You must slightly increase the resistance of the internal shunt.
-- The exact amount depends on the characteristics of the meter movement
without the shunt.
-- The process will involve something like filing small notches in the existing shunt
until the meter's full-scale has changed to what you want.
-- But that plan raises the whole new issue of how you'll measure the changes
while you're filing.
Judging by the fact that you asked the question, my opinion is that you'll find it
faster, easier, and more effective to simply buy a new 500 mA meter, rather than
run the risk of ruining the perfectly good 1 Amp meter that you have now.

How do you play a tc baritone scale sheet?
You play it as written in concert pitch. For example, the C scale will show 2 sharps, but you play it as a C scale, no flats/no sharps. You have to transpose the notes down a step, so you will actually be playing a C and reading a D. It would be easier to learn to read bass clef!
How do i check a music Instrument cable using a multimeter?
Set the meter to ohm function. then put the leads on either end of the cable. it should read 0 if its good infinite if its bad
What is the meaning behind the quote, “of course we may have to change remedies if we don’t get results.”explain?
it means 'We will have to change or add to what we know if it doesn't work soon'
How do you tell if the alternator is bad in a 2000 jeep Cherokee sport?
Borrow a digital DC voltmeter, attach the meter to the positive and negative battery posts, if the battery is healthy and fully charged it should read 12.68 volts, now start the engine and monitor the voltmeter, if the battery is fully charged and the alternator is healthy the meter should read 14.2 volts (give or take .3). If the voltage fails to reach that goal the alternator is probably faulty.
Where can you read full Cherub books online?

How do you read a forcemeter?
To read a force meter, you simply look at the measurement displayed on the dial or digital screen. Make sure to note the units of measurement (usually Newtons) and the scale of the meter to interpret the force applied accurately.
You have an avc avometer transformer 100 amps 100 ma it says to use with avc model 7.8 heavy duty avometers it looks old what is it used for?
Measuring currents to 100A A.C. You set the meter to 100 mA and connect the transformer output to the meter. When the primary current is connected the meter will read the current flow. Full scale (100mA) then means 100A in the transformer, so you multiply the scale reading by 1,000.
What value of resistance is used to convert galvanometer into voltmeter?
It depends on the resistance of the galvanometer and its full scale current. A 100 ohm meter reading 1 milliampere would require 0.1 volts to reach full scale, so it would require about 0.1 ohms in parallel to become a 1 ampere ammeter.
How is an amp meter connected to a three phase distribution system?
In a three phase service distribution the amperage is monitored by current transformers that are connected in series with with the incoming bus bars. These CTs are rated in a ratio for the size of the service. A 1000 amps service will use three 1000:5 ratio CTs. The numbering on the face of the meter will correspond to the size of the service. In this case the meter face will read from 0 to 1000 amps. So for a 1000 amp on the bus bars, the meter connected to the CTs will read full scale deflection at 5 amps. For 500 amps on the bus bars, 2.5 amps on the meter will show half scale or a meter face reading of 500 amps. Panel meters are sized in full scale deflection, for amp meters 5 amps and for volt meters 5 volts full scale. Installations these days use a power monitiring system. It still has inputs from PTs and CTs but the output on the electronic metering displays will give you anything that you need to know about the incoming service. Voltage, amperage, power factor, wattage, line to neutral voltages, and line to line voltages are a few of the read outs that the customer has access to.
If 2 equal weights are attached to a fish scale on each end so that the full exertion of force from the weight is transferred into the scale would the scale read the weight of 2 weight's worth or one?
if the weight is distrubted equally then the scale will read 2 weights worth
What is the resistance of a blown fuse?
Infinite...a blown fuse is an 'open' in electronics terms. Infinite resistance.It will not read zero on a digital multimeter, it will read as a maximum resistance.A fuse, when good, has zero (practically speaking) resistance. When it blows, it has infinite resistance, thus on a multimeter it will provide a high reading.... When an analogue (not digital) multi-meter is set to ohms it will read zero when blown. If you touch both leads off the meter it will read full scale. if the leads are NOT touching the meter will read zero. so if your fuse is blown it will act like the leads are not touching because it is blown. It is good practice not to touch the exposed lead ends or the fuse under test as the resistance of your body can give a false reading.The ohm scale on an analog multimeter is reversed...when the meter is at the far left, what you might think is zero, it is indicating infinite resistance. When you try and determine the resistance of a fuse that is blown, the meter will not move from the left side of the scale. That is not zero resistance. That is infinite resistance.
What are parallax errors in a scale?
When a readng is taken from an analog meter, the pinter must be viewed correctly as it is a short distance away from the scale, so if read from one side, an error of several divisions will occur. To avoid this error the meter should be read from a position directly above the pointer. To help avoid this error most meters have a mirror in the scale so that the error may be dicerned more readily.
Why the zero of the ohmmeter scale is usually at the right end of the scale and reading increase towards the left?
Because the meter is actually measuring the current through the resistor, and the two quantities ... current and resistance ... are inversely proportional. So when the meter measures more current, it has to read less resistance, whereas higher resistance will result in less current. So the numbers for resistance have to be printed "backwards" on the meter scale.
What will happen if we use current transformer of different rating for each phase in three phase supply?
A current transformer has to have the same ratio as the meter that it drives. Full scale deflection on the meter is 5 amps which equals the maximum allowed current on the phase that it is reading. A different ratio on the CT to meter would show an erroneous reading on the meter depending on the ratio of the connected CT. To keep costs down the meter is common to all three phases and is read by connecting the meter to the phase CT through a three position switch.
Can the elecompten read a meter in there office when your meter is broke?
Nope, when the meter's broke there ain't no-one can read it.
What are the differences between read-only and full access?
Read-Only-Memory is a file that you can ONLY read. You cannot edit, alter or change this in any way. When it is Full Access, you CAN edit it.
What should a full charge read on a battery for a BMW?
With engine not running it should read 12.6 volts if it is fully charged. You will need a digital volt meter to check it.
