Description: DC-Microvolt-Anmeter
                                    The Model 425A DC Microvolt-Ammeter is an
extremely sensitive measuring device which measures
voltages from 1 microvolt to 1 volt and currents from
1 picoampere to 3 milliamperes. An input resistance
of 1 megohm on all voltage ranges minimizes errors
due to circuit loading. The Model 425A can make
measurements in circuits which are off ground potential,
for the chassis and input circuit may be isolated
from the cabinet. The Model 425A provides an output
which will drive either potentiometer or galvanometer
recorders. It will deliver up to 1milliampere at 1 volt .
