Setting Up the System

Selecting the Setting used at Power-On

5.5 Selecting the Setting used at Power-On

This parameter selects the instrument setting that is used at power- on.

1.Press SYST repeatedly until P ON SET is shown at the bottom of the display.

2.Use Modify keys to select the setting.

LAST is the setting that was in use when the instrument was switched off.

DEFAULT is the default setting.

a number is the number of the setting location where the user has saved a setting.

Resetting the Power-On Setting

To reset P ON SET press and hold SYST until the value resets (this takes approximately two seconds).

PON SET is reset to LAST.

5.6Locking Out ENB/DIS

This selects how the shutter enabling and disabling key operates while the instrument is being operated over the GPIB.

1.Press SYST repeatedly until SHUTTER is shown at the bottom of the display.

2.Use Modify keys to select the setting.

NORMAL means that the shutter can be enabled and disabled as usual with ENB/DIS.
