PURPOSE: To selectively and digitally display a plurality of detection parameters by digitally figures showing sensor signals if the numerical value read mode is selected, and graphically displaying them if the normal mode is selected.
CONSTITUTION: Equipment 10 automatically enters the normal mode at the turning on of power, displays a parameter level graphically on an electronic gage 12, and indicates an alarming state if the level is out of a predetermined range. To access other operating modes, when a service input part 28 and a clear input part 30 are grounded simultaneously, mode numbers corresponding to the current operating modes appear on a digital display 18 in sequence, so the input part 28 is shut off and locked when the desired mode is reached. To enter the numerical value read mode during scrolling of the functional modes, when the corresponding mode signal is displayed 18, the input parts 28, 30 are shut off, scrolling us performed with the input part 30 grounded until the desired parameter number is displayed on a gear display 24, and the parameter level selected is digitally displayed 18.
