for resistance, measuring from ohms to megaohms.for voltage, both AC and DC, measuring from millivolts to hundreds of volts.for current, both alternating (AC) and direct (DC), measuring from micro- or milli-amps to amps.On a multimeter you will find several settings available to test for different areas. When a circuit or device malfunctions, testing for continuity (i.e., is the circuit continuous from source to sensor and back) and measuring voltage/current/resistance can help locate and identify problems. A multimeter is crucial for troubleshooting.
Multimeters can measure voltage, current, resistance, and continuity, thus the name: multi-meter.

What is a Multimeter?Ī multimeter is an electrical instrument that is used to test circuits. After all, we’ve got a sensor to troubleshoot. Don’t worry, we will walk you through how to use a multimeter to troubleshoot your industrial sensor and get it working properly in no time!īut wait - what is a multimeter and how does it work? Let’s take a quick look. One easy way to figure out what’s wrong is using a multimeter to test your sensor. Maybe it only works occasionally, maybe there’s too much noise to establish a strong connection, or maybe you just don’t know what is wrong.
