  • Page 11: Introduction

    Introduction SPECTANO 100 SPECTANO 100, in conjunction with its accessories or as stand-alone unit, is a test system for dielectric analysis of solid and liquid materials. It combines the time-domain and frequency-domain analysis within a wide frequency range from 20 μHz up to 5 kHz in one device and provides an output voltage range from 100 mV to 200 V .

  • Page 12: Dts1 Dielectric Test Sample Box

    The DTS1 dielectric test sample box is an accessory 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.
