Information
                                    The Keithley Model 604 Differential Electrometer Amplifier
is a completely solid-state instrument that can be used
by itself single-endedly or differentially either as
an amplifier or a millivoltmeter. The Amplifier has selectable
gains of 10 to 10⁴ in lx and 3.33x steps corresponding
to the VOLTS Switch settings of 1 to .001.

When used in conjunction with the Model 6041 Differential
Current Shunt the Model 604 becomes a single-ended or
differential picoammeter. Single-ended and differential
current measurements from 10⁻⁶ to 10⁻¹⁴ ampere can be
made with this setup. Also, high megohm resistors
may be installed within the Model 604 to allow shunt
picoammeter operation.
