Front Panel Test

Purpose

The front panel test checks the functionality of the instrument front panel keys and the RPG knob.

Test Setup

Press Measure, More (1 of 2), Front Panel Test. Once the Front Panel Test key is pressed you will see a display with three columns appear on the screen. The entries on the left side of each column describe a key. On the right side of each entry you will see a 0.

The front panel test requires you to press each of the front panel keys (in any order, with the exception of the ESC key, which must be pressed last), and to turn the RPG knob. The first time you press a key a 1 will replace the 0 that originally appeared to the right of the key column. Each additional instance of pressing a given key will result in an increment to the number listed in the column to the right of the key description. For example if you press the Zoom key four times, you will see a 4 to the right of the Zoom entry.

Rotating the RPG knob will result in a rapidly incrementing, or decrementing value appearing in the column to the right of the RPG Knob entry. Rotate the RPG knob clockwise and counter-clockwise. You will see negative or positive values appear, in ascending or descending order, depending on the direction you have turned the RPG knob.

Note that the two step keys (the up and down arrow keys) are described as the Rpg Dn and Rpg Up keys.

The ESC key must be pressed only after all other keys have been pressed and the RPG knob has been rotated; pressing the ESC key will cause the front panel test to be cancelled.
