what is a 4 digit multimeter?
351593
a multimeter that can display up to 4 digits, that is not a bad one, but they make ones with 6 digits. i have one from radio shack that has automatic voltage ranging and push button switching between ac and dc. it also has ac field detection and all kinds of other goodies. if you are going for a multimeter, go for a good one, because they last a long time and come in handy when you need those extra features. trust me, i went from a 12 range analog meter to a 42 range digital, BIG difference.

The simplest voltmeter is made from a sensitive current meter (e.g., 20 microamps full-scale) in series with a resistor. The resistor is computed from the desired full-scale voltage and Ohm's law (E=I*R). Thus a 100 volt voltmeter can be made from a 20 ua meter and a series resistance of 100/.000020=5 megohms. (Actually the resistance of the meter should be subtracted from the series resistor so the total is 5 megohms, but meter resistance is usually negligible compared to the total resistance needed.)

There are multiple units usable.  Try pascals, psi, torr, atm

what it means is this 4 plus negative .01 and with the other it's 5 plus negative .04 its simple. if you know what it means and if you took notes look at them. it may help a little

k.t.400 took pains to give u a list. Choose what u want, else please be clear in questioning. 100meter is 100 times of 1meter by definition.

As you go back in time, the electrical measurements were not always measured with a digital display.\n\nWhen you are using an analog device - the measurement or reading was shown by a needle or indicator - which is designed with an electro-mechanical principle - based upon electrical deflection in a magnetic field and has been calibrated with a spring loaded element. The springs in pressure gages as well as electrical devices are not always perfectly linear and have a chance to be sticky at the low end ( that is why they always ask you to tap these devices lightly before taking a reading ). Therefore to reduce this error the measurements in analog meters were moved to 4-20 mA, 10-50mA, 1-5 V etc.\n\nHowever with a digital readout device there is no such need, but the continuity wherever it exists is based on the analog measrement history.\n\nThe same is applicable to the pneumatic devices where the signals are of very low pressure vaues such as 3 -15 or 3 -27 psig etc.

such a no. cannot exist but hey dude a great question lets look at it this way\nthe last digit of the given no. will be 6\nand the resulting no will be 4 times that no\nlast digit of 4*6 is 4 so the resulting nos last digit digit has to 4 \nthat would mean the first digit of the original no will  be 4\nso just as an eg let us consider the no. 46\n46*4 will be 184\nthat is the first digit will be 1(or 2 or 3 or 4 but never 6)\nthis will be followed by every no \nso u c such a no just canno exist

Look for caliper (spelling counts).  Specifically, Vernier Caliper, and micrometer.  \n\nThose are the two major precision measuring tools.  Try the starrett.com web site.  They have a sterling reputation for quality.

I don't think you will find a circuit diagram for a digital water (fluid) meter so easily. But let's analyze what you need to build one:\n1) A flow sensor (a "turbine" wheel that outputs pulses), tricky to build a reliable one by yourself....\n2) A counter,  see http://www.kpsec.freeuk.com/counting.htm\n3) A display, and its driver.\nUnless you want to buy a complete electronic flow meter, like  http://www.rittenhouse.ca/asp/product.asp?PG=1553\nor more "professional",\nhttp://www.flowmeters.com/products/index.cfm?task=cat_prod_page&master=yes&master_cat_id=29&cat=yes&cat_id=163#29_163

Theres a tool called a Handheld Anemometer, amazon has one inexpensive

a meter often has four or five dials..it depends upon the standard. Now if it happens that your meter does not have the standard number of dials then a meter multiplier is applied to meet the standard.
