(2-1-2) Range setting ( Lock type & Auto-Ranging : KMS = RMS = " H " )
The range shown in below table is controlled by a switch of the RC0 terminal which must go to " L " level
( GND ) when it is pressed. When the switch is pressed once, the range is changed from Auto-range to
manual-range, and its range is held. Then, the range is changed in every time by the switch operation. The
range always returns to Auto-range from any kinds of range when the switch is pressed over than 1 second.
