All the above settings can be changed either by using the top cover-accessible switches while
power is off, or by sending SCPI commands if using digital control.
3.2.1 CHANGING THE DEFAULT POWER-UP SETTINGS
The default power-up settings listed in PAR. 3.2 can be changed as follows:
1. To change Load type, Trigger port pin 2 remote on-off logic or RS 232 baud rate, refer to
PAR. 3.3.2.1 for Reset Power-up.
2. To change all other power-up switch settings refer to PAR. 3.3.2.2 for normal power-up.
NOTE: All power-up settings can be changed by digital command, and if desired, the digitally
changed setting can be saved for power-up using the MEM:UPD command (see PAR.
B.12). However it is recommended that the unit be tagged with all settings saved for
power-up to avoid unexpected behavior upon power-up.
3.3 POWER SUPPLY BASICS
The following paragraphs describe basic operation of the front panel controls and indicators
(PAR. 3.3.1), how to turn the unit on, including how to change the power-up defaults (PAR.
3.3.2), and an explanation of the basic techniques and principles needed to operate the power
supply.
When in Voltage mode, the power supply will (within the configured and rated limits) provide the
programmed output voltage. Current is determined by the load, and cannot exceed the Current
Protect limits. If the protect limit is reached, the POWER/FAULT/LIMIT LED light changes from
green (power OK) to orange.
