Knight RC-100- Resistance-Capacitance Bridge 1944

10pF up to 5000µF    0.5Ω up to 500MΩ    antiquated

Resistance-Capacitance Bridge are most commonly used as a capacitor tester. The balanced bridge measures capacitance from 10pF up to 5000µF and resistance from 0.5Ω up to 500MΩ. During component value testing, the magic eye tube serves as the null-indicator. When the bridge is far from balanced, the target area of the magic eye tube glows completely closed green, and in fact overlaps. As the pointer dial approaches balance point, first the overlapping disappears and eventually the entire target area of the eye tube is completely open (dark). The bridge is balanced when the maximum dark area is indicated, and you can then read the value of your component on the faceplate scale. The magic eye tube is used for both Leakage testing and component value testing.

Precision, non-aging resistors insure lasting accuracy. All units are calibrated at 77°F. AC ranges are calibrated on a 60 cycle sine wave. In choosing ranges always endeavor to have the readings fall in the upper (or right hand) half of the scale for greatest accuracy. RANGES The following ranges are self contained in your 630-PL: DC Volts 2.5-10-50-250-1000-5000 at 20,000 Ohms per Volt. AC Volts 0-3-10-50-250-1000-5000 at 5,000 Ohms per Volt.

WESTON MODEL 80 ANALYZER (MULTIMETER) were built in the 1950s and called analyzers at that time. Now they are known as multimeters. The D'Arsonval/Weston meter is positioned vertically instead of laying flat horizontally to exemplify their design. Weston created the D'Arsonval movement which used a fine metal spring to give proportional measurement and a built-in permanent field magnets made deflection independent of the position of the meter. These features enabled dispensing with wheatstone bridges, and made measurement quick and easy. By adding a series or shunt resistor, more than one range of voltage or current could be measured with one movement.
