The papers [8, 9] provide a detailed analysis of the most commonly used portable devices, including: Polish WG-407, WG-507 and MRU-200, Japanese PET-7, ZED-meter of the US, Ukrainian IK-1U and Russian impedance meter
"The Bode 100 is not only a state-of-the-art vector network analyzer--it also works as a frequency response analyzer, impedance meter
, gain and phase meter, and sine-wave generator."
The Basic Parameters of the Characteristic Impedance Meter
Skin impedance was then determined using an impedance meter
(Asahi Techno Lab., Ltd., Kanagawa, Japan) 1 h after hydration.
Bruel & Kjaer's Impedance Meter
System provides aerospace engineers with a user-friendly system, suitable for carrying out research and production quality control impedance measurements, up to 150 dB SPL on engine nacelle liners.
To compensate for these errors, two other related electrical parameters, phase angle ([theta]) and impedance (Z), were also measured at these two frequencies using the CI meter (CI meter is Chari's impedance meter
designed and constructed by the corresponding author).
In his office, he uses a bioelectrical impedance meter
to measure skeletal muscle versus fat tissue mass, from which calculations can be made for the number of calories per day required to reduce weight in a certain period of time.
Such equipment includes a lab-quality digital RCL bridge, vector impedance meter
, network analyzer, etc.
Also, an AC impedance meter
can be affected by high-frequency noise.
