摘要： A variable color digital measuring system performs sequential tests and exhibits each measured value in a color in accordance with the previous measurement errors. An error memory is provided for storing a value indicating whether there was a measurement error. A color control illuminates the present measured value in a first color when the contents of the error memory indicate that there was no previous measurement error, and in a second color when the contents of the error memory indicate that there was a previous measurement error.

摘要： A bar-graph-display data input/output system, having increased resolution, utilizes a bar graph display having a number of bar segments greater than the number of associated actuating switch devices. Selection of a given level in the increasing direction is obtained by actuating the next-higher switch; the bar graph starts at a level immediately above that bar segment adjacent to the switch next-lower than the actuated switch and slews, or moves, to each progressively higher position after a fixed time interval at each position, until either the switch is inactivated or the bar reaches the position of the switch activated. In the decreasing direction, the display bar starts at a level immediately below a bar segment directly adjacent to that switch next-higher than the switch actuated, and slews to progressively lower levels, after a similar fixed interval at each position until the activated switch is either inactivated or the bar reaches that segment directly associated with the activated switch. The bar graph, and the associated digital level output data, may be increased or decreased from a present position by actuating higher, or lower, switches.

摘要： A level indicator comprising a plurality of comparators for comparing an analog signal with a respective value of graduated reference voltages generates one or more output signals in response to the analog signal exceeding each reference voltage. A plurality of storage circuits is provided each associated with a respective comparator and with a respective one of successively arranged luminous elements. Each storage circuit is responsive to the output of the associated comparator and delivers a signal for the associated luminous element, which signal may also be used to inhibit the passage of the outputs of the other storage circuits of descending order.
