You check and adjust instrument zero and, if you are measuring ohms, you also check and adjust ohms zero.
Basically, your series and shunt ohmmeters differ in circuit configuration. Your series ohmmeter is configured in a way that your "meter" (which has internal resistance) is connected in series to your "measured resistor" and we all know that those TWO resistances will ADD up causing some sort of inaccuracy. While on the other hand, your shunt ohmmeter is configured in a way wherein your "meter" is connected in PARALLEL to your "measured resistor" that will ease-up the inaccuracy but will only measure resistances ranging from 200 Ohms to 400 Ohms (typically and depending on your configuration).
It would be the sum of the two resistances, as they are connected in series.

To adjust for the changing (dropping) voltage of the internal battery, so you can still get accurate readings. When you can no longer adjust to zero, replace the battery(s).
it is measured in Ohmmeter Ohms
An ohmmeter measures ohms. These are the measurement of electrical resistance. The symbol for ohms is the capital Omega symbol, a symbol that resembles an upside down horseshoe.
check the batteries
An ohmmeter measures electrical resistance. This is one part of "impedance", that prevents electricity from flowing freely from one part of a circuit to another. Resistance is measured in "ohms".
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.
The reading will be very close to zero ohms.
You check and adjust instrument zero and, if you are measuring ohms, you also check and adjust ohms zero.
Set it to infinite which may be a sideways 8. When you touch the leads the needle should swing to zero. If it comes to rest on a different number such as 10 then change the batteries. If it continues to give the same reading then you may need to replace it.
A: To read ohms you will use it by reading in parallel and without any external voltage applied
It depends on the model and style of ohmmeter. Insert test lead connectors into the ground socket and the socket marked for ohms (it may also be marked for other things). There should be a dial to rotate to an ohms setting. Connect the other ends of the leads to the device for which resistance is being measured and read the meter. WARNING: be sure the component being tested is not connected to any power source or you risk burning out the unit.
