That is, in the conventional measurement environment condition setting method, by pressing the touch panel 51a, the measurement environment conditions of the leakage current measuring device can be made to conform to various measurement standards. However, when measuring according to another measurement standard after completing measurement according to one measurement standard for a specific measurement item, first, the measurement environment conditions of the measurement standard for which measurement has been completed and the measurement environment conditions for other measurement standards must be determined. It is necessary to confirm the difference between the two using a standard manual or the like. Next, all the different measurement environment conditions must be reset by pressing the touch panel 51a. Similarly, at the beginning of power-on,

When the measurement environment conditions are first set,
In addition, erroneous measurement may be performed due to misreading of the standard manual at the time of resetting or erroneous setting of the measurement environment condition due to an operation error of the touch panel.
In such a case, it may be erroneously determined to be normal even though the insulation resistance is deteriorated, and in some cases, there is a problem that an electric shock accident may be caused.
