    摘要: An instrument for measuring laser energy in the visible range and which determines when the optical energy exceeds the accessible emission limit for a Class I laser. The instrument employs a photoelectric detector and a filter for a range of 476 to 633 nm. The instrument measures the optical energy as a function of time and compares the measured value with the accessible emission limit for a Class I laser at various critical points in time. A 3-digit engineering-notation display format is used to output the computed time at which the laser energy exceeds the Class I limit, as well as the total energy measured in 10 seconds. The instrument is adapted to measure either CW laser radiation, pulsed laser radiation, or each pulse of laser radiation, computes and applies a correction factor for optical error conditions or variations between optical detectors, and measures and compensates for background energy. Mode and scale information, and sensed data, are read into a micro computer and are read out on a LCD display.

    摘要: A line voltage monitor which can measure d.c. and RMS a.c. voltage and frequency, maximum and minimum RMS voltage, which displays input voltage, and computes and displays % regulation from the measured maximum and minimum voltage values. Analog input circuitry attenuates and squares the input voltage. A voltage-to-frequency converter produces logic pulses at a rate proportional to the squared signal. A 16-bit counter integrates V.sup.2 by accumulating pulses from the voltage-to-frequency converter. A second 16-bit counter increments at a 1 MHz rate to determine the cycle period T of the input. A microcomputer divides the .intg.V.sup.2 value by the period T and then takes the square root, yielding the RMS value of the input voltage. The microcomputer can be switched to determine the % regulation and the input frequency, and can be used to enable display of V.sub.max, V.sub.RMS (t) or V.sub.min, as well as the regulation.

    摘要: A readout device connected to a parent metering system contains a digital display for circumventing the non-linearity of analog meter movement in the parent system. The readout device displays both numerical and dimensional information in a clear, legible form with both probe and range scale factors accounted for in the display itself. A "probe" switch on the front panel of the module encodes the logarithm of the scale factor associated with the probe in use to a two's complement binary number, and the full scale range information from the "range" switch is encoded in the same manner. This information, along with function information from the "function" switch, is processed by a scale computation circuit which positions the decimal point and causes the units of measurement to be indicated accordingly.

    摘要: An apparatus for measuring and displaying the sag and surge voltage values of an AC power supply. Two inputs are attenuated, filtered and the peak difference is converted to a binary number by an analog-to-digital (A/D) converter. A digital comparator compares these conversions with the values stored in a maximum and minimum register. If the output of the A/D is larger than the contents of the maximum register, the previous maximum register's contents are replaced by the A/D output. If the output of the A/D is smaller than the contents of the minimum register, the previous minimum register's contents are replaced by the A/D output. Dual light emitting diode displays provide a numerical readout of the contents of the maximum and minimum registers.
