DTS1 dielectric test sample box

The DTS1 dielectric test sample box is an accessory to SPECTANO 100 for
demonstrating and testing the functionality of SPECTANO 100 without a sample
test cell. The DTS1 is a demo box containing two samples: a high-precision,
low-loss 1 nF capacitor and a RC circuit simulating a dielectric sample with
losses. The main application areas of the DTS1 are in training and
demonstration purposes but it can also be used for detecting errors in a cable
setup.

DSH 100 Dielectric Sample Box

OMICRON Lab's DSH 100 Dielectric Sample Holder is designed for the
analysis of solid dielectric materials like nano-composites, polymers,
epoxy, insulation paper, glasses, thin films and other materials for
temperatures up to +200°C and voltages up to 200V(AC or DC).
Together with the Dielectric Material Analyzer SPECTANO 100, the DSH
100 is suitable to determine all important dielectric parameters such as
the relative permittivity (εr', εr''), losses (tanδ), capacitance, specific
conductivity or impedance and meets the requirements of international
standards for dielectric material analysis (ASTM D150, IEC 62631-2-1
and 62631-3-1:2017).
The DSH 100 can be used in conjunction with other impedance
analyzers or LCR meters such as the Bode 100.
The sample holder features a parallel plate electrode configuration with
guard ring. The exchangeable electrode design allows to analyze curing
processes of materials such as epoxy.

Frequency domain spectroscopy (FDS)

By using the frequency domain spectroscopy (FDS), the dielectric properties of
the solid or liquid material under test are measured by frequency sweep (5 µHz
to 5 kHz). The FDS allows fast measurements at high frequencies but requires
long measurement times at lower frequencies.
5.6

Polarization current method (PDC)

In the polarization current (PDC) method, a DC voltage is applied to the device
under test for a specific time and the polarization current is measured. From the
polarization current, the dielectric response is evaluated and the dielectric
frequency characteristic is calculated using Fourier transformation. The PDC
method is faster than the FDS at very low frequencies, but the upper frequency
is limited due to the finite rise time of the DC pulse. The test frequency range for
the PDC method is 20 µHz to 100 mHz.
