Question 165Electricity/Electronics - 1st Asst/Chief70% to pass
As shown in figure "A" of the illustrated digital multimeter screen, what would be the significance of the symbol indicated by "1" being illuminated? Illustration EL-0047
AI Explanation
The correct answer is C) the selector switch is selected for continuity/diode test and the secondary function push button is toggled for continuity.
The symbol indicated by "1" on the digital multimeter screen is typically used to indicate that the meter is in the continuity test mode. This means the meter is set to check for a complete circuit between the test leads, which is useful for testing wiring, components, and connections.
The other answer choices are incorrect because:
A) The continuity test mode does not indicate an unsafe voltage.
B) The continuity test mode is not related to the presence of a wireless signal.
D) The continuity test mode is the intended function when the symbol "1" is displayed, not an indication of the test leads being in the wrong terminal jacks.
