3 Operation
Introduction
This chapter describes how to measure the dielectric constant () of the liquid
using the 16452A.
• The standard measurement sequence is shown in this chapter.
• Some instructions for the temperature measurement are provided at the
back of the chapter.
Measurement Sequence
Relative permittivity (
r
) can be calculated from the ratio of the capacitance of
a material to that of air (nearly equal to that of a vacuum). The standard
measurement sequence is as follows:
1. Prepare the test fixture for use.
2. Connect the test fixture.
3. Check the SHORT residual.
4. Set the instrument for capacitance measurement.
5. Do a SHORT compensation.
6. Do the air capacitance (C
o
) measurement.
7. Do the liquid capacitance and resistance (C
p
, R
p
) measurement.
8. Drain the liquid (after measurement)
9. Do the data processing- Calculate dielectric parameter from measurement
data.
