How is the milliamp scale on a meter checked
WebA meter designed to measure electrical current is popularly called an “ ammeter ” because the unit of measurement is “amps.”. In ammeter designs, external resistors added to extend the usable range of the movement are connected in parallel with the movement rather than in series as is the case for voltmeters. WebA multimeter is used to diagnose 4-20 mA analog signal control loops. In process water chlorination, sensors detect chlorine levels and send signals to a controller. The controller then sends a 4-20 mA analog signal to a chemical pump. At 4 mA, the pump is turned off, and at 20 mA, chlorine is pumped at a maximum rate.

WebThis is the flow measured by the flow transmitter that you wish to convert to a 4 to 20 milliamp current output reading. Low Limit. Enter the lowest flow that the flow transmitter will measure. For example zero would be a typical value for most flow transmitters, but you can also add negative (-) or positive (+) values as well.
