Specifications are from Huntron and may vary slightly due to upgrades, options, or revisions this unit may or may not have. Comes with a power cord and common test leads. The unit is guaranteed to work for 30-days, parts and labor, excluding freight! According to the internet, the B version changes the 400 Hz supply to a 200 Hz supply. The top of the unit and the side are discolored/faded. The Unit's Serial Number Tag Reads: Model Number: 2000B Serial Number: 22B 01819 Sophisticated Electronic Troubleshooting: Test components and boards without power - ideal for catastrophic failures Get a picture of a component's overall health - including intermittent problems Test gate-fired devices with a built-in pulse generator Non-destructive testing. The Advantages of Tracker Technology: The Huntron Tracker 2000 provides advanced troubleshooting capabilities to simplify testing newer technology components such as CMOS and MOS circuits. Its built-in pulse generator lets you thorougly troubleshoot gate-fired devices such as SCRs, TRIACs and optocouplers. By energizing the gate, you can test a component in an active mode. You use a Tracker 2000 while the power to the circuitry you're testing is turned off. So you avoid an accidental short that could cause further damage. It allows you to analyzer the overall health of a solid-state component, which makes it perfect for finding leakage or substrate damage that has brought a system or PCB down prematurely. Because it can compare suspect components to known-good equivalents, it's also ideal for troubleshooting when documentation is missing or incomplete. Analog Signature Analysis: The Tracker works by applying a current-limited AC signal across two points of a component. The current flow causes a vertical deflection of the CRT trace, while the voltage causes a horizontal deflection. Together, they give you a unique current-voltage "analog signature" that represents the overall health of the device you're testing. Analyzing each signature, you can quickly tell if a component is good, bad or marginal. Real-World Troubleshooting Challengers: The Huntron Tracker 2000 is ideal for troubleshooting Programmable Logic Controls (PLCs). In troubleshooting multi-channel input modules, technicians frequently run into a damaged channel because the IC buffers, optocouplers and drivers have been over-stressed. By using the pulse generator built into the Tracker 2000, you can quickly troubleshoot optocouplers and other gate-fired devices. Simply compare signatures of one channel outputs with the Tracker 2000. These devices usually fail when too much current is drawn through the logic section. To troubleshoot them, compare the signatures of ICs in one channel against those in another, looking for differences that indicate a problem.
