Huntron Shortrack model 90 User’s Manual (part no. 21-1186);
Rev 1, 1/98
INTRODUCTION
The Huntron SHORTRACK Model 90 is a short locating accessory for the Tracker line of Analog
Signature Analysis (ASA) instruments. A Tracker can detect that there is a low impedance fault
on a certain node of a PCB but it cannot always locate where the fault is. The SHORTRACK is
designed to pick up and give an indication of the current flowing through the fault so that it can
be followed and located.
The SHORTRACK can be used with the LOW range of the Tracker 1000, Tracker 2000 or
Tracker 5100DS. It is powered by a 9 Volt battery and has a LCD display with a fast responding
analog bargraph and a digital readout. An inductive probe is used to trace current flow in the
PCB.

Display:
The display is an LCD which consists of an analog display and a digital display:
The Analog Display is a 101 segment bargraph that simulates a meter movement. It is elliptical
in shape to allow the large number of segments to be displayed. The bargraph responds quickly
to signal changes and it can be understood directly so this is the primary means of tracing
current with the SHORTRACK.
