four arrow buttons once will cause the most-recently selected digit
to begin blinking, indicating the focus for editing the setting.
Once a digit is blinking, that place value can be incremented (in a
signed sense) by pressing [
], and decremented by pressing [
]. That
digit value can also be incremented by turning the
knob clockwise,
or decremented by turning the
knob counterclockwise. The selected
digit place can be changed by pressing either the [
] or [
].
The blinking function can be cancelled, and the display returned to
the display-idle state, by pressing [Cancel], or by briefly pressing the
knob inwards. When no digit is selected (blinking), turning the
knob will have no e

ect.
The arrow buttons are also used when navigating secondary instru-
ment settings, such as scan parameters.

Numeric Entry
The numeric entry keypad is used to directly enter voltage settings
to the DC205. Values are implicitly positive unless the [
+/
−
] button
is pressed, which will toggle the sign between positive and negative.
When entering a voltage setting through the numeric keypad, the
range limits are implicitly enforced during entry. This means, for
example, that when configured for the
±
10 V
range, the keypad will
not allow you to enter a value greater than 10.1 at any time.
