If you hold the test leads of an ohm meter together the resistance should go to zero ohms or very close. If it doesn't you're ohm meter is malfunctioning.
ANSWER: Actually that is the first thing to do. It should show a zero reading If not the meter needs calibration adjustment. Otherwise the reading will be off by the that amount as true value.
DMM (Digital Multimeter) test lead resistance should generally not exceed 0.1 ohms to ensure accurate measurements. Higher resistance can introduce significant errors, particularly in low-resistance measurements or applications requiring precise readings. It's important to periodically check and calibrate test leads to maintain their performance and reliability.
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance
Continuity, resistance?
When a resistance measurement is taken from both primary leads tied together to both secondary leads also tied together in a transformer, and the resistance obtained is 200 Ohms -- not safe in my book.

The resistance of your body affects the measurements taken by the multimeter. By pressing the leads with your fingers, you introduce a parallel resistance path to the circuit being measured, leading to inaccurate readings. It's important to maintain a consistent contact pressure and use appropriate accessories to minimize errors.
The test equipment needs two test leads to find the resistance in a circuit.
It really depends on what you are trying to get the resistance of. A piece of copper wire 30 feet long will only have a resistance of few ohms. A person can have a resistance of several million ohms. Making sure that your meter's leads are in good contact with whatever you are measuring is the best way to get an accurate reading.
End resistance in a Carey Foster bridge refers to the resistance encountered at the terminals of the bridge when measuring the resistance of a conductor. It arises from the contact resistance at the junctions where the measuring leads connect to the bridge and the resistor being tested. This resistance can affect the accuracy of the measurements, so it is typically minimized or compensated for in precise applications. The design of the Carey Foster bridge helps to balance and measure small resistance changes effectively, despite the presence of end resistance.

The resistance across both leads would be cumulative. 95+75= 170 Ohms
Zero ohms.
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.
A diode should show low resistance with the leads hooked one way and show an open with the leads reversed
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance
If when you said "resistance" you actually meant resistor, this component is called a potentiometer (see image for an example).If that is not what you meant, then I cannot begin to guess what you are referring to, as resistance is a quantity not a component and thus cannot have physical leads (and I have been involved with electronics since 1967 and worked in the field for 30 years).
