Coarse adjustment and fine adjustment
You can choose between coarse and fine adjustment
for some functions.
The fine adjustment is made using the right-hand rotary
knob or the two arrow keys below the display screen
Up
(increasing the value) and Down (reducing the value).
The coarse adjustment is made using the two arrow
keys below the display screen
Right (increasing the val-
ue) and Left (reducing the value). The value will then
change either in large increments (e.g. for the function
RANGE ) or you can choose from a series of factory-
saved values (e.g. for the function VELOCITY ).
During the fine adjustment, the name of the function is
displayed in lower-case letters (
range ), whereas it is
displayed in capital letters during the coarse adjustment
(
RANGE ).
Function HOME
You can or must select the function HOME in various
cases (e.g. to confirm certain settings). To do this, the
function
HOME must be assigned to one of the function
keys (see Section Assignment of function keys ,
page 5-7).
Choosing the start value
For some functions, you can quickly choose the start
value of the adjustment range. To do this, press the two
arrow keys below the display screen
Right and Left si-
multaneously after selecting the function. In this way,
you can e.g. set the value of the function
DISPLAY DE-
LAY to 0.000 µs.

ing functions:
