2-6 Chapter 2: Basic Operation
Model 801GC, 801GF & 801GX¥Rev. A
Some of the image names in the main list may refer
to a sub-set of two or more different images. The
images in the sub-sets are selected by first selecting
the name of the desired sub-set from the main im-
age list. If the sub-set consists of just two images,
pressing the “Image” button will toggle between the
two images. The button is lit when the second im-
age is showing.
If the sub-list consists of more than two images, the
“Image” button is first lighted by pressing it one
time. The image knob can then be used to select
images from within the sub-set. The image name on
the LCD will not change. Pressing the “Image” but-
ton a second time will will return the “Image” knob
to normal operation.
❖ If there is only one test image associated with a
name in the image list, the “Image” button can
not be turned on for that image.
All of the built-in test images (and their uses) are
covered in detail in the “Images” chapter.
• A continuous cycling mode can be selected that
draws images one-after-another in an infinite
loop. This mode is activated by rotating the
image knob clockwise beyond the last image
in the image list about one turn. When acti-
vated, the message “Loop Enabled” is displayed
on the unit under test. After a second or two,
the first image in the cycle appears. Turning
the image knob counter-clockwise will stop
image looping.
The image knob performs other functions when the
801G* is operated in the either the test sequence or
programming modes. Please see the “Programming”
chapter for detailed information on operating the
801G* in the other modes.
