The Short Finder is easily understood by all levels of expertise, from novice signalmen to real experts. Can also be used as an insulated joint tester or to locate line and cable circuit shorts and identify high-resistance bonds and track connections, noisy air gap arresters etc. Is also commonly used as a track quality meter for gauging suitability of track conditions to support signal circuits. Many probe accessories are available to improve connection to the rail. Calibrated Test Loads also available that permit use of Short Finder to confirm resistance values of signal testing shunts.

324-18 Quick-Read Probe Tips
Quick-Read Probe Tips make using the Short Finder easier in rusty, greasy or contaminated rail environments. Instead of carrying a file, the hacksaw blade Probes scrape through the interfering material covering the rail, switch rods and gage plates, resulting in stable and reliable Short Finder readings. Screw onto threaded shoulders on the original leads furnished with the Short Finder.

324-28 Dual-Blade Probes/Leads Set
Dual-Blade Probes/Leads Set provides a mid-range alternative to our Quick-Read Probe Tips and the File Probes. The dual-blade configuration stiffens the assembly and the four inch handle allows some additional reach and mechanical advantage without adding significantly to the weight. A unique lead set screws into the handles of the Dual-Blade Probes. Take accurate Short Finder readings, easily through rust, grease and other rail contaminants. Leads are each four feet long, are made of low-temperature lead wire and are the same as those furnished with later-version File Probes. Set comes with Dual-Blade Probes and Screw-On Leads. Leads are replaceable.

Model 324-1XX Calibrated Shunt Test Loads
Permit use of Short Finder to check testing shunts for correct resistance. Calibrate the Short Finder on the 3.0KHz frequency and read between the "HW" terminals and the "0.06 Ohms" terminals. These readings are the values you should see when you check your testing shunt. If you do not see these values, your shunt should be repaired or replaced. Test Load can also be furnished for use with shunts with the following resistances: 0.10, 0.10, 0.25 and 2.0 ohms.

324-17 AC Adapter
This Adapter has been developed to convert AC voltages to DC, so that AC voltages can be read by the DC voltmeter built into the Short Finder. Because there is a significant loss across the Adapter, the resultant readings cannot be considered suitable for the purpose of obtaining data. However, they are entirely usable as indicators of the presence of distorting or damaging AC voltages, or for determining whether your track light is on due to an open or a short where conventional AC track circuits are used.
