NOTE Most keys provide a dual function or operation. The nomenclature on a key indi-
cates its unshifted function/operation, which is selected by pressing the key.
Nomenclature (in blue) above a key indicates its shifted function. A shifted func-
tion is selected by pressing the SHIFT key and then the function/operation key.
1 Special keys and power switch:
SHIFT Use to select a shifted function or operation.
LOCAL Cancels GPIB remote mode.
POWER Power switch. In position turns 2750 on (I), out position turns it off (O).
2 Function and operation keys:
