7.5 Checking Fuses(During Earth leakage
current and protective conductor cur-
rent measurements)
1.
Press on the initial screen to
display the system screen.
2.
Press to open the fuse check
screen.
3.
Press to start checking.
"OK" indicates that the check completed success-
fully.
NG indicates that the fuse for the Earth leakage
current or protective conductor current detection
circuit may be blown.
Contact your dealer or Hioki representative.
4.
Press to return to the system screen.
Check every time the power is turned on:
Select or to determine whether or
not this check be performed every time the
power is turned on.
•
The current detection circuits for modes other than Earth leakage current and
protective conductor current measurements also contain fuses. Check such
fuses in the pre-work inspection.
•
Internal fuses include the power supply fuse.
Use the VA check function to check the power supply fuse.
See "Fuse inspection (when using modes other than Earth leakage current and protec-
tive conductor current modes)" (p. 42)
•
Do not connect a device under test during a fuse check.
•
Supply power via [LINE IN] and turn the circuit breaker On as a fuse check
will otherwise not operate normally. Always confirm this before performing a
fuse check.
