Abstract

PURPOSE: To remove erroneous operation in the range and simultaneously prevent erroneous use by generating a sound when the measuring range of a digital multimeter is changed.
CONSTITUTION: Immediately after the change-over of an AC-DC change-over switch, an L-H change-over switch 9, and a function switch 4, a buzzer 11 is actuated for a short period of time and a sound is generated. If the buzzer 11 does not ring, it is found that the switches are stopped in midway, or the change-over of the range is not carried out.
