- Dual-Channel Design: This Handheld VI Curve Tester features 2 independent channels with alternate display function, allowing simultaneous comparison of component curves on circuit boards without switching leads, making troubleshooting more efficient for technicians working on complex electronic repairs and component verification tasks.
- Four Adjustable Frequencies: Equipped with 4-speed frequency conversion capability, this circuit board tester adapts to various testing scenarios by connecting to both analog and digital oscilloscopes, with adjustable alternating speed letting you customize testing parameters based on specific component characteristics and measurement requirements.
- X-Y Mode Oscilloscope Compatibility: Works seamlessly with oscilloscopes in X-Y display configuration, showing horizontal lines when probes are open and vertical lines when shorted under normal conditions, with built-in 103 potentiometer for fine-tuning curve display within 0.5-1 grid from frame For edge for optimal visualization.
- Precise ASA Testing Capability: This online tester analyzes analog signature analysis curves for rapid component comparison on powered-off boards, helping identify faulty resistors, capacitors, diodes, and transistors by displaying characteristic voltage-current relationships at measurement points without component removal.
- Safe Operation Guidelines: Before testing, discharge large capacitors on circuit boards to forestall damage to the VI board, avoid testing powered circuits, and use included BNC cables with leads for secure connections, with sturdy plastic housing measuring 195*135*105mm providing lasting portability for field service applications.
