PROBLEM TO BE SOLVED: To provide an efficient fault information holding system. SOLUTION: During a regular operation, a battery is not mounted in a battery mounting adapter 7 and power is supplied (a) to a package 3 from a power module 4. When a fault occurs and the exchange of the package 3 is required, the battery having same rating as the power module 4 is installed on the battery mounting adapter 7. The package 3 is pulled out while the power of a casing is turned on as it is after power is fed to the feeding part 6 of the package 3. Since the package 3 holds a state when the fault occurs, it can start fault analysis work as it is by installing it on a package tester with hot line. |
