3 terms and definitions
The following terms and definitions apply to this document.
3.1 Surface resistance
The ratio of the voltage applied between the two electrodes on one surface of the test material and the current flowing through the surface of the sample at the specified electrochemical time,
The current is mainly the current flowing through the surface of the sample, but also part of the flow through the sample volume of current components. Between the two electrodes may be formed
Polarization is negligible. Unless otherwise specified, the surface resistance is measured after 1 minute of electrochemical.
4 principle
Direct measurement with high resistance meter. Measuring the surface resistance diagram shown in Figure 1.
Description.
1 --- DC current E;
2 --- test voltage U (V);
3 --- Output resistance on voltage U0 (V);
4 --- the surface resistance of the test object Rx (ohm);
5 --- Output resistance R0 (ohm);
6 --- DC amplifier;
7 --- analog-to-digital converter.
