Set your multimeter to the highest resistance range available. The resistance function is usually denoted by the unit symbol for resistance: the Greek letter omega (Ω), or sometimes by the word “ohms.” Touch the two test probes of your meter together. When you do, the meter should register 0 ohms of resistance.
How do you do a Ductor test?
Ductor testing is usually performed using a micro/milli-ohmmeter or low ohmmeter. The criteria for evaluating the contact resistance greatly depends on the metallic surface area, the contact pressure, the type of connection (ex. soldered, bolted, clamped, welded, etc.) and so on.Jul 1, 2015

What is micro ohm meter used for?
Micro-ohmmeters (microhmmeter or micro ohmmeter) make measurements of low resistance. Megohmmeters (also a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is the ohm (Ω).
How does an ometer work?
The working principle of ohmmeter is, it comprises of a needle and two test leads. The needle deflection can be controlled with the battery current. ... Once the two test leads of the meter are connected to the circuit then the battery gets discharged. When the test leads get shorted then the rheostat will be adjusted.
