<P>PROBLEM TO BE SOLVED: To reduce the labor of an operator who calibrates a signal converter. <P>SOLUTION: The current generation device for calibration of a signal converter which converts a signal current value within a predetermined range into another signal value includes: an operation part including a first function operator, a second function operator, a third function operator and an adjustment mode transition operator; and a current control part for setting a signal current value to be transmitted to a signal converter as the object of calibration within a predetermined range. When accepting the operation of the adjustment mode transition operator, the current control part switches, by operating the third function operator, between a step mode for increasing/decreasing the signal current value with a predetermined width on the basis of the first function operator and the second function operator and a span mode for switching the signal current value between the upper limit value and lower limit value of the predetermined range on the basis of the operations of the first function operator and the second function operator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
