Troubleshoot low voltage logic circuitry without the possibility
Troubleshoot low voltage logic circuitry without the possibility of exceeding manufacturers voltage specifications.
The Huntron® Tracker 2700 extends the capabilities of power-off testing to troubleshoot low voltage logic circuitry. Its low voltage ranges also make it ideal for testing passive devices such as high value capacitors while still in-circuit. Source voltage, source resistance and test frequency is clearly defined on the front panel overlay. Using a power off test method known as Tracker Signature Analysis, it eliminates the risk of further circuit damage, which often occurs when power is applied.
Modern complex switching power supplies with failsafe protection circuits contain many passive components that are difficult to test in circuit due to parallel solid state devices. The 200mV range of the Tracker 2700 allows resistors, capacitors and inductors to be analyzed without turning on the parallel solid state devices. Today’s portable electronic devices use 3 volt or lower logic circuits.
The Tracker 2700 has 21 selectable voltage/resistance ranges available in 5 frequency groups resulting in a total 125 combinations of voltage, source resistance and test frequency.
Tracker 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 LCD trace, while the applied voltage causes a horizontal deflection. Together they form a unique V/I signature that represents the overall health of the device under test. Analyzing the signature can quickly determine whether the component is good, bad, or marginal.
