Which of the listed statements is correct when using a digital multimeter set up as an ohmmeter?

AWith the test leads shorted together, a reading of 'zero' ohms will be displayed.
BWith the test leads apart insulated from each other, a reading of 'zero' ohms will be displayed.
CWith the test leads shorted together, a reading of 'OL' ohms will be displayed.
DIt is usually not possible for a digital multimeter to be set up as an ohmmeter.
AI Explanation

The correct answer is A) With the test leads shorted together, a reading of 'zero' ohms will be displayed. This is correct because when the test leads of a digital multimeter are shorted (connected) together, the multimeter is measuring the resistance of the test leads themselves, which is essentially zero ohms. This allows the multimeter to display a reading of '0' ohms, confirming that the test leads are properly connected and functioning as an ohmmeter. The other options are incorrect: B) is wrong because having the test leads apart and insulated would result in an 'overload' or 'OL' reading, not zero ohms. C) is also wrong, as 'OL' would indicate an open circuit, not a short circuit. D) is incorrect, as digital multimeters are commonly equipped with an ohmmeter function.
