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).

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.
Power On - presssing [ADJ] knob
Power Off - holding down [ADJ] knob for about 2 - 3 seconds
Frequently operated paramete rs are grouped into four catagor ies and governed by four buttons
respectively, as listed in the table below. When a parameter is se lected the corresponding
indicator is highlighted. Turning [ADJ] knob will change the paramet er.

4. About Rolling Display Mode
When Timebase is set to 0.1s/Div or slower DSO 094 enters . In
this mode traces shift (rolling) from right to left across screen to display slow signals.
