# Can multimeter measure microamps?

## Can multimeter measure microamps?

Designed for heating ventilation and air conditioning (HVAC) technicians, the Fluke 116 multimeter has the ability to measure temperature (e.g., for thermocouples) and microamperage (uA), as well as voltage, capacitance, frequency and resistance.

## What does 200m amps mean?

The range switch on the front of the multimeter shows the maximum current that can be measured on that range. The range switch is pointing at the “200m” DC Amps range in the picture. This means that a display of “2.0” or “2,0” indicates a measured current of 2 milliamps, not 2 amps.

Who invented multimeter?

In 1920, a British Post Office engineer, Donald Macadie, is credited with inventing the very first multimeter. The story goes that he was frustrated that he needed to carry a bunch of different tools when working on telecom lines, so he created one tool that could measure amperes, volts, and ohms.

### How do you check if current is flowing?

To measure current, you must connect the two leads of the ammeter in the circuit so that the current flows through the ammeter. In other words, the ammeter must become a part of the circuit itself. The only way to measure the current flowing through a simple circuit is to insert your ammeter into the circuit.

### What does M mean on a multimeter?

The selection knob allows the user to set the multimeter to read different things such as milliamps (mA) of current, voltage (V) and resistance (Ω). Two probes are plugged into two of the ports on the front of the unit. COM stands for common and is almost always connected to Ground or ‘-‘ of a circuit.

What does 1 on a multimeter mean?
