Resistor Rn and spectral noise resistance Rsn(f).
       2 real-time storage
      CS Studio stores measurement data in real time, and even if the test is interrupted due to power failure, the data before the interruption is automatically saved.
       3 timing measurement
       The CS Studio test software has a timing measurement function. For some characteristics that need to be studied over time, the test parameters and interval time can be set in advance, so that the instrument can automatically measure at an unattended time, which is convenient for experiments.
Technical advantages
       1 AC impedance
       The instrument adopts correlation integral algorithm and dual-channel synchronous oversampling technology, which has strong anti-interference ability, especially suitable for AC impedance measurement of high-resistance system (>109Ω) such as coating and concrete, and also for Mott-Schottky curve and differential. Capacitance curve is drawn. The software can display the open circuit potential in real time, and the user can output an accurate polarization overpot without input.
       2 polarization curve
       With linear polarization and Tafel polarization curve measurement function, the user can set the anode retrace current of the cyclic polarization curve (passivation film breakdown current) to determine the pitting potential and protection potential of the material, and evaluate the intergranular corrosion sensitivity. Sex. The software uses a nonlinear fitting algorithm to resolve the polarization curve, which can be used for rapid evaluation of material corrosion resistance and corrosion inhibitor performance.

4 Electrochemical noise
        The high-resistance follower and zero-resistance ammeter are used to measure the spontaneous potential and current fluctuation of the corrosion system, which can be used for local corrosion research such as pitting, galvanic corrosion, crevice corrosion and stress corrosion cracking. Through noise spectrum analysis, the induction, growth and death processes of metastable pits or cracks can be evaluated. Based on noise resistance and pitting index calculations, it can also be used for local corrosion monitoring.
