A calibration work support device includes a calibration target setter that sets a target value of a simulation signal input to a device in calibration of the device, a simulation signal acquirer that acquires an input value based on the simulation signal, a proper range determiner that determines whether the input value is within a proper range for the target value, a proper range notifier that notifies a user whether the input value is within the proper range, an output value acquirer that acquires an output value output from the device in accordance with the simulation signal, a condition determiner that determines whether at least one of the input value and the output value satisfies a predetermined condition, and a recorder that records the input value and the output value if at least one of the input value and the output value satisfies the predetermined condition.
