GENERAL USAGE INFORMATION
1. Product Oscilloscope – Analog Output screen pop-up and if you click Fault Detector – VI Tester button,
input screen Fault Detect.  
2. Open circuit’s graph is in the middle and horizontal position at Test-Fault Detect screen. Current –
Voltage Graph (VI) makes angle according to the value of resistance, capacitor is like circle and ellipse,
short circuit is vertical position.  
3. Middle current step if resistance values are high and VI graph is horizontal axis, you can see more
clearly high resistance value at low current step. If VI graph is closer to vertical axis, it means resistance
value is low and values can be read more clearly at high current step.  
4. Usually, test capacitor at high frequency mode. If capacitor value is low, test at low current step and if
capacitor value is high, test high current step. If capacitor value is like slim ellipse at high current step and
vertical axis, you can see value of capacitor by reducing frequency of the frequency step.  
5. Good (solid) integrated pin (without pin of supply and ground) is usually like double reverse diode.
Resistor or capacitor effects even as graph, observed double reverse diode. Some integrated output can be
observed one diode. But, if you see pin of integrated like resistor, it means integrated is faulty.  
6. Capacity test especially determines quality of electrolytic capacitor. If this curve is horizontal, capacitor
is quality. Low quality capacitor curve according to horizontal makes an angle. If angle is more, capacitor
is faulty. Due to current this test may be misleading, while testing a capacitor at circuit. Therefore
considering this situation to test. For capacitor quality, the best measurement in this product is done by
looking at the Capacity Resistance curve.  
7. At fault detection important thing is graph display and interpret. First, try to find fault with compare. In a
short time you will learn difference between good and faulty or suspect circuit board. The equivalent circuit
and values are auxiliary elements. If you always look equivalent circuit and values, it can take more times
to detect fault. This product interprets VI graph. The computer program composes equivalent circuit
diagram and shows values of components by interpreting graph.
Note: Each product has different calibration settings, so that please do not lost program CD.
CONNECT PROBES: Probes can be connected each socket. Yellow ring probe is always Channel 1; Blue
ring probe is always Channel 2. Crocodile probe is always COM. USB cable for using communications
between PC and FADOS7F1.
