of the overvoltage/overcurrent protection can be delayed approximately 8 seconds after the out-
put is changed.
With the power supply in command entry status , press MENU key eleven times. LCD reads
Prot. Delay Count nn
where nn is the active setting. A count of 0 means no delay, a
count of 255 (highest value) means approximately 8 seconds delay (a count of 30 provides a
delay of 1 second).
3.4.11 CHANGING MAXIMUM VOLTAGE OR CURRENT VALUE
The maximum values of voltage and current are determined by the model, e.g., 25V and 40A for
the ATE 25-40DMG. These values can be lowered by the user, e.g., to prevent inadvertent dam-
age to a specific circuit under test. Changing the maximum values of the ATE 25-40DMG to 10V
and 1A, effectively makes the unit a 10V 1A power supply.
With the power supply in command entry status , press MENU key nine (voltage) or ten (cur-
rent) times. The LCD reads New MAXIMUM Vset (or Iset) nn where nn is the maximum
value setting to be changed. Press ENTER or CLEAR to exit menu without changing setting.
Press number keys to enter new value and press ENTER. Press ENTER again to exit the menu
and return to command status .
If a value is entered that is higher than the rated maximum for the power supply, the bottom line
of the LCD flashes Vset or Iset MAX = nn where nn is the rated maximum of the power sup-
ply. The unit remains in data entry status waiting for a value equal to or less than the rated
maximum. Press CLEAR to exit without changing the value.
Once the maximum value has been changed, if a value higher than the new maximum is
attempted to be programmed, the LCD flashes Vset (or Iset) MAX = nn where nn is the pro-
grammed maximum.
NOTES: 1. If the programmed output value is higher than the new maximum value established
with the MENU key, the output will be limited to the new maximum value.
2. The front panel CURRENT control provides secondary limiting. To disable limiting
from the CURRENT control, rotate fully counterclockwise.
3.4.12 STORING POWER SUPPLY OUTPUT SETTINGS
The programmed settings of voltage, current, overvoltage protection and overcurrent protection
can be stored in one of the 40 memory locations available for local programming (see PAR.
3.4.15).
With the power supply in command entry status , press STORE key. The LCD reads STORE
mem
nn where nn is the memory location where the settings are to be stored. Press ENTER
or CLEAR to exit without changing setting. Enter memory location (from 1 to 40) and press
ENTER. The programmed voltage, current, overvoltage protection and overcurrent protection
settings in effect when ENTER is pressed are stored in the selected memory location. To recall
stored settings, see PAR. 3.4.13
3.4.13 RECALLING STORED OUTPUT SETTINGS
With the power supply in command entry status , press RECALL. The LCD reads RECALL
mem
nn where nn is the memory location holding the settings to be retrieved. Press ENTER
or CLEAR to exit without changing setting. Enter memory location (from 1 to 40) and press
