Set the programming resistors to the desired resistance and
turn the power supply on. Adjust the resistors to change the
power supply output.
The analog control circuits let you set the output voltage and current
limit up to 5% over the model-rated maximum value. The power
supply will operate within the extended range, however it is not
recommended to operate the power supply over its voltage and
current rating, and performance in this region is not guaranteed.

The J1 connector also provides analog signals for monitoring the
output voltage and current. Selection of the voltage range between 0
– 5 V or 0 – 10 V is made by SW1 setup switch 4. The monitoring
signals represent 0 to 100% of the power supply output voltage and
current rating. The monitor outputs have a 500 Ω series output
resistance. Make sure that the sensing circuit has an input resistance
greater than 500 kΩ or the accuracy will be reduced.
