3-12 OPERATING THE TESTER
Pin Contact Indicator The pin contact indicator shows when the probe has made contact
with a target pin. Target pins are pins that the operator has not yet probed. When the probe
contacts the pin, the pin contact indicator changes color and Digital Tracer makes a beep.
Digital Tracer cannot individually display all the pins for high density devices; therefore,
the pins for such devices are grouped with a single pin graphic. You may have to contact
two or more pins before the pin graphic changes. However, the pin contact indicator
changes state each time you contact a target pin.
Integrated Circuit (IC) Graphic
Devices are represented by a simplified line drawing.
Since every discreet pin of a large digital device may not be represented on a single video
image, rows of pins are represented as line segments which change color as you probe the
pins. Multiple pins can be
represented by a single pin graphic for large digital devices.
The example shows one pin per pin graphic.
