 Vp-
p amplitude.
3. Select CH1 with the SELECT button. Press the
CH1 MENU button to display the CH1 menu.
4. Turn on TRACE to display the CH1 waveform
with [FUNCTION operation].
5. Set the coupling to DC with [FUNCTION
operation].
6. Set the Probe menu to Auto with [FUNCTION
operation]. This Auto setting converts and displays
the CH1 gain sensitivity automatically depending
on the probe attenuation ratio (10:1, 100:1).
7. Press the AUTOSET button. The waveform as
shown on page 13 appears (when CH2, CH3,
and CH4 TRACE are OFF).
