LOC
Key lock
0: No key lock
1: Prevents operations from being changed except for the
changing of SP in the operating display
2: Prevents all parameter changing operations
—1: Set -1 to enter the setup parameter setting display.
But if LOC=1 or 2 is already set, the parameter
value can not be changed by setting LOC=-1 only. To
change the parameter value, set LOC=0 at first (for
disabling keylock), then set LOC=-1 once again.

Settings:
When the display value is — — —, the heater current is not being measured.
