Press the MENU button until the power-up menu is reached (the signature will become live). The pins
can be manually scanned by pressing the PIN button on the LCD. Make sure you have a Common
connection to the PCBs being tested otherwise you will see only open circuit signatures (horizontal
lines) on the Tracker display. The display will change to show the current pin number at the top. Press
the and arrow buttons to step manually through the pins on the connected device with the
signature for each pin will be displayed on the LCD. Press A to view only channel A, B to view only
channel B or press the ALT button to view signatures on channel A and channel B. Comparison of the
A (green signature) and B (red signature) channels is automatic when the Tracker is in ALT mode.
Note the green “check” or red “X” mark on the bottom right portion of the LCD will indicate a passed
or failed comparison.
To scan without having to increment the and arrow buttons on the PIN menu, press the front panel
SCAN button and the 2800S will step through the pins automatically. Press the SCAN button again to
stop the scanning. By default, selecting the SCAN button will test each pin in each 2800S resistance
range before stepping to the next pin. To change which range parameter is scanned, press the front
panel MENU button to display the Main menu (left image in figure 2-15) on the LCD. Press the
SCAN button on the LCD to display the SCAN menu (middle image in figure 2-15) and press the
MODE button on the LCD to display the MODE menu (right image in figure 2-15). Use the and
arrow buttons to change the scan mode between resistance (RES), frequency (FREQ), none (NONE)
and voltage (VOLT).
