Abstract: A test device is provided. The test device includes test components, power supplies, an alternating current (AC) power detection circuit and an alert module. The power supplies convert an AC power through a first wire, a second wire and an earth wire to a direct current (DC) power and supply the DC power to the test components. The AC power detection circuit receives the AC power through the first wire, the second wire and the earth wire to determine whether both of voltage differences between the first wire and the earth wire and between the second wire and the earth wire is outside of respective predetermined ranges. When both of the voltage differences are outside of the corresponding predetermined range, the AC power detection circuit controls the alert module to generate an alerting signal.

Abstract: The twice scaled waveform display apparatus combines a twice scaled factor indication with the autoscaled waveform display so that an input data quality indication is produced based on factors such as signal strength, wherein the twice scaled factor is used to modulate the size of the display that is presented to the user. Thus, the generated waveform occupies a predetermined portion of the display when the signal strength and/or other input data qualities are at an acceptable level. The size of the waveform presented to the user on the display is reduced in magnitude when there is a degradation in the input signal magnitude or other quality factors.

Abstract: A pointer illuminating structure in a measuring instrument. A pointer of the measuring instrument is of a generally elongated structure and transparent. At an intermediate portion thereof, a light inducing section is provided to extend substantially perpendicularly to the generally elongated structure to form a T shape. The pointer has a flat upper surface and lower surfaces extending from about both side of the light inducing section. A reflective material is applied to the lower surfaces. Beneath the upper surface and above levels of the lower surface, cavities laterally extend to open sideways. Said cavities are defined by reflective surfaces. In alternative form, said elongated pointer is formed with a truncated conical portion at the light inducing section. Said truncated conical portion has a truncated conical reflective surface. The reflective material is applied to the side surfaces instead of the lower surface thereof.

Abstract: Adjustment of an electrical measuring instrument of the D'Arsonval type is achieved by rotation of an annular leaf spring contact mounted to rotate between an annular plate and a flanged eyelet extending through the plate and leaf spring. A conducting coil spring attached to the spring contact transmits rotary orientation of the spring contact to an armature assembly disposed for rotation against the return force of the coil spring in an magnetic field.

Abstract: An indicating instrument for use in radio or television receivers has one or two elongated prisms with an exposed surface, a mirrored surface and a further surface which is adjacent to the straight terminal of a pointer pivotable by a moving-coil instrument. The pivot axis of the pointer is parallel to the terminal and to the further surface of the prism. One or more scales are positioned in the housing of the indicating instrument in such a way that they are either directly observable by looking at the exposed surface of the prism or that the mirrored surface reflects their images toward the exposed surface, together with the image of the terminal which appears as a straight band and moves sideways in response to pivoting of the pointer.
