Notes Model 400H has a 5" indicating meter with mirror scale and measures voltages from 0.1 mv to 300 volts. The high input resistance of 10 megohms effectively minimizes loading to circuits under test. A highly stabilized amplifier with 56 db feedback provides exceptional long term stability; even line voltage changes of *lo% cause negligible variations. Readings are direct in volts or db. Operation is extremely simple; input voltages up to 600 volts peak will not damage the instrument. The instrument is of highest quality construction throughout, and is available either in the lightweight, rugged -hp- portable cabinet or for rack mounting.
