The footswitch controls work as follows:

 SCAN mode: Pressing the footswitch will start and stop the SCAN mode (same as manually

pressing the front panel SCAN button).

 CHANNEL mode: Pressing the footswitch will change the channel from A to B or vice versa.

 RANGE mode: Pressing the footswitch will change to the range set when the mode is selected

(i.e., set the range to 3V, 10K, 200Hz, select footswitch RANGE mode; pressing the

footswitch will automatically change the Tracker to this range). This is useful for changing to a

favorite range by simply pressing the footswitch.

Press the MODE button to return to the Control menu or press the front panel MENU three times to

return to the power-up menu.

CONTROL – DIAGS Controls

The Tracker 2800/2800S has built-in diagnostics to ensure that the unit is functioning properly. The

diagnostics can be accessed through the touch screen menus.

To access the diagnostics menus, press the MENU front panel button to display the Main menu. Press

the CONTROL button (left image in figure 2-29) to display the Control menu. Press the DIAGS

button (center image in figure 2-29) to display the Diagnostics menu (right image in figure 2-29).

Figure 2-29 Control – Diags menus

Press the START button to display a diagnostics selection menu (shown in figure 2-30).

Figure 2-30 Diagnostics selections

 ALL: Executes all diagnostic routines

 LOOP: Executes the loop compensation routine that will “zero out” added capacitance on the

test line from attached cables.

 RES: Executes the resistor diagnostics. Tests the front panel resistance values with internal

reference resistors.

If any diagnostic routines fail, ensure that any cables attached to the front panel are removed and run

the diagnostics again. If failures continue to occur then contact Huntron Technical Support for

assistance.

In the Diagnostics menu, pressing DEFAULT will set the Tracker touch screen menus to the factory

default settings.

Pressing the WAVE button will change the Tracker to waveform display as shown in figure 2-31. This

button will change to SIG when waveform mode is enabled. Press SIG to return to signature mode.

Waveform mode is primarily useful when diagnosing problems with the Tracker.

CONTROL – 2000 Mode

The Tracker 2800/2800S can be set to display three of the ranges used with the popular Tracker 2000.

To enable 2000 mode, press the 2000 button in the Control menu. The display will change to the

Tracker 2000 ranges as shown in figure 2-32.

Figure 2-32 Tracker 2000 mode

 LOW range: 10V at 54

 MED1 range: 15V at 1.2K

 MED2 range: 20V at 26.7K
