Amplitude - Protek B8000FD Series Operator's Manual

Encoder knob clockwise while the frequency unit is blinking will
cause the frequency to increase by a factor of 10. Rotating the
Encoder knob counter clockwise will decrease the frequency by
a factor of 10.
Example: If the currently selected frequency is 1.0000000
KHz and the KHz units is blinking, rotating the encoder
clockwise 1 step will increase the frequency to 10.000000 KHz.
Rotating the Encoder knob counter clockwise 1 step will
decrease the frequency to 100.00000 HZ
A frequency value may also be entered using the keyboard.
Pressing a number on the key board will enter the keyboard value (the
previous digits will be cleared) and it will blink. An 8 digit value plus
decimal point may be entered from the Key board and all the entered
digits will be blinking. Pressing the Enter key confirms the new value
and the blinking will stop. NOTE: Pressing the ESC button at any time
while the digits are being entered (blinking) will cause the frequency to
revert back to its previous value.
If the frequency value entered from the keyboard or
encoder know is greater than the upper frequency limit of the
selected waveform, the frequency value will default to the
upper frequency limit of the selected waveform. (See the
specifications for this unit)
