Turn on the ReFlex Power TM Controller. Insert the Power Test connector and
then the Control Test connector to turn on the FPDC output voltages. If the
Power Test Connector is not used, the connection leads must be short and the
sense leads connected to their respective voltages. Wait for 30 minutes for the
FPDC to warm up.
Connect the DMM across each of the four output voltages and verify the no load
output voltage is within specification. Add the load resistors to measure the load
regulation.
Connect the DSO across the leads to verify the ripple and noise specifications.
The return or sense lead must be as short as possible. Remove the probe tip and
use a short lead from the ground barrel to the return; also, measure right at the
connectors.
To check the output voltage turn on and off sequencing, connect one of the DSO
channels to each of the outputs. Removing and inserting the Control Test
Connector can verify the turn on and off sequence by observing the voltages.
