The Auto-Set feature allows the Oscilloscope to measure and display unknown
signals automatically. This function optimizes position, range, time-base, and
triggering. It also assures a stable display of virtually any waveform. Auto Range is
especially useful for quickly checking several signals.
To enable the Auto-Set feature, perform the following steps:
1.
Connect the test probe to the circuit or device under test.
2. Press
the
AUTO SET
key; the test signals will appear on the screen.

ANGING
The Oscilloscope offers five (5) ranges that adjust automatically as measurements
are taken. Two numeric readings can be displayed:
MEAS SET1
and
MEAS SET2
(selectable independently); the measurements can be performed on the CH1 or CH2
waveform inputs.
To choose a frequency for CH1, perform the following procedure:
1. Press
the
MENU
key; the function menu will appear on the right side of the
screen.
2. Press
MENU
▲
or
MENU
▼
to select
MEAS SET 1
. Five selectable options
will then be visible at the bottom of the screen.
3. Press
the
F1
key and select
Freq CH1
from the root mean square (RMS)
option. The
MEAS SET 1
window color will change to red and display CH1
frequency.
To choose Peak-Peak measurements for the CH2 input, refer to the following:
1. Press
the
MENU
key; the function menu will appear at the right side of the
screen.
2. Press
MENU
▲
or
MENU

key to select
PK-PK CH2
from the Peak-Peak option. The
MEAS
SET2
window color turns to blue and displays the peak-peak value for the CH2
input.
