In the unknown of measuring the voltage what should be the setting of VOM selector?
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
Do you unplug before measuring resistance?
Yes. Measuring resistance involves imposing a small current through a device and measuring the voltage drop. If there were any other source of voltage, the reading would be in error. You could also damage the ohmmeter if there were an external voltage source. You should also take the device out of circuit before measuring it, so as to not bias the results by the resistance of other devices in the circuit. It all depends on the situation, for which you are responsible for evaluating before you start.
Is the open circuit voltage of a solar cell measured under non-illuminating condition?
Well, you should really measure the open-circuit voltage and the short circuit current both under dark and light conditions and then compare them to fully characterize a solar cell. Measuring the open-circuit voltage means measuring the voltage across the cell when no current is flowing (i.e., with a LARGE resistance as a load on the cell). Measuring the short-circuit current means measuring the current when the voltage across the circuit is essentially zero (i.e., with a VERY SMALL resistance as a load on the cell--thus, "short-circuit" current).
When measuring an unknown voltage with an analog VOM you should first?
For any value turn the multimeter to the highest scale in the value that you are measuring. By doing this you will not overload the meter by using a lower scale to measure a higher value.
How should a ammeter and voltmeter be connected in series?
no. you want to measure across the desired circuit segment. whether you are measuring voltage drop or current.
When measuring voltage the probes should be connected in?
can some one please tell me when measuring voltage the probes should be connected to sequence or series?
What precautions should be used with a tilt table test?
Precautions are few with the tilt table test. However, when any drug is used with this test, the appropriate precautions for that particular drug should be observed
Are JumpSmart trampolines safe?
There are a group of safety precautions which must be observed. If these are observed, then the trampoline is safe. Children should be monitored.
Precautions that should be observed when working with sheet metals?
There is a few precautions you should take when working with sheet metal. You should always wear safety glass, wear gloves an pay attention.
When measuring resistance what should done to the supply voltage?
supply should be off
What precautions with regard to laparoscopy should be observed?
patients should notify their physician of any medications they are taking (prescription, over-the-counter, or herbal) and of any allergies. Precautions vary due to the several different purposes for laparoscopy.
Why should you observe safety precautions while caring for animals?
When caring for animals, and in all your other activities, you should practice appropriate safety precautions because you do not want to be injured or worse, and precautions help you avoid that.
In the unknown of measuring the voltage what should be the setting of VOM selector?
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
What range should you set the voltmeter prior to taking a voltage measurement?
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
When measuring voltage how should test probes be connected?
First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
What precautions as to phenobarbital use should be observed?
Dosages should not be exceeded. It is also important to adhere to the proper timetable for use of the medication. Use of the drug should not be discontinued without consulting a physician
What are the safety precautions for the electronic balance?
Safety precautions that individuals should follow for electronic balances are to make sure users have the right voltage and to make sure that they have the correct power supply. Failure to do this can lead to harm.
