VI Curve Tester Description VI Curve Tester Features: VI curve analysis, also known as ASA, involves no circuit principle and does not require the circuit to be in a working state, making it ideal for fault detection of circuit boards that are detached from equipment, without the need for online detection. Absolutely forbidden to electrify or measure undischarged capacitance to ensure safety. Since the circuit board does not need power, it enhances safety. Device functions on the circuit board are not involved, allowing testing of any device types: digital, analog, digital-analog mixed, known or unknown (dedicated, programmable), etc. Testing is performed via circuit node (device pin), not limited by component packaging. ASA technology can also assess the quality of large-scale, complex, or unknown integrated devices, especially when other conditions are limited. Convenient and intuitive for detecting the function of discrete components. VI and Multimeter Resistance Method Type: Unlike multimeter resistance with low voltage, this instrument uses AC signals to evoke circuit nodes. Adjustable amplitude and frequency allow setting amplitude close to working voltage for more realistic measurements. Identify fault nodes through comparison. Component-friendly; limited current prevents damage or adverse impact. Proven fast and effective fault diagnosis technology. Specifications: 1.3 inch OLED display Built-in battery, 3000mAh 4-gear voltage adjustable (0.6V, 4V, 8V, 16V) 4 test frequencies (60Hz, 400Hz, 2000Hz) Curve movement: Yes Scan function: Yes True dual channel: Yes Simultaneous display: Yes Program control: Yes Host size: 14.5 x 8.2 x 4 cm Host weight: 218g Note: Discharge before measurement to prevent instrument damage. Package Includes: 1 x VI Curve Tester 2 x BNC cables 2 x Test leads 1 x Power cable
