When performing resistance measurements with an analog meter, what should be done to adjust the indicator correctly?

To ensure accurate resistance measurements with an analog meter, it is essential to calibrate the meter properly before taking any readings. This involves shorting the test leads together and adjusting the "0 Ω Adjustment" control. By doing this, you reset the meter to indicate zero ohms when the leads are in contact. This step is crucial because it accounts for any variations or errors in the meter itself, allowing for more precise resistance measurements when testing components or circuits later on.

Connecting the meter leads to a circuit or leaving the meter connected while adjusting does not provide an accurate zero reference, which is essential for resistance measurements. Disconnecting the meter from all circuits may seem like a good idea for safety, but without shorting the leads first, you will not achieve the necessary calibration for an accurate reading. Calibrating the meter before each use can be beneficial, but the specific adjustment procedure of shorting the leads is what directly ensures the meter is set to read zero ohms accurately.
