Eddy Current Testing with MFLI Lock-In Amplifier

on 05.08.2015 at 12:07 by Marco Brunner on Blog of Marco Brunner
This blog describes a method to detect material defects. Eddy current measurements are used for non-destructive material testing (NDT). An alternating magnetic field is penetrating a sample. The material defect is detected by a phase shift. In the first part […]

Using HF2IS Impedance Spectroscope as a DC Impedance Meter

on 18.11.2014 at 11:11 by James Wei on Blog of James Wei
Up until now, the blogs related to impedance measurement are mostly related to how to setup a measurement and optimize the ac frequency sweeps. As a matter of fact, the HF2IS Impedance Spectroscope can also be used as a dc […]

Demodulating down to DC with HF2LI

on 18.11.2014 at 09:52 by Jelena on Blog of Jelena Trbovic
Many of our customers use the possibility to measure DC voltage and current, together with an ac signal by setting the demodulation frequency ω=0. The measured value is seemingly incorrect as you need to divide the obtained rms value with […]
