Such an analog dot recorder 100 allows the measurer to judge the combination of multiple scales written on the scale plate, measurement channel numbers, and ranges when measuring multiple different ranges. and read the measured value.

(Problems to be Solved by the Invention) However, in this reading by the measurer, the measured value may be read on a scale in a different range due to a misunderstanding by the measurer. Further, when reading the measured values, the positional relationship between the line written on the scale plate and the pointer is read numerically, so there is a possibility that a reading error may occur depending on the person reading the measured value. Furthermore, since there is no indication of the timing of reading, there is a drawback that the screen lacks reliability.

In view of the above points, the present invention effectively solves the problems of the prior art, prevents misreading of the measurement range, ensures reliable reading of the measurement 11a, improves the reading accuracy, and facilitates handling. The purpose is to provide a highly reliable digital display device for recorders.

(Means for Solving the Problems) In order to achieve such an object, the present invention provides a measured value digital display unit that converts a measured value calculated in an analog method into f digital values and displays it digitally, and an input It is characterized by comprising a measurement channel display unit that digitizes the changeover switch signal and displays the measurement channel, a measurement range display unit that displays the digital output of the range setting unit, and an illumination lamp that blinks to indicate when to read the measurement value. shall be.
