MEASUREMENT VALUE DISPLAY DEVICE

PROBLEM TO BE SOLVED: To display a standard display scale, an upper limit alarm display scale, and a lower limit alarm display scale without enlarging a device. SOLUTION: A standard display bar 130, an upper limit alarm display bar 140, and a lower limit alarm display bar 150 are flashed in the display part of a bar display part 100 for displaying a measurement value. The scale value, upper limit alarm value, and lower limit alarm value can be set by reading and setting the value of measured current, voltage, power or the like as a standard value, deriving and setting the upper limit alarm value and the lower limit alarm value according to the magnitude of the standard value, or deriving and setting the standard value, upper limit alarm value and lower limit alarm value according to the magnitude of a set maximum scale value. According to such a structure, the display part can be miniaturized to miniaturize the device. The standard value, upper limit alarm value, and the lower limit alarm value can be automatically derived and set.
