Q: What is the electrical parameter?
A: Around Ohm's law: U=I×R and W=U×I=U2÷R Five major parameters in the formula: voltage U, current I, resistance R, power W, frequency F, electrical parameters generally refer to these five parameters, If there is less frequency in the DC signal, there are only four parameters: voltage U, current I, resistance R and power W.
Q: What is the constant current parameter meter?
A: The constant electric parameter meter, as its name implies, is an instrument that constantly gives the above parameters, and the corresponding value is measured accordingly. For example, a constant potential is given, and the current, resistance or power flowing through the DUT is measured; the core value is The "constant" source, in particular, gives a small micro-constant signal that is less than uV or nA.
The constant electric parameter meter is a unique instrument unique to marine instruments. It is derived from the concept integration of potentiostat and galvanostat. That is, one instrument has two functions: a constant current meter potentiostat.
Traditionally, constant current potentiostats are mainly used in instrument process dynamics, electrical analysis, electrolysis, electroplating, metal phase analysis, metal corrosion rate measurement and various corrosion and corrosion research and electrochemical protection parameter testing instruments.
Q: What is the difference between a constant current meter/potentiostat and a regulated steady current power supply?
A: Generally speaking, the galvanometer is constant in current and voltage. The potentiostat is constant in voltage and current is changed. The regulated steady current power supply is automatically converted between constant current and constant voltage according to the set value.
