Instruction for DR & PS Operation
a) Adjust the output voltage-1 to second place of decimal after switch off of Output Voltage-2. Monitor the output voltage on test points-1 at front panel.
b) Increase the load to 50% and 100% and note values Vo;;xx xx volts as desired.
c) Adjust the output voltage-2 to second place of decimal after switch off of Output Voltage-1. Monitor the output voltage on test points-2 at front panel .
d) Increase the load to 50% and 100% than note values Vo;;xx xx volts as desired.
e) Ensure that the two are matching with each other, as close as possible
f) connect the load at combined Output connector
