By connecting it to a circuit with the power still applied. Ohm meters work best when the component under test is removed from the circuit to eliminate parallel paths of current through other components.

Should the ohmmeter be connected to the circuit while the power is being applied or only when the circuit is turned off?
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
Is a ohmmeter a pressure gauge?
No. An Ohmmeter measures electrical resistance to the flow of current.
Why should an ohmmeter never be used on an energized circuit?
Because an ohmmeter works by putting a potential difference (voltage) across a load and measuring the resulting current (the current will be inversely proportionate to the resistance). In a live circuit there is already current flowing through the load so (at best) the reading will be inaccurate, at worst the meter will be damaged.

What is the configuration of the ohmmeter?
An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.
What is ohmmeter?
An ohmmeter is a type of electrical metre that measures electrical resistance. When in resistance-measuring mode, multimeters also operate as ohmmeters. An ohmmeter measures the resistance of a circuit or component by passing electricity through it.

What are two familiar mistakes when using an ohmmeter and a voltmeter?
Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor
What should the ohmmeter read when the lead probes are touched together?
When the lead probes of an ohmmeter are touched together, the ohmmeter should read close to zero ohms, indicating a short circuit or very low resistance between the probes.
