• You can move the cursor to carry out measurement in CURSOR mode.
• There are three types to select from:
1. VOLTAGE - press SELECT and COARSE TUNE on the front panel. The two cursor
positions can be adjusted with the multi-function control to measure rV. Choose
which cursor to adjust with the SELECT button. The displayed reading is the
voltage value between the two cursors.
2. TIME - press SELECT and TIME on the front panel. The two cursor positions can
be adjusted with the multi-function control to measure rT. Choose which cursor to
adjust with the SELECT button. The displayed reading is the time value between
the two cursors.
3. TRACKING - press SELECT and TRACK and when the waveform display is on the
cursor is shown tracking the changing signal automatically. Horizontal and vertical
cursors overlap to form a cross shaped cursor. It positions itself on the waveform
automatically. You can adjust the horizontal position of the cursor using the multi-
function control. The co-ordinates are displayed on screen. The measurement value
is displayed in the upper right corner of the screen.
Using the RUN button
• The RUN/STOP button indicates
the status of the oscilloscope.
If a green indicator illuminates
the status is 'running' and
the oscilloscope is acquiring
waveform, if the status is 'stopped' then it lights red and the oscilloscope is not
acquiring waveform and STOP appears on the screen.

Auto Setup

• Auto setup simplifies the operation. Press AUTO and the oscilloscope can
automatically adjust the vertical deflection factor and horizontal time base range
according to the amplitude and frequency of the waveform, and also ensure a
stable display of the waveform.
• When the oscilloscope is in auto mode the setup is as follows:
