Knowing what kind of formulas and functions to perform can also get overwhelming. The threshold is set programmatically in percentage terms. Printed circuit boards have many components, and know exactly which parts and materials are needed to repair or assemble a printed circuit board is essential. The criterion for the discrepancy of characteristics during automatic comparison is the excess of the threshold of tolerance of the measured R, C, U from the reference one. There is also a possibility to work without storing the reference data (using and applying the second probe in the same point on known-good board).Īssist-ASA operates with the characteristics presented in the form of graphical signatures and their corresponding numerical values (R is resistance, C is capacitance, U is voltage at the inflection point of the current-voltage characteristic). Reference characteristics are measure on known-good circuit and are stored in files in PC.

Troubleshooting of UUT is performed with parametric method VI (UI, ASA) by measuring volt-ampere signatures and impedance characteristic in the check points of the malfunctioning electronic module and then compare data to the reference points. If your printed circuit boards are down and you’re looking for the right way to get them going again, you’ve found it. It also provide conditions to make a repair of electronic modules quickly even if basic circuit diagrams are absent or not found. Curve tracer of voltmeter and impedance signatures Assist-ASA is a hardware-software complex designed for technical diagnosis and troubleshooting in electronic digital, digital-to-analogue and analogue circuits, modules and units using parametric method.Īssist-ASA has the possibility of troubleshooting (of microchips, transistors, capacitors, resistors etc.) on the board of unit under testing (here and after – UUT) without supplying it with feeding voltage.Ĭurve tracer can be used by staff without high qualification.
