Measurement of High Impedance Components
Appx. 2 Measurement of High Impedance Components
The measured value obtained when testing a high impedance element (such as, for example, a
resistor with resistance higher than 100 k
Ω
) is sometimes unreliable, because such an element is
vulnerable to the effects of external interference and the like. In this case, reliable testing can be
performed by the use of guarding, that is, connecting a metallic plate to the GUARD terminal and
carrying out the measurement on the metallic plate.
Metal plate
Resin film
When measuring components on a metal plate, use, for example, resin film as insulation to ensure
terminals and the like are not short-circuited.
Open circuit compensation is high impedance measurement, so be sure to use the shielding process. If it is
not used, the compensation values may become unstable and affect the measurement values.
