To read an ohmmeter scale, first ensure the device is properly calibrated and connected to the circuit or component being tested. The scale typically displays resistance values in ohms (Ω), with lower values on one end and higher values on the other. Read the pointer's position against the scale marks, noting any multipliers (like x10 or x100) if present. If the ohmmeter shows "OL" or infinity, it indicates an open circuit with no measurable resistance.
