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

You can use the resolution selection keys to move the blinking digit to the right 
or left when setting voltage.
