Why can't you use a multitester as an ohmmeter if it has no battery?

The battery is used by the meter to apply a voltage across the resistance being measured and determine the current which determines the resistance. If there is no battery it can't supply the voltage and can't measure current, so no reading.

What device is used to measure the resistance of a resistor?
You can use a multi-meter to measure resistance. The specific portion of the meter for measuring resistance is called an ohmmeter.
Do robots use the bathroom?
No robots cant use the bathroom they simply have no Bladder so they cant ever have to go
Is it safe to charge a battery while in use?
This depends on the type of battery. Car batteries are always charged while in use. With other types of batteries, this is not recommended and may result in a battery explosion or damage to the device the battery is powering.
What ohms setting do you use on a meter for 240v electric heater?
Whenever you use an ohmmeter, you must first ensure that the device you want to test is disconnected from the supply. So the fact that your heater is rated at 240 V is irrelevant to this question. The heater must be disconnected from the supply BEFORE you contemplate measuring its resistance. Which 'ohms setting' to use is then simply determined by whichever setting gives you the best reading. For an analogue ohmmeter, this is whichever setting results in the pointer being towards the lower-resistance end of the scale.
Ohm meter mean and their use?
An ohmmeter is an electrical instrument that measures electrical resistance, but instead of hairsprings to supply a restoring force they used conducting of the first pair of leads and their contact resistances is ignored by the meter.
How do you take care of an ohmmeter?
Never connect the ohmmeter's leads across a voltage.On an analog meter, adjust the zero before use.Turn your ohmmeter off when not in use, to protect against voltage drain.When your ohmmeter's battery is low, or your meter won't be used for a while, remove the battery to prevent damage to the meter from battery leakage.
Why can't you use a mutitester as an ohmmeter if it has no battery?
An ohmmeter works by applying a voltage, and measuring the corresponding current. This is an application of Ohm's law: resitance = voltage / current.
Why can you use soda in a battery?
you cant because the battery wont be useable anymore :D
Two practical requirements for Optimising the accuracy of resistance measurements for a given ohmmeter?
1). Assure a fresh battery in the meter. (A digital ohmmeter with a low battery will often display a reading as if it's the honest truth, when it's actually a completely bogus measurement.) 2). Use the smallest scale possible, i.e. the lowest scale that's larger than the resistance under test.
How can you chack the cdi an altcrnator?
One way to check the CDI on an alternator is to use an ohmmeter. If you do not know how to use an ohmmeter, you may be better off by taking your vehicle to a repair shop to look at the alternator.
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 job you do need to use a ohmmeter?
Electrical engineer, radio/TV repairman.
How do you determine if the capacitor is defective?
To determine if a capacitor is defective, use an Ohmmeter of a Multimeter.
What if your ipod is brand new and fresh out of box but i cant get it on?
You have to let it charge to full battery first then use it.
Can you use Nokia sim in Samsung?
Yes you can use a nokia sim card in a samsung just u cant cahange your battery!
What condition is unfavorable for the use of an ohmmeter?
An ohmmeter is used to check continuity and resistance. An unfavorable use would be to connect the meter to any power. Unless the meter has a safety feature, connecting it to any type of power will damage the meter.
When using an ohmmeter to check the resistance of a compressor's windings what scale would you use?
the lowest
