KEYBOARD FUNCTIONS
Delta Mode:
Increase or decrease voltage or current in user-selectable steps.
Store/Recall: Store and recall voltage, current and OVP levels from non-volatile memory
(25 memories).
Address Setting:
Set GPIB address.
Damping ON/OFF:
Sets current meter damping ON or OFF
Note: All voltage and current levels set via the keyboard are displayed on a separate 0·3” 4-digit
display. This entry preview system ensures that the user can observe the value entered before it is
effected thus avoiding possible error. The display is also used for setting additional functions. When
the output switch is on and no other function is selected, the display shows output power in Watts.

INTERFACE RESPONSE TIME
Remote Command
Processing Time:
Typically <50ms between receiving the command terminator for a step
voltage change at the instrument and the output voltage beginning to
change.
Power Supply: An internal time constant, T, (typically 22ms) governs the settling time
of a step voltage increase. Settling time to within 1% of the step
change = 4.6T, to 0.1% = 6.9T, to 0.01% = 9.2T; for example, after a
10V step the output will be within 1 digit (10mV = 0.1%) of its new
value in typically 150ms. For load current of 1 Amp or more, settling
times for downward steps will be very similar; however, response
times will be longer at low loads.
