5-7-4. Constant-current (CC) control with external voltage or resistance
It is possible to control the output current by external voltage or
external resistance through the connector J3 (EXT CONT) on the rear
panel if external control is selected in Section
“5-5-6. External control
(external voltage, external resistance)
” above. For the setting
procedures, see Section
“5-5-6. External control (external voltage,
external resistance)
”.
