PURPOSE:To make it possible to achieve a multi-function indication by using a simple indicating device, when a measured value is outside of the range of upper limit and lower limit of set values, by indicating the alarming condition and the upper and lower limit values on a monocolor analog indicating device by light or shade. CONSTITUTION:When upper limit and lower limit set values range from 30 to 70 and a measured value is within this range, a piece of indicating element corresponding to the measured value continuously radiate light to make a light indication (A). In case when the measured value is exceeding the upper limit of set value, a signal whereby pieces of luminous element from zero to the measured value are made to radiate and a signal whereby pieces of luminous element within the upper limit and lower limit set values are made to radiate are emitted alternately, and those pieces being within the two set values make continuous radiation to be indicated strongly, and pieces of indicating element for other measured values make intermittent radiation to be weakly indicated (B). In case if the measured value is below the lower limit set value, pieces of luminous element from zero to the measured value and those within the set values make intermittent radiation to be indicated weakly as (C). |
