Field Editor; Cursor Keys; Spin Wheel - Fluke 9640A Series Instruction Manual

Field Editor

There are two control sets for incrementally editing field data. They are the cursor keys
and the spin wheel.

Cursor Keys

The cursor keys are a group of four keys marked with right, left, up and down arrows:
(, , , ). These are the main editing keys for making minor changes in a field's
numeric data. Each press of  or  moves the cursor one decade to the left or right. Each
press of  or  increments or decrements the digit under the cursor by one. Using these
cursor keys in combination allows the user to edit/select any data in a focus field.
The data in the focus field reacts to the  and  keys like a counter. That is, as the
value under the cursor increases past nine (9), the number in the next higher decade
increases by one (1). Similarly, as the value under the cursor decreases past zero (0), the
number in the next higher decade decreases by one (1).
When the Instrument is in the operate mode ( light on), the RF Output responds
immediately to changes to its field values.

Spin Wheel

The Spin Wheel performs the same editing function as the  and  keys described in
the previous paragraph. However, as the wheel is spun, it continues to decrement (ccw)
or increment (cw) the digit under the cursor. This continuous spin-action is useful for
making larger changes to field values and for making real-time changes to the RF Output.
