OLED Display 2 Channel Handheld VI Curve Tester ASA Circuit Board Online Repair Tester 4 Voltage 4 Frequency
Features 1 VI curve analysis also known as ASA does not involve circuit principle and does not require the circuit to be in working state so it can be used for fault detection of circuit board that are separated from equipment without online detection without drawing data It is absolutely forbidden to carry out electrification and measure the undischarged capacitance Since the circuit board does not need to be powered the circuit board is relatively safer It does not involve the functions of the devices on the circuit board so no matter what type of devices the circuit is composed of digital analog digital analog mixed functional known unknown such as dedicated programmable etc it can be tested It is tested by circuit node device pin and is basically not limited by the packaging of components on the circuit board As a single device can be regarded as the simplest circuit board ASA technology can also be used to detect the quality of large scale complex or unknown integrated devices In fact due to limited conditions ASA is the only way for many users to detect such devices In addition ASA is convenient and intuitive when it is used to detect the function of discrete components 2 VI and multimeter resistance method type but the multimeter resistance voltage is low and this instrument uses AC signal to evoke circuit nodes Because the amplitude and frequency are adjustable the amplitude close to the working voltage can be u
