AM700 Audio Measurement Set Service Manual
The measurement set is shipped from the factory with its touch screen fully
calibrated. Although it will seldom be necessary, the touch screen can easily be
recalibrated.
To calibrate the touch screen:
H Press the front-panel button labeled Other.
H Use the large control knob to scroll through the menu choices and select the
touch screen calibration choice from the menu that appears (see Figure 2–4).
Press Enter on the keypad to activate the selection.
The choice may also be made by touching the selection directly on the touch
screen interface, however, the above procedure can be used if the touch screen
should ever become uncalibrated.

Full instructions for calibration are given on the screen when the calibration
display appears (see Figure 2–5). A small circle with a dot is highlighted in
succession in each of three corners. View the screen directly on to avoid parallax
errors and use a small blunt pointed scribe, such as a pencil eraser tip, to produce
the best accuracy for the calibration. Touch the screen directly over the first dot.
The dot in the next corner then lights. Touch the second dot, then the third dot to
finish the calibration.
