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.
What else can I help you with?
DMM test lead resistance should never excced?
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.
What refers to the tendency of oil to resist flowing?
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
When checking a diode with an ohmmeter when the meter leads are connected to the diode the meter should show a resistance. If the meter leads are reversed it should show infinity.?
When checking a diode with an ohmmeter, you should see a low resistance reading when the positive lead is connected to the anode and the negative lead to the cathode, indicating that the diode is forward-biased and conducting. Reversing the leads should show infinite resistance, which means the diode is reverse-biased and not conducting. This behavior confirms that the diode is functioning properly. If you see low resistance in both directions, the diode may be faulty.
What type of curcuit measurement is made by placing a meters test leads in parallel with a deenergized component?
Continuity, resistance?
A measurement of 200 ohms is obtained between the primary and secondary of a double wound transformer is it safe to use?
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.

What varies as you press the leads of a multi-meter with your fingers?
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.
How many test leads are needed to find resistance?
The test equipment needs two test leads to find the resistance in a circuit.
What part of the ohms scale of a meter are the most accurate resistance measurements made?
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.
What is end resistance in Carey foster bridge?
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.
Insulin deficiency or resistance leads to hyperglycemia and ketoacidosis?
Diabetes Mellitus
What is the resistance of two extension leads of 95 ohms and 75 ohms when connected together in series?
The resistance across both leads would be cumulative. 95+75= 170 Ohms
When the leads of the meter are touched together a nd the meter is set to measure resistance what should the resistance reading be?
Zero ohms.
Why one of the leads of resistor connected in electronic circuit is opened while measuring its resistance?
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.
When performing a diode test is necessary to?
A diode should show low resistance with the leads hooked one way and show an open with the leads reversed
What refers to the tendency of oil to resist flowing?
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
What is the variable resistance with 3 leads?
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).
