Operator Manual

NOTE

The electrometer circuitry in the preamplifier is highly sensitive to moisture and physical damage. Use extreme care when the preamplifier case is opened as the high impedance electrometer circuitry is easily damaged. Do not leave the preamplifier enclosure in the open position for any extended period of time.

The preamplifier terminations are listed below.
