Compensation and Measurement: Short compensation is recommended in
combination with the cable length compensation before measurement. First,
set the instrument's cable length compensation function to 1 m. Then, short
compensation is performed by using the furnished shorting plate. Open com-
pensation is not performed, but its values are used in the dielectric constant
equation as shown below:

α: : Correction coefficient

r
: Relative dielectric constant
Cp : Liquid capacitance (measurement data)
Co : Air capacitance (measurement data) or open compensation data
Rp: Equivalent parallel resistance (measurement data)
ω: Angular frequency (ω=2πf)
The following figures below show how compensation and measurement is
performed.
Note: the 16452A is not capable of measuring salt or ionic solutions or other
liquids with bulk conductivity due to the electrode polarization phenomenon.
Agilent is not responsible for any damage (e.g., corrosion, smear) to the
16452A caused by the reaction between the liquid under test and the
16452A.
