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.

The 3A6 Amplifier is a general-purpose, dual-trace plug-in unit designed for use in the Types 561B, 564B and 565 Oscilloscopes. The Type 3A6 features two separate channels with identical characteristics. It can be operated in any one of five modes for a variety of single and dual-trace displays. Two Type 3A6's can be used for X-Y curve tracing, but without synchronized switching or channel pairing. BANDWIDTH DC to 10Hz at 3dB down. AC-coupled low-frequency response is 2Hz, 0.2Hz with 10X probe. RISETIME Approximately 35ns. DEFLECTION FACTOR 10mV/div to 10V/div in 10 calibrated steps, 1-2-5 sequence; accurate within 3%. Uncalibrated, continuously variable between steps and to approximately 25V/div. INPUT RC 1 megohm paralleled by approximately 47 pf. MAXIMUM INPUT VOLTAGE 600V combined DC + peak AC. OPERATING MODES Channel 1 only (polarity of Channel 1 can be changed to provide 180° inversion); Channel 2 only; Alternate -- Channel 1 and 2 switched electronically on alternate sweeps; Chopped -- successive 4µs (approx) segments of each channel are displayed at an approx. 135KHz rate per channel (chopped transient blanking is provided); Added -- outputs of CHannel 1 and 2 added algebraically. INTERNAL TRIGGER SIGNAL Selectable from the output of Channel 1 only or from the combined output of the unit. Triggering from Channel 1 only permits viewing the true relationship between two signals when operating the unit in either alternate or chopped mode.10 MHz .5us/div to 1s / div in 20 Steps antiquated

(description below copied directly from manual July 1959) ACCURACY Your 630-PL is accurate to within 3% of full scale reading on all DC ranges except the 5000 volt range which is within 5%, 4% on all AC ranges except 5000 volts which is 5%, and 3% of the scale length on all resistance ranges. 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. DC Microaxnperes 0-100 at 250 Mv. DC Milliamperes 0-10-100-1000 ot 250 Mv. DC Amperes 0-10 at 250 Mv. Ohms 0-1000-10,000 (4.4-44 at center scale). Megohms 0-1-100. . (4400-440,000 at center scale). Output Volts(AC) 0-3-10-50-250-1000 at 5,000 Ohms per Volt. Decibels -20 to +11, 21, 35, 49, 61, 75 on 600 Ohm line. Your 630-PL is well constructed but like any instrument should be handled carefully. You will also want to keep the panel clean as cleanliness and carefulness go hand in hand.
