    CSK05TN Schematic Diagram:
    Note:
        CMOD capacitor requirements: NPO/COG capacitor, 10% accuracy at least.
        CMOD capacitor range is 1nF-5.6nF.1nF is selected in most cases. Optimum value depends on the capacitor to be measured.
        CMOD filter capacitor must be placed as close to corresponding pin as possible, keep line as short as possible.
