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.
