<p><P>PROBLEM TO BE SOLVED: To shift to a prescribed calibration mode by a simple key operation in a small number of key switches. <P>SOLUTION: An indicator includes a "FUNC" key for shifting from a measurement state (calibration lock release) M10a to a calibration setting mode M40 for setting a plurality of calibration values, and a "ZERO/←" key and a "SPAN/←" key for setting the calibration value in the calibration setting mode M40. Also, the indicator shifts to a ZERO calibration mode M20 by long depression of the "ZERO/←" key in the measurement state (calibration lock release) M10a, and shifts to a SPAN calibration mode M30 by long depression of the " SPAN/←" key. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
