The setting step S3 may include setting at least one of the first conversion unit 41, the amplification unit 43 and the second conversion unit 42 based on the matching information obtained through the matching step S2. Set either one.

The setting step S3 may be performed according to the operation of the memory unit 13 and the setting unit 40. [

The setting method of the multifunctional portable measuring instrument described above is described as being performed through one setting unit 40 or one setting control unit 44 corresponding to one sensing unit 20 or one measurement sensor unit 22 However, the present invention is not limited thereto.

For example, the setting method of the multifunctional portable measuring instrument includes the setting unit 40 having a plurality of sensing units 20 corresponding to the sensing unit 20 or the plurality of sensing sensors 22, (44). &Lt; / RTI > In particular, the matching step S2 and the setting step S3 may be individually performed by the setting control unit 44 provided in a plurality of ways according to the 1: 1 correspondence.

As another example, when setting a plurality of signals to be sensed by the sensing unit 20, the setting method of the multi-function portable meter may be performed collectively through one setting unit 40 or the setting control unit 44. At this time, one of the setting unit 40 or the setting control unit 44 may also set the signal delay unit 45 or the signal multiplexing unit 46. In addition, the setting controller 44 may be configured as one to specify the signal delay unit 45 or the signal multiplexer 46.

The method of setting the multi-function portable meter according to an embodiment of the present invention may further include an operation selection step (S4).

The operation selecting step S4 selects whether the sensing unit 20 is operated after the setting step S3. The operation selection step S4 is performed after the setting step S3, and it is determined that the setting is finally completed.

The sensing unit 20 senses an object to be measured while the sensing unit 20 is coupled to the housing unit 10 and the sensing signal of the object to be measured is transmitted to the setting unit 40. [ Or through separate control means.

For example, the operation selecting step S4 may be performed by connection of the measurement sensor unit 22 and the setting unit 40. [ The sensing unit 20 is operated by connecting the sensing unit 20 to the housing unit 10 in a state where the setting is completed and the measurement sensor unit 22 at the measurement position generates a sensing signal of the measurement object .

As another example, the operation selecting step S4 may be performed according to the operation of the operation selecting unit 124. [ When the operation selection unit 124 is operated in a state where the setting is completed, the measurement sensor unit 22 generates a detection signal of the measurement object at the measurement position.

The detection signal of the specified measurement object is converted through the first conversion unit 41, the amplification unit 43, and the second conversion unit 42 that have been set through the setting method. Here, the detection signal of the specified measurement object may be converted in at least one of the signal delay unit 45 and the signal multiplex unit 46, which have been set through the setting method.

The setting method of the multi-function portable meter according to an embodiment of the present invention may further include a calculation step (S5) and a setting evaluation step (S6). The calculating step (S5) and the setting evaluation step (S6) can be performed in two ways.

For example, the calculation step S5 calculates the evaluation index Y using the input information input through the preparation step S1 and the setting constants stored in the memory unit 13. [ More specifically, the calculating step S5 calculates the evaluation index Y through the following equation 1 using the setting constants selected corresponding to the input information in a 1: 1 correspondence between the input information and the setting constants . Here, it can be understood that the larger the evaluation index (Y) calculated finally, the best environmental condition is established.

a is a proportionality constant of the calculation formula included in the setting constant,

Ii is an important constant according to the evaluation criterion among the setting constants,

Yi is an evaluation index for the evaluation item,

Y is the final calculated evaluation index.

The setting evaluation step (S6) compares the evaluation index (Y) finally calculated through the calculation step (S5) with a predetermined evaluation index.

As a result of the comparison of the setting evaluation step (S6), if the evaluation index (Y) calculated through the calculation step (S5) is equal to or larger than a predetermined evaluation index, the setting can be finally completed.

As a result of the comparison of the setting evaluation step (S6), when the evaluation index (Y) calculated through the calculation step (S5) is smaller than the predetermined evaluation index, the setting step is changed again and the calculation step do.

Here, the order of execution of the calculation step (S5) is not limited, but may be performed prior to the setting evaluation step (S6) in a state in which the input information and the setting constants are acquired.

The order of the setting evaluation step (S6) is not limited, but may be carried out after the calculation step (S5) and before the operation selection step (S4).

As another example, the calculating step S5 calculates the evaluation index Yk by using the input information inputted through the preparation step S1 and the setting constants stored in the memory unit 13. [ More specifically, the input information input through the preparation step S1 and the setting constant stored in the memory unit 13 are used, and an important constant Ct (k) according to the upper limit value of the evaluation criterion among the setting constants ) And the important constant Cb according to the lower limit of the evaluation criterion among the setting constants, the evaluation index Yk can be calculated through the following equation (2). Here, it can be understood that the higher the relative evaluation index among the k calculated evaluation indexes Yk, the better the environmental conditions are.

The setting evaluation step (S6) compares the relative evaluation values of the k evaluation indexes (Yk) finally calculated through the calculation step (S5).

As a result of the comparison in the setting evaluation step (S6), the setting constant is updated in correspondence with the largest evaluation index among the k evaluation indexes (Yk) finally calculated, and the setting is finally made through the input information and the updated setting constant . &Lt; / RTI >

Here, the order of execution of the calculation step (S5) is not limited, but may be performed prior to the setting evaluation step (S6) in a state in which the input information and the setting constants are acquired. The procedure of the setting evaluation step (S6) is not limited, and may be carried out after the calculation step (S5) to before the operation selection step (S4).

It is also possible to stabilize the connection state between the setting terminal 31 and the sensing terminal 32 to prevent the sensing terminal 32 from being disconnected from the setting terminal 31 arbitrarily while maintaining the connection state.

It is also possible to set the processing conditions of the sensing unit 20 to be replaced to match the existing measurement algorithm so that the existing measurement algorithm can be set to match the sensing unit 20 to be replaced, It is possible to process the signal detected through the antenna 20 by the existing measurement algorithm.
