3.3.2 TURNING THE POWER SUPPLY ON
When the power supply is turned on, it performs a self-test and displays the status in the LCD.
After completing the self-test the LCD first shows the power supply type, e.g., Kepco ABC10-
10 GPIB addr. = nn, where nn is the GPIB address (factory default GPIB address = 6).The
LCD then shows the power on defaults (see Figure 3-1). The defaults are: output enabled, volt-
age mode, output voltage set to zero, output current set to a minimum value (1-2% of I
O
max).
Power on defaults also include setting maximum values for overcurrent and overvoltage protec-
tion indicated in Table 1-2.
NOTE: The power supply can be programmed to power up with output set to OFF. See PAR.
