Abstract: A four-wire ohmmeter connector includes a pair of elongated members spaced apart from each other by an interconnecting web. A pair of elongated contacts are mounted on forwardly projecting portions of each of the elongated members. An insulative housing surrounds the elongated members, contacts and web. The contacts mounted on one of the elongated members are connected through separate wires to a positive probe, and the contacts mounted on the other of the elongated members are connected through separate wires to a negative probe. The elongated members are inserted into respective terminal apertures of a four-wire ohmmeter. A pair of semi-cylindrical conductive sleeves are aligned with each of the apertures, and they make contact with and compress the respective contacts that are inserted into the aperture.

Abstract: A resistance measuring circuit includes a current generating component, a current control component, and a voltage measurement component. The magnitude of a target resistance can be measured by connecting the target resistance between first and second measurement terminals of the resistance measuring circuit, applying a current generated by the current generating component to the target resistance, and determining the voltage across the target resistance. When no target resistance is connected between the first and second measurement terminals, the current control component controls the current generating component to reduce current consumption of the resistance measuring circuit.

The matrix switch connects the output pins to either the digital multi-meter or the time domain reflectometer perform the respective tests. Corresponding to the output pins, the matrix switch has a plurality of input/output channels, such that wire paths can be established between the output pins. The time domain reflectometry and characteristic tests can thus be performed on each line of a cable to be tested, and each wire path established between the output pins or the lines.

Abstract: A low error, switchable measurement lead detect circuit (9) for providing accurate current measurement readings and reducing susceptibility to false measurement lead detections due to leakage current is described. A gate (14) that receives an input select voltage Vs selectively connects either a supply voltage, Vd, or ground to the input of a voltage divider (13). Vd is connected during a measurement lead detection mode of operation or open fuse detection mode of operation, and a ground is connected during a current measurement mode of operation. During the measurement lead detection mode of operation, if the pin of a measurement lead is present in a split jack (12), the voltage divider (13) divides the supply voltage, Vd. Conversely, if no measurement lead pin is present in the split jack (12), the output voltage, Vo, of voltage divider (13) equals the level of Vd. During open fuse detection mode of operation, a measurement lead is present in the split jack (12), and if a fuse (F1) is present, the voltage divider divides the supply voltage, Vd. If a fuse (F1) is not present or is blown, the output voltage, Vo, of voltage divider (13) equals the level of Vd. During the current measurement mode of operation, the voltage divider (13) and shunt (11) form a series parallel circuit when a measurement lead pin is located in the split jack (12). The impedance of the shunt (11) is negligible in comparison to the impedance of the voltage divider (13), and the voltage drop across shunt (11) is proportional to the injected current. Because the voltage divider (13) is grounded through the gate (14) during the current measurement mode of operation, no error current from supply voltage, Vd, passes through the shunt (11). As a result, the accuracy of current measurement readings made during the current measurement mode of operation is improved. Because the supply voltage does not produce an error current during the measurement mode of operation, the overall impedance of the voltage divider (13) can be reduced to reduce susceptibility to leakage current during the measurement lead detection mode of operation.

Abstract: A tester for power transformers and capacitors includes a pulse generator for applying a pulsating test signal to a pair of test leads which may be connected across the terminals of the device to be tested. Also connected across the test leads are a capacitor detector, an inductor detector and a continuity detector. If the connections to the transformer or capacitor in the device to be tested are good, the capacitor detector and inductor detector will distinguish one from the other and indicate that its condition is good. If the connections to the device are not good, the continuity detector will indicate whether there is a short circuit or open circuit condition. The detectors are coupled through control logic circuitry to an indicator circuit including a horn and blinking lights for providing unique indications of capacitor okay, inductor okay, short and open conditions. The capacitor detector provides a discharge path for a capacitor and detects the discharge current flow. The inductor detector responds to the kickback voltage of an inductor, which is of a polarity opposite to that of the input test pulse. The continuity detector measures voltage level to distinguish between impedance levels respectively corresponding to substantially open and substantially short circuit conditions.

Abstract: A multimeter is provided having an erroneous input prevention mechanism that allows more than one mode to be assigned to an input terminal hole located in a central section of a shutter board based on movement of a rotary switch. When the rotary switch is rotated, the first and the second drive-side protrusions formed at separate locations from the selector push away the first or second slave-side protrusions in the slave shell to rotate the shutter board about the center at the negative common terminal hole. Thus, only a specific terminal hole is in the open state. Even when the rotary switch is rotated to a predetermined position, the shutter board does not rotate to leaving the first input terminal hole in the open state.
