CurveScope
Description of the CurveScope (CS) VI Tester
With our CurveScope (CS-1) VI tester device, you can see the VI compensation curve measurements of components (resistors, diodes, zener diodes, capacitors, integrators, transistors, coils, etc.) on electronic boards (PCB). With CurveScope (CS), you can apply specific voltage (Vpp) and low current signals to the terminals of the components and see the VI (Voltage/Current) impedance curves on the screen. By interpreting these curves, precise measurements can be made to determine whether the materials are defective or not.
With CurveScope (CS-1), it is possible to perform robustness tests of materials such as resistors, diodes, zener diodes, capacitors, integrators, transistors, transformers, etc. on the PCB without applying energy to the electronic board.
CurveScope (CS-1), thanks to the potentiometer on it, you can change the amplitude of the curves to a certain extent. In this way, you can see the curves of materials such as high value capacitors (470uF, 680uF, 1000uF, 1500uF).
CurveScope (CS-1), thanks to its 2-channel feature, comparative measurements of the components on the intact board and the defective board can be made.
CurveScope (CS-1) makes your work easier and helps you make faster, healthier measurements.

General Usage Information:
When measuring electronic boards, use the ESD wristband supplied with the CurveScope, attach it to the ESD port on the front of the device, and it will help to avoid any other malfunction due to static on the electronic board. Make sure that the area you are using has good grounding.
When using the CurveScope (CS) diagnostic tool, initially try to find faults by comparison. You can see the differences by checking the materials on the intact electronic board and the defective electronic board. Or you can compare the good components with the faulty components.
The impedance curves from the components on the board may show different impedance curves around the component due to other connected components.
After a certain time, you can easily distinguish between the graphs of intact and defective materials by looking at the curves. VI (Voltage/Current) impedance curves are important in fault detection. With our device, you can see VI (Voltage/Current) curves and make comments for fault detection.
When measuring the electronic board, use the ESD wristband provided with the CurveScope device, attach it to the ESD input on the front of the device, it helps to prevent another malfunction due to static on the electronic board.
When measuring with the CurveScope (CS) device, make sure that the power on the PCB is cut off.
The capacitors on the electronic board must also be discharged.
When the CurveScope (CS) is first turned on, the High voltage level is locked. When measuring in the high voltage range, attention should be paid to the specifications of the components.
When measuring any component with the CurveScope (CS) device, the reverse voltages of the components should be taken into consideration and the voltage level should be selected accordingly.
Make sure that the places that need to be isolated are isolated.
Brief information about the components to be measured:
If the resistance to be measured is large and the VI (Voltage/Current) curve is close to the horizontal axis, it is switched to low current and a clearer image is obtained. In the opposite case, that is, if the VI (Voltage/Current) curve is close to the vertical axis, it means that the resistance value is low and a clearer image is obtained by switching to high current.
The VI curves of capacitors vary according to their values. To see the capacitor curve more clearly, test at low current if the value is low and at high current if the value is high. If the capacitor value is at high current and in the form of a thin ellipse on the vertical axis, you can see its value more clearly by lowering the frequency from the frequency mode. You can also adjust its width with the potentiometer in our device.
Integrated legs are usually in the form of two reverse diodes. A single diode can be seen at the outputs of some integrals (except for the supply and ground legs). Curves in the form of resistance usually indicate that the integrated is defective. In such cases, clearer results are obtained by comparison. The point to be considered in components such as integrals is not to give too much voltage.
