Caution
Before you measure a capacitor, be sure the capacitor is fully discharged.
Internal input circuit of the 4263B is protected when a charged capacitor
is connected. However the protection is not perfect, that is, the maximum
capacitor voltage is limited (see Figure 8-2). A capacitor is charged for a
insertion resistance measurement that is usually performed before C and ESR
measurements. If the capacitor is not fully discharged after the insertion
