Strictly controlling water environment parameters—from farming to preliminary processing—is not only a technical requirement to overcome technical barriers to trade (TBT) and sanitary and phytosanitary (SPS) measures, but also the key to protecting corporate reputation.

This article addresses various questions in turn, covering whether conversion is permitted, how to establish the K-factor, when the factor ceases to be valid, and which equipment is suitable

Output impedance testing connects a J2111A current injector and probe to an LM117 output; small-signal load steps use an AWG and no injector bias current.

A 2-port shunt-through setup with the Bode 100 uses Gain/Phase mode, a 50 Ohm termination on Ch2, Thru calibration, and a logarithmic sweep to read impedance and estimate inductance.
