Press SET to exit from output settings mode.
Once in Set Mode (enter Set Mode by pressing the SET key), the active channel cannot be
changed. If Set Mode was inadvertently entered or entered in on the wrong channel, press the
SET key until the blinking cursor disappears to exit Set Mode (once out of Set Mode, active
channel switching is enabled).
Editing voltage and current values using the SET key cannot be canceled with the MENU key (the
values are immediately committed). Enter the old values by repeating the editing procedure and
manually using the
SET key: This key is active in any front-panel menu or display mode - if not already in the output
settings mode, the SET key will select it.
Pressing the SET key to exit the output settings mode returns the instrument to the previous
display mode or front-panel menu.
V and I DACs are updated in real time - if the output is on, the output is updated immediately when
a value is altered.
If the display mode is set to DUAL V AND I, then entering SET mode will cause the display to exit
back into the SINGLE V AND I mode for the active channel. If dual is desired, select dual after
exiting set mode (see
Editing shortcuts
The following editing shortcuts can be used when the output is OFF:
•
Output voltage can be quickly set to the maximum value by incrementing the tens digit
(MSD). Note that if the tens digit is zero, it is not displayed. Place the cursor to the left of the
units digit.
•
Output voltage can be quickly set to zero (0.000 V) by decrementing the first leading zero of
the reading. If there is no leading zero, decrement the tens digit.
•
Current limit can be quickly set to its maximum value by incrementing the units digit (MSD).
