Luqeeg Dual Channel VI Curve Tester, ASA Tester, Circuit Board Online Detection with 4 Adjustable Frequencies & Internal Resistors, Ideal for Digital Analog Hybrid Devices

1. HIGH SAFETY: ASA test does not need to power the circuit board, does not involve the circuit principle, and does not need the circuit to be in working state 2. STRONG ADAPTABILITY: ASA testing does not involve the function of the device on the circuit board, so that can be tested no matter what type of device the circuit is composed of, including digital, analog, digital analog hybrid, etc. 3. FLEXIBLE AND ADJUSTABLE: The curve tester supports double channel signals input, four adjustable frequencies and four adjustable internal resistor 4. DOUBLE CHANNEL INPUT: VI curve tester support A or A+B channel display, B channel position can be adjusted, support Actuator signals output(5V) 5. 4 LEVEL TEST: VI curve test is simple, efficient and accurate, widely used, powerful, 4 speed frequency can be adjusted as needed, useful and practical Specification: Item Type: Curve Tester Voltage: AC2.7V Internal Resistor: 56Ω, 220Ω, 1KΩ, 20KΩ adjustable Frequency: 40Hz, 350Hz, 2kHz, 14Hz adjustable Size(LxWxT): Approx. 14 x 8 x 4cm / 5.5 x 3.1 x 1.6in How to Use: To power the device, use a DC 24V 1A power adapter with a DC 5.5x2.1 interface.
