1.
Connect
a
suitable
load
to
the
output
and
turn
ON
the
output
by
pressing
the
“OUTPUT
ON/OFF”
button;
note
the
output
LED
indicator.
2.
Push
“Preset
1”
and
note
the
output
voltage
of
5V.
Press
“Preset
2”
and
note
that
the
output
voltage
rises
to
10V
in
5
seconds
showing
a
ramp
up
voltage
(the
output
will
remain
at
10V).
3.
Pressing
“Preset
1”
will
now
generate
a
ramp
down
voltage
from
10V
to
5V
in
5
seconds
and
will
remain
at
the
5V
level.
Note:
The
final
output
voltage
level
will
be
the
last
voltage
level
generated.
