A Volt-Ohm-Milliammeter, often called a multitester, can measure current on more than one scale. It's natural to see a new device and wonder how it works. Fortunately, most people can learn how to use a multime
Electric current is the flow of electric charge and is measured with an ammeter. The SI unit for measuring electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second. While there are several methods of measuring current, the most common method is ...
Switch off the motor, and then disconnect one of the wires powering the motor. Attach your ammeter or digital multimeter set to measure DC current; attach it between the motor and the detached wire. Always wire ammeters in series with a circuit, placing them between the power source and the...
How to Check a Cell Phone Battery Step 6 Set your ammeter in the range of amperes from Step 1. If you are using a multimeter, set it to measure amperes, and set the range. For example, if the battery is labeled 30 amperes, set your meter between 25 and 35 amperes. Step 7 Attach ...
Note: while the DMM settings described in this article were written to describe using a Fluke DMM, most digital multimeters will have very similar controls and will use similar measurement procedures. At left our photo illustrates the Sperry DSA-500 clamp-on multimeter/ammeter reading 0.28A (Amps...
Step 1: Test the thermostat with a VOM (multimeter) set to the RX1 scale. The thermostat is located directly on the back of the control knob that regulates the heat. To gain access to the thermostat, remove the back service panel to the control panel. Step 2: Disconnect one electrical ...
Note the picture shows the multimeter set to thermometer instead of ammeter Also while doing this, I had to read back the current measured by IC81 itself. For this, I used aDigital Discoveryconnected to the I2C interface header on the Genesys ZU (J36): DIO24 to SCL, DIO25 to SDA, an...
Multimeter Method In present days, one of the most common methods to measure the voltage is by using a multimeter. The multimeter can be either analog or digital butdigital multimetersare most commonly used because of higher accuracy and low cost. ...

Voltage is measured across the terminals of the power source (just as measuring the height of the overhead tank). Current is measured inside the circuit (similar to measuring water with a flow meter). Current is measured using an ammeter, which is included in a multimeter. ...
