If it is determined that the measurement value has a repeating cycle, the MCU 140 determines whether the measurement value has a repeating cycle. The predicted value of the measured value according to can be controlled to be displayed through the display unit 160, especially the graph display unit 163. Here, the repeated cycles do not necessarily have to match, and can include similar things within a given range. Similarity can be determined by various methods of determining similarity, including setting the maximum deviation limit of the measured value at each time interval and the deviation of one cycle, and known algorithms such as machine learning can be used as needed.

When the failure diagnosis mode is selected by the fourth operation unit 190, the MCU 140 determines that the measurement value input from the measuring device is discontinuous a set number of times within a set time or is interrupted for a set time, The fault can be controlled to be displayed through the display unit 160.

When the alarm setting mode is selected by the fourth operation unit 190, the MCU 140 sets a setting value requiring output of an alarm sound by the third operation unit 180, and the measured value of the measuring device is set. When the value is reached, an alarm sound can be output through the alarm buzzer 230. Accordingly, the user can easily recognize through an alarm sound whether the measured value of the measuring device has reached the set value by registering the desired set value in advance by manipulating the third operation unit 180.

When the automatic recognition mode is selected by the fourth operation unit 190, the MCU 140 determines the type of the measuring device by matching the signal pattern for the measurement value of the measuring device with the signal pattern for each measuring device stored in the memory unit 130.

Here, the format may be a generally used method for the measurement medium, including the range of the measurement value and the method of processing decimal points. In addition, known machine learning algorithms can be used to match signal patterns. Since the MCU 150 can only be applied when the signal pattern of the measuring device has discriminability, this can be applied to measuring devices whose signal patterns cannot be identified. It may be configured to notify the outside through the display unit 160.
