Verify that the power supply is in the constant current mode.
If you operate the power supply in the constant current (CC) mode, verify that
CC annunciator is lit. If the CV annunciator is lit, choose a higher voltage limit.
Note During actual CC operation, if a load change causes the voltage limit to be exceeded,
the power supply will automatically crossover to constant voltage mode at the preset
voltage limit and the output current will drop proportionately.
