The 98-0315 Footswitch will allow you to control Tracker functions such as channel selection, range setting and increment pins (Tracker 3200S and 2800S) while using handheld test probes or clips. Used with the Huntron Workstation software, it will allow you to increment tests using the manual test probes where your hands are not free to access the PC keyboard or mouse. This Footswitch will work with the Tracker 3200S, Model 32, Tracker 2800/2800S, Tracker Model 30, and TrackerPXI.
