CS110 Electric Field Meter

3. CS110 Measurement Details

The charge amplifier circuitry of the reciprocating electric field meter is
depicted in Figure 2. Induced charge on the sense electrode results in the
operational amplifier placing charge on the feedback capacitor C in order to
restore the sense electrode to virtual ground.

meter

The charge amplifier output during a measurement cycle of the reciprocating
electric field meter is illustrated in Figure 3.
