3.4.3 SETTING LOCAL MODE
When the power supply is turned on, it is automatically set to Local mode. If remote commands
are accepted over the GPIB bus, the power supply will automatically go into Remote mode (
Rem
at the upper left of the LCD). Pressing the LOCAL key will restore Local mode. When in Remote
mode, all keys except LOCAL are disabled.
The ATE-DMG incorporates a “keypad lockout” command which allows the LOCAL key to be
disabled during remote operation, preventing inadvertent setting of the power supply to Local
mode. If the keypad is locked, it must be unlocked either by a remote command (see Appendix
B, PAR. B.87), or cycling the power supply off then on.
3.4.4 ADJUSTING LCD CONTRAST
With the power supply in command entry status , press MENU key. Press
"
or
ç
key to
increase or decrease contrast for optimum viewing. The contrast can also be set directly by
entering a number from
1 to 9 . Press ENTER or CLEAR to exit menu.
3.4.5 ENABLING/DISABLING AUDIBLE BEEPS
With the power supply in command entry status , press MENU key three times. The top line
indicates if the speaker is on or off (the factory default setting is speaker on). Enter 1 to enable
the speaker, or 0 to disable the speaker. Press ENTER or CLEAR to exit menu.
3.4.6 ENABLING/DISABLING DC OUTPUT POWER
When the power supply is turned on, the output is automatically enabled, and the bottom line of
the LCD gives voltage and current measurements at the output. To disable the output, press the
red
OUTPUT ON/OFF key; the lower line of the LCD reads:
Output OFF
. When the output is
disabled, voltage and current are programmed to zero; the power supply remains in Command
Entry status. Pressing the
OUTPUT ON/OFF key again enables the output: the previously pro-
grammed values of voltage and current are restored and the LCD displays the mode (CV or CC)
and actual values of output voltage and current.
3.4.7 RESET
RESET overrides all other local commands to reset the power supply to the power on defaults:
output enabled, voltage mode, output voltage set to zero, output current set to a minimum value
