    CALIBRATION ALIBRATION Overview Calibration (trimming) eliminates stray Background capacitance and series impedance from the testing fixture. It is required when using the instrument in a new environment, or using a new set of testing fixtures. The testing fixture clips are separated by a distance O/C trimming equal to the normal testing position.
