器校正操作方法。1. A water quality measurement signal is converted into a measurement value by a sequencer and displayed on a graphic operation panel. The graphic operation panel switches the screen to input numerical values to be used inside the sequencer and perform various maintenance processes. This is a method for correcting the measuring instrument of the water distribution monitor that enables the operation of the water distribution monitor, and the key means for switching the trend graph screen to the measured value of the measuring instrument to be calibrated is provided on the calibration screen to display the screen when necessary. A key means for returning to the calibration screen is provided on the screen to return to the calibration screen when necessary. In the graph displayed on the trend graph screen, the horizontal axis is time, the vertical axis is the measurement value, and the measurement range on the vertical axis is zero. When calibrating the span, calibrate beyond the zero and span values so that the values can be checked near the zero point and span value, and check the scale on the trend graph screen to make a measurement. Water distribution monitoring instrument calibration operation method is characterized in that so as to be without a calibration operation of the vessel.
