Measurement Mode
the DCV measurement mode.
( 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.
