Title: Method and apparatus for testing precision impedance elements
IPC: G01R17/00
Filed: 1957-09-10
Abstract: 871,618. Measuring bridges. REEVES INSTRUMENT CORPORATION. Sept. 10, 1957 [Dec. 31, 1956], No. 28582/57. Class 37. An impedance is tested by inserting it in one arm of a Wheatstone bridge, the other arms of which comprise a pair of tapped ratio arms and a standard impedance, respectively, and then comparing the out-of-balance voltage which will exist if the impedance to be measured is either above or below the value of the standard impedance with two reference voltages, the bridge being balanced if the unknown impedance is exactly equal to the standard impedance. In the embodiment shown in Fig. 2 the insulated segments 42, 43, 44 of a selector switch 38 with a motor-driven arm 39 are connected to tapping-points 19, 14 on ratio arms 11, 10 and junction-point 25, respectively, the resistive portions 16, 17 of arm 10, 11 being such that the voltages (forming the reference voltages) across them is equal in magnitude to the voltages that would appear between 25 and ground when the ohmic resistance of unknown resistor Rx is exactly equal to its lower and upper tolerance limit respectively. Segments 45, 46, 47 are connected to earth and arm 39 and point 20 are connected to terminals 49, 48, respectively, and these are connected to an amplifier 50 and cathode-ray oscilloscope 51. Fig. 3a shows the oscilloscope waveform as the arm 39 is rotated once from segment 42 in the anti-clockwise direction, the voltage shown during interval a-b being: that across resistive portion 17, during time interval b-c zero (segment 47 earthed), during time interval c-d that corresponding to the deviation of Rx from its nominal value R8 during time interval e-d zero (segment 46, earthed), during time interval e-f that corresponding to voltage across resistive portion 16, and during interval f-a zero again (segment 45 earthed). The error in Rx can therefore be directly compared with the tolerance limits (in Fig. 3a the error is actually within both limits). In the further embodiment (Fig. 4, not shown) the selector switch is omitted and replaced by relays, a tap-selector relay and a voltage comparison relay, the two terminals of the former being connected to the two tapping-points on the ratio arms and the armature to one terminal of the latter relay, the other terminal of which is connected to the oscilloscope. The tap selector relay is energized directly from an A.C. supply which is also connected to a 90 degree phaseshifter which supplies the voltage comparison relay. It is stated that the reactance of capacitors and inductors may be tested by replacing the D.C. source 28 by an A.C. source and by coupling a phase-sensitive demodulator between amplifier 50 and oscilloscope 51, although for accuracy the reactance of the unknown and standard impedances must be high compared with their resistance. A plurality of taps, or resistors could be provided on, or as, the ratio arms 10, 11. Specification 871,619 is referred to.
