In the protective case shown in FIG. 10, since the test lead cable must be folded and stored, the cable storage is troublesome, and the detachment from the protection case and the measuring instrument is troublesome.
In the protective case shown in FIG. 11, since the cable is wound around the protective case, the cable is exposed outside the protective case even when the case is closed. For this reason, the cable may be rubbed against other external members during the work or while being carried for the work, and the cable may be damaged.
In the case where the cable is wound around the measuring instrument main body in FIG. 12, the housing of the measuring instrument may be damaged, and the length of the cable needs to be shortened in order to maintain compactness.

Further, a portable measuring device is not always used on a table, and sometimes it is desired to mount the measuring device on a wall or the like. For example, when trying to measure voltage with a switchboard, etc., you may want to take your hand away from the measuring instrument. In some cases, measurement must be performed.
When the measuring instrument is housed in the protective case shown in FIG. 10 of the spread notebook system, there is no holding means for protruding and holding the probe part of the test lead from the protective case, and thus the probe of the two test leads is used. It has been practiced that there is a problem with the safety of measuring with the right hand as if holding the chopsticks and holding the protective case with the left hand.

  When measuring by suspending the measuring instrument with a suspending tool having a magnet as shown in FIG. 13, it is not necessary to hold the measuring instrument by hand, and the probe portion of the two test leads is not held by one hand. Therefore, there is no problem in safety, but since the measuring instrument itself is not fixed, it may shake during the work and hinder the work, and the workability is not good. In addition, since it is difficult to manufacture a two-page notebook type protective case by integral molding, it cannot be manufactured inexpensively.

(Effect of the present invention)
The measuring device 100 is fixed to the housing by the locking projections 18a and 18b of the side wall 14a of the case main body 11 and the side wall 14c. The magnets 42a and 42b can be fixed by being sandwiched between the measuring instrument 100 and the bottom plate 12. Therefore, there is no need for bonding or screwing for fixing the magnet. The attachment and detachment of the magnet is easy, and the presence or absence of the magnet can be selected as needed. The magnet can be removed and used when it is not necessary to attach it to a wall, such as when measuring on a desk.
Conversely, when performing a measurement operation with a switchboard or the like, a protective case can be attached to a wall of the switchboard or the like with a magnet to perform the measurement, thereby facilitating the measurement operation and increasing convenience. Further, since the protective case is a vertically opened protective case, and the lid 20 is located below the measuring instrument, when the protective case is attached to the wall and fixed, it does not obstruct the measurement unlike the lid of the double-sided protective case. There are advantages.

On each of the upper, lower, left and right surfaces of the protective case, the lid portion 20 and the bottom plate portion 12 are formed in a flange shape, and the test lead cable is housed in the flange, and is provided outside the protective case. Since the cable is not exposed, even when the protective case is stored in the work bag or the like, there is no possibility that the cable rubs against another member or the like and is damaged.
Since the barrier portion of the probe portion of the test lead can be sandwiched between the notches 19 and 26 provided in the protective case, the probe portion can be stably fixed. In addition, since the contact of the probe part of the test lead can be projected out of the protective case and fixed by the holder 16, the test lead can be brought into contact with the terminal of the measurement object while the test lead is fitted in the protective case. Can be done. In addition, since the position of the barrier section of the probe section can be set to a plurality of types, such as the holder 16 and the notch 19, it is possible to fix test leads whose measurement categories can be converted.
Since the protective case can be made to stand by itself at a certain angle, the display of the measuring instrument can be easily visually recognized when performing a measuring operation on a desk.
Since one of the test leads can be fixed and attached to the protective case, it is possible to carry out the measurement operation of holding the protective case with one hand and measuring with the other test lead with the other hand.
Since the lid is made of a transparent or translucent material, the display of the measuring instrument can be confirmed even when the lid is closed.
