The setting information related to the basic functions consists of information related to whether the basic functions are enabled or disabled, parameter values related to the basic functions, and setting information related to the detailed functions. The setting information regarding the detailed function is composed of information regarding whether the detailed function is enabled or disabled and parameter values regarding the detailed function. Such a relationship is called a hierarchical relationship regarding setting information. That is, the basic functions are hierarchically higher than the detailed functions, and the detailed functions are hierarchically lower than the basic functions.

Next, the setting input screen 50 for accepting input of setting information will be described.
FIG. 5A shows an example of the setting input screen 50. As shown in FIG. As shown in FIG. 5A, the setting input screen 50 has a tab selection area 51 and a setting information input area 52 . The tab selection area 51 displays an "AMP" tab, a "DATA" tab, an "ALARM" tab, an "I/F" tab, and a "DISP" tab. When the user selects one of the tabs, the setting information associated with that tab is displayed in the setting information input area 52, and the setting information can be input. Each tab displayed in the tab selection area 51 corresponds to five basic functions of the measurement recording apparatus 1, ie, an acquisition function, a recording function, a notification function, a communication function, and a display function.
By displaying the setting information of the measurement recording apparatus 1 based on the hierarchical relationship in this way, the user can easily grasp the setting information.

When the “AMP” tab is selected, setting information regarding the acquisition function is displayed in the setting information input area 52 . The acquisition function is a function of acquiring measurement data such as temperature and humidity through various sensors S connected to the measurement recording device 1 .
By selecting the "AMP" tab, the user can confirm and enter setting information regarding the acquisition function. Specifically, the user can input settings related to the type of measurement data to be acquired, the input channel to which the sensor S is connected, the dynamic range (amplification factor), the noise removal filter, and the like.

When the “DATA” tab is selected, setting information regarding the recording function is displayed in the setting information input area 52 . The recording function is a function of recording measurement data acquired by the acquisition unit 20 in the recording unit 26 .
By selecting the "DATA" tab, the user can confirm setting information and input setting regarding the recording function.
FIG. 5A shows the setting input screen 50 with the "DATA" tab selected. 5A, the setting information input area 52 is formed with a function outline display 53, a parameter input area 54, and a detailed functional specification input area 55. In FIG. The function summary display 53 displays a summary guideline regarding the recording function corresponding to the "DATA" tab.

The parameter input area 54 is an area where parameters related to the recording function can be set and input. FIG. A first name input area 54b is formed.
The sampling interval is a parameter that defines recording timing (recording time interval) of measurement data. The recording destination file name is a parameter that defines the file name of the measurement data stored in the recording unit 26 .

The detailed function specification input area 55 is an area in which setting information regarding detailed functions below the recording function, which is the basic function, can be input. That is, in the detailed functional specification input area 55, a ring recording specification input area 55a, a relay recording specification input area 55b, and an external sampling specification input area 55c are formed. The ring recording specification input area 55a is an area for inputting settings related to the ring recording function. The relay recording specification input area 55b is an area for inputting settings regarding the relay recording function. The external sampling specification input area 55c is an area for inputting settings related to the external sampling function.

Here, the ring recording function, relay recording function, and external sampling function will be explained in order.
The ring recording function switches the file that stores the measurement data by a predetermined number of data points (preset number of data points, hereinafter referred to as ring recording points), and records the files that were saved in the past. are sequentially erased from the recording unit 26 .

As shown in FIG. 6, when the user operates the operation key 8 to start recording the measurement data at time T0, the measurement data acquired by the acquisition unit 20 is stored in the file A. As shown in FIG. With the passage of time, when the number of data points of the measurement data reaches the above-described number of recorded ring points, the measurement data acquired by the acquiring unit 20 is stored in file B after time T1. Then, when the number of data points of the measurement data stored in file B reaches the number of ring recording points again, the measurement data acquired by the acquisition unit 20 is stored in file C after time T2. At this time, file A is deleted from the recording unit 26 . Then, when the number of data points of the measurement data stored in file C reaches the ring recording number again, the measurement data acquired by the acquisition unit 20 is stored in file D after time T3. At this time, file B is deleted from the recording unit 26 .

After that, when the user stops recording the measurement data by operating the operation key 8 , the measurement data stored in the file C and the file D, which remain without being deleted, are stored in the recording unit 26 . On the other hand, file A and file B have been deleted from the recording section 26 . This makes it possible to save the recording capacity of the recording unit 26 while reliably recording the latest measurement data. That is, when the ring recording function is used, measurement data exceeding twice the number of ring recording points will not be recorded in the recording unit 26 at one time.

When recording measurement data using the ring recording function, the user inputs a setting (" ON”). Then, the user inputs the number of measurement data points desired by the user in the parameter "number of ring recording points" displayed in the ring recording point input area 55a2. Then, the measurement time that can be recorded in one file is displayed in the "ring recording time" parameter in the ring recording time display area 55a3.

In this way, on the setting input screen 50, it is possible to set and input whether to enable (“ON”) or disable (“OFF”) the functions of the measurement recording apparatus 1. FIG. When the function is activated, it becomes possible to input the "number of ring recording points" which is a parameter related to the function and which is an independent parameter that can be set and input by the user. When the user sets and inputs the independent parameter, the "ring recording time" which is the dependent parameter for the independent parameter is displayed. The ring recording time is a parameter obtained by multiplying two parameters, the number of ring recording points and the sampling interval, and indicates the timing at which the file storing the measurement data is switched. Note that the user cannot directly set and input the dependent parameters.
By displaying the dependent parameter on the setting input screen 50 together with the independent parameter, the user can recognize the influence of the independent parameter input by the user on other parameters (dependent parameters). As a result, even a user unfamiliar with the measurement recording apparatus 1 can recognize the role of the setting information displayed on the setting input screen 50 .

Next, the relay recording function will be described with reference to FIG. 6 again.
The relay recording function switches the file that stores the measurement data according to the maximum file capacity (preset capacity, hereinafter referred to as the relay capacity). This is a function that enables the recording of measurement data possessed by the device.

As shown in FIG. 6, when the user operates the operation key 8 to start recording the measurement data at time T0, the measurement data acquired by the acquisition unit 20 is stored in the file A. As shown in FIG. When the data capacity of the measurement data reaches the relay capacity described above with the lapse of time, the measurement data acquired by the acquiring unit 20 is stored in the file B after time T1. Then, when the number of data points of the measurement data stored in file B reaches the relay capacity again, the measurement data acquired by the acquisition unit 20 is stored in file C after time T2. Then, when the number of data points of the measurement data stored in the file C reaches the relay capacity again, the measurement data measured by the acquisition unit 20 is stored in the file D after that point.

Thereafter, until the user operates the operation key 8, the switching of the file storing the measurement data is repeated each time the data capacity of the measurement data reaches the relay capacity. This makes it possible to record the measurement data having a data capacity exceeding the maximum file capacity of one file in the recording unit 26 .
