Modes & Menu
Y/T Mode
This is the most commonly used mode that
displays signal-to-time relationship.
Y/X Mode
This mode can be used to graph relationships
between two signals. In this mode Ch 1 becomes Y
and Ch 2 becomes X (see photo at right).
MENU
Menu is used to switch modes and perform special functions. Press [MENU] botton to enter menu
and press [HOLD] to execute selected item. Press [MENU] to exit.

4. About Rolling Display Mode

When Timebase is set to 0.1s/Div or slower DSO 094 enters
WARNING !
this mode traces shift (rolling) from right to left across screen to display slow signals.

5. Calibration of 10X probe

Please refer to the technical note "
Support/HowToCalibrate10xProbe.pdf) for details.

Basic Operations

First Time Powering UP
1 ) Unscrew the two screws at back cover. Remove back cover.
2 ) Battery was attached to the inner side of back cover. Insert its
connector to the header on PCB (marked as "BATT" at the side of
USB connector) as shown in the photo at right.
3 ) Put back cover back and screw it up.
- presssing [ADJ] knob
- holding down [ADJ] knob for about 2 - 3 seconds
