Appendix2 Measurement of High Impedance Components
A3
The measured value obtained when testing a high impedance element (such as, for example, a resistor with
resistance higher than 100 k
) 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.
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.
