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 amplifiers or pre-amplifiers on other
1. Wide band-width of 5Hz — 1MHz.
2. High accuracy; ±2%.
3. Highly precise, reliable and stable voltmeters of new
4. Wide-use voltmeters with two decibel scales (OdB - IV. OdB ~
0.775V) in addition to the effective voltage scales.
5. The output is calibrated at lVrms full scale, so that
these instruments can be used as low~noise high-gain
pre-amplifiers on wave form monitors.
