A measurement technique which is used to calibrate current coils for calibration of power clamp meters in AC current range from 5 to 1000 A has been developed.
Normative IOTN AC and DHC were recorded according to the calibration criteria.
For this purpose unique experimental apparatus created by the combination of original calibration-free measuring system designed for ac magnetization loss measurement and non-magnetic vacuum vessel with two-stage cryocooler for sample cooling was used.
The calibration signal is fed into the WPT-Pre (AC) through the specific resistance as the output impedance (K) of the calibration signal.
Here, we describe the detailed calibration of the electric field sensor with the WPT-Pre (AC) using the onboard calibration system.
To obtain max(n/ N), we measured max(n) from the spatiotemporal data and N from separate calibration experiments (see the section entitled " Measurement of ITP-AC Parameters" in this work).
"Onboard calibration system" section describes the equivalent circuit, which considers the coupling of the WPT-Pre (AC) input and the WPT-S.
For each spectrometer, the calibration equations were developed for melting rate (MR) and for dry matter (DM), ash content (AC), lipid content (Lip) and protein content (Prot) as reported by Bastianelli et al.[ 30].
And there was calibration.
