RANGE
All switches excepting for the power switch should be used non-locked push type switch.
The range is set to the full auto-range mode and selected by the " RANGE " key.
When the power is turned on, the mode is set to the DCV. When the auto power-off is released, the mode
returns to the previous mode of auto power-off.
The functions of HOLD, MIN/MAX, MEM, READ and REL are same as KI1 to KI5 input using lock type
switch which is explained in ( 4 ) Attached functions.
If some of switches are pressed at the same time, the input order is as follows,
Selection terminal : FC4 → FC3 → FC2 → FC1
Control terminal : KI5 → KI4 → KI3 → KI2 → KI1
