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
case connection A large area of metal can add noise to the
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.
