Direct-reading impedance meter that compares current flowing through calibrated resistor with current through unknown impedance is described; vector sum of these 2 currents is displayed on calibrated meter to determine phase angle; instrument uses modified Gruetzmacher bridge which eliminates null-adjustment problems.
