A: Directly from whatever you are measuring as a Small current to move the coil to indicate current flow. That current can be calibrated to read voltage or current on the meter itself
The Amp meter was design to allow current flow through the meter to measure with a minimal alteration to the original circuit. That is the ideal world, in reality the meter has some resistance and will lower the current flow. The multiple current setting on most meter will reduce the effects caused by the meter but you must be careful not to damage the meter by reading to high for the setting.
A meter can be used both on the positive or negative side of a circuit when measuring current. The current going to a load should be equal to the current coming back from the load. When measuring DC current, make sure the meter should be more than adequete to be placed in series with the circuit. Otherwise, use a clamp-on meter.
You can measure the electrical current with an amp meter. Amperage measures the current flow.
The meter movement has a current flowing through a coil. That coil is on a magnet. The electromagnet with the needle moves according to the current flow. That flow is established by resistive ladders inside the meter.
Meter M3 could be malfunctioning or defective, leading to inaccurate readings. It could also be due to improper wiring or connections, causing the meter to measure current incorrectly. Lastly, environmental factors such as electromagnetic interference or temperature variations could be influencing the meter readings.
ANY METER needs some kind of current flow to operate. Internal in the meter there are batteries that provide current that when passed trough a resistor will develop voltage as a function of the current. the meter will read this current and display the resistor size to cause this current to flow.
Some of the factors that caused the "check engine" light are: defective oxygen sensors defective air mass meter emmission systems Hope this will help
disadvantage of current meter
It actually never is measured in series on a meter. AC can be measured by a meter clamp where is the coupling of flux can be measured. A normal meter will read the small voltage drop cause by current flowing through a series resistance. this small voltage drop will indicate current flow the magnitude is a function of scaling.
Electrical current is measured with an "ammeter". (The unit of current is "ampere". Measure it with an 'ampere-meter' ==> 'amp-meter' ==> 'ammeter'.)

This can occur with a permanently installed, or clamp on, ammeter, when the secondary winding is not maintained in a shorted condition. This changes the mode of the current transformer from current reduction to voltage increase, often of a substantial, lethal value.
