Instrument Overview

Numeric and Cursor Keys

The numeric keys are located in a block next to the LCD display. These keys are used for entering and manipulating data while in a parameter setup function:

Increment Up/Down: Use the increment up/down keys to increment an active parameter (up or down) and to move an active marker to the next step. The increment up/down keys allow you to increment or decrement the active parameter in coarse/discrete steps. These steps usually follow the 1, 2, 3, 5 convention. These keys are mapped to the Page Up/ Page Down keys on a standard keyboard.

Rotary Knob: The rotary knob functions much like the increment keys and can be used to adjust active parameters and move active markers. The rotary knob allows you to increment or decrement the active parameters with a fine resolution. The rotary knob is mapped to the up/down arrow keys on a standard keyboard.

Preset: Use this key to access the preset menu. The preset menu allows you to preset all of the instrument parameters to factory defaults.

Esc: Use this key to escape a function setup or parameter entry that has been initiated, but is not desired.

0,1,2...9: Use these keys for entering numerical values.

+/-:Use this key for changing a value’s numerical sign.

.: Use this key for entering a decimal point.

Back Space: Use this key for clearing an active entry.

Enter: Use this key for entering the data or executing a function.
