The instrument switches automatically between CV and CC depending on the connec-
ted load. When CR is
, the instrument is not switched to CR mode automati-
cally, it operates in CR mode when sinking but source in CV or CC mode.
CV mode
shows that if the instrument is in the range of voltage regulation, the output

remains constant while the current may increase to its maximum value I
max
when the connected load is increasing. In CV mode, the font text in the channel display
