s
during setting operations and to increment numerical data. Holding
the button in while setting numerical data increases setting speed.
The down arrow serves two functions: to choose between
t
parameters during setting operations and to decrement numerical
data. Holding the button in while setting numerical data increases
setting speed.
Select
Places the instrument into settings mode where all instrument
parameters can be setup. When pressed while in the settings mode,
it terminates the settings mode without changing the existing
parameter value. Press and hold to display code revision date.

General Keypad Operation
The CYD211 has two keypad operations: setting selection and data entry.
Setting Selection: Allows the user to select from a finite list of parameter
values. During setting selection the s and t keys are used to select a
parameter value. Enter is used to accept the change and advance to the next
parameter. Select will cancel the change to that parameter and return to the
normal display.
Data Entry: Allows the user to enter numeric parameter values using the
s and t keys. Press the s key to increase the value of the setting, or press
the t key to decrease its value. Holding either key down for a few seconds
will cause the number to change at a faster rate. Once the correct parameter
value is entered press Enter to accept the change and advance to next
parameter. Pressing Select will cancel the change to that parameter and
return to the normal display.
Related setting selection and data entry sequences are often chained
together under a single setting sequence. To skip over a parameter without
changing its value press Enter before pressing an arrow key. To return to
the normal display in the middle of a setting sequence press Select before
pressing an arrow key. Changes "entered" before Select is pressed are kept.
