Web24 Nov 2024 · Reading the Digital Display. 1. Determine the scale of the readout by looking for a “K” or “M” beside the omega. The omega symbol on your digital ohmmeter screen indicates the ohm level. However, if the resistance of whatever you're testing is in the kilo-ohm (1,000 ohms) or mega-ohm (1,000,000 ohms) range, the display will add a “K ... WebAn analog ohmmeter scale is ”backwards” from that of a voltmeter or ammeter, the movement needle reading zero resistance at full-scale and infinite resistance at rest. Analog ohmmeters also have nonlinear scales, ”expanded” at the low end of the scale and ”compressed” at the high end to be able to span from zero to infinite resistance.
