4.2.5 Knob
The knob (SmartKnob) is located in the upper left-hand side of the instrument. Its
primary purpose is to adjust the selected instrument parameters. When the display
box of the parameter being adjusted is highlighted, rotating the knob clockwise
increases the value and rotating it counter-clockwise decreases the value. In some
cases, the knob may also be used to respond to various prompts from the instrument.
4.2.6 Hidden Function — Screen Capture
On the NORTEC 600 instrument, you can send a screen-capture image file to the
removable (external) microSD card by holding the MAIN FILTER menu key ( ),
and then pressing and holding the REF SAVE key ( ) until you hear a beep, after
which you release the keys. Alternatively, you can use the NORTEC PC software to
capture a screen image (see “Capturing a Screen Image Using NORTEC PC” on
page 300).
4.2.7 Knobless Entry
Knobless entry is an additional useful function in the NORTEC 600 main menu that
lets you change instrument’s settings (such as frequency, angle, and gain) in situations
when rotating the knob may be difficult.
When this feature is enabled, two additional key presses (UP and DOWN) are
available to change instrument settings (see Figure 4-7 on page 78).
