PROGRAMMING MODE
Overvoltage and overcurrent values can not be changed using analog remote programming;
this can only be done by issuing a command via the GPIB or RS232 port, or via local mode from
the front panel (enter local mode by pressing the VOLTAGE and CURRENT adjustment con-
trols at the same time).
If the panel is locked and RS 232 or GPIB access is not possible, turn the power supply off, set
ANALOG I/O DIP switch position 5 to OFF, and then power up again to unlock the panel
(PAR.3.2.2.1). After the settings have been changed, turn the power supply off, set ANALOG
I/O DIP switch position 5 to ON to relock the panel, then turn on the power supply to restore
Analog Remote Programming (status display reads aRem).
