Operation Specifications Specifications Table 1-2 Function: For use with 4192A, 4194A, 4274A, 4275A, 4276A, 4277A and 4278A instruments. Permits connecting miniature leadless components to the UNKNOWN terminals (4-terminal pair configuration) of the 4192A, 4194A, 4274A, 4275A, 4276A, 4277A, or 4278A. Measurable Components: Miniature components with terminals on opposite faces (Distance between component terminals ≤ 10mm).

Operation ZERO OFFSET ADJUSTMENT ZERO OFFSET ADJUSTMENT The 16334A has inherent residual impedance and stray admittance that affects the accuracy of the measurements. To compensate for, or negate, these residuals in order to minimize measurement error, the instrument’s zero offset adjustment procedure should be performed. The zero offset adjustment procedure is described in the instrument’s manua1.
Operation OPERATION OPERATION Setup and measurement procedure is as follows: 1. Set the instrument’s cable LENGTH to 1m. 2. Connect the 16334A directly to the UNKNOUN terminals of the instrument. 3. Perform the ZERO offset adjustment described in the instrument’s operation manual. 4. Connect the DUT to the 16334A test fixture. WARNING DO NOT APPLY MORE THAN ±42V OF DC BIAS VOLTAGE TO THE UNKNOWN TERMINALS.
