These instruments are millivokmeters and voltmeters with mean value indicating devices that offer offective value calibration, and are used for measuring sine wave alternating current voltages of ΙΟΟμν — 300V [150V — 500V] in the 5Hz — 1MHz frequency range. These instruments are highly sensitive and precise. New circuitry insures wide range readings with excellent linearity characteristics. The use of output terminals enables application of these units as wide-band high gain a ...
