Page106 33 LCR-8000G Series User Manual Measurement tip Hi/Low impedance If the measured impedance is greater than 1kΩ, the standard four-terminal connection is not necessary. Run S/C trim to remove the effect of series lead impedance. If the measured impedance is lower than 1kΩ, four-terminal connection can reduce the effect of contact resistance at the test component. Metal component A large area of metal can add noise to the case connection measurement. Here is how to minimize the effect. If the metal is connected to one of the terminals, this should be connected to the Hforce (Yellow) terminal side. If the metal is NOT connected to either of the terminals, connect the GND clip. Small-sized capacitor When measuring small, SMD-size capacitors, run O/C trim at the measurement frequency (Spot trimming) to eliminate the residual capacitance. Make sure the measurement lead positions are fixed during trimming. Small-sized inductor When measuring small, SMD-size inductors, run S/C trim at the measurement frequency (Spot trimming). The LCR-8000G measures the difference between the inductance of S/C trimming and the inductance of test component. Four-terminal fixture set is recommended and make sure the measurement leads are fixed during trimming. 34 GETTING STARTED Wire capacitance When measuring the wire capacitance, the fixture clips that are marked with HF(High Force)/HS (High Sense) should always be connected to the point that is influenced the most by noise. Wire inductance The wire inductance should be subtracted from the measurement result.  5cm, 1mm diameter wire has 50nH inductance  5cm, 2mm diameter wire has 40nH inductance Frequency factor When an inductor is measured at a frequency in inductor much lower than that for which it is designed (for measurement example, an HF choke tested at AF), the inductor tends to behave as an inductive resistor. In these circumstances, measurement accuracy is widened by (1 + 1/Q) where Q is the quality factor. Air-cored coils Air-cored coils can pick up noise very easily, therefore they should be kept well clear of any test equipment that may contain power transformers or display scan circuitry. Also, keep the coils away from metal objects which may modify inductor characteristics. Iron-cored and ferrite inductor The effective value of iron-cored and ferrite inductors can vary widely with the magnetization and test signal level. Measure them at the AC level and frequency in use. When core materials are damaged by excessive magnetization (for example: tape heads and microphone transformers), check that the test signal is acceptable before connection. 35 LCR-8000G Series User Manual BASIC MEASUREMENT Basic measurement measures DUT in numerical style.

It is required when using the instrument in a new environment, or using a new set of testing fixtures. O/C trimming The testing fixture clips are separated by a distance equal to the normal testing position. S/C trimming The testing fixture clips are connected by a piece of wire or a component lead (but no direct connection between the clips). 123 LCR-8000G Series User Manual Alternative S/C trimming 124 An alternative method of S/C trimming.
