Key Features of the Digital Multi meter
Unless you're taking your very first steps into the world of DIY electronics, you'll be familiar with basic multimeter functions such as voltage, current, continuity, resistance and so on. Here are 10 sophisticated features found on high-end and specialised units. See below for further advice on choosing a DMM.
1. Bluetooth® connectivity can offer easy data logging and advanced display functions.
2. Capacitance is calculated using an LCR multimeter (which also tests for inductance) by charging a capacitor with a known voltage. Make sure you safely discharge the capacitor before testing!
3. Clamp metering is a way of measuring the current flowing through a single wire or cable by clamping sensor jaws around the conductor, instead of touching it with a probe.
4. Dwell angle is measured by automotive multimeters, and refers to the proportion of time that the breakers in a car engine’s distributor are closed.
5. Environment sensing features are included in a multifunction unit that measures ambient light, sound level, temperature and humidity.
6. IP rating defines a multimeter's ingress protection (IP). For example, if your DMM is rated IP67, that means it can be immersed up to 1m deep without damage.
7. Measurement category is referred to as Cat I through Cat IV, and is a classification of what level of live voltage the multimeter is suitable for assessing.
8. Network cables can be tested using a combination multimeter which includes a remote terminator for checking cross-connect, continuity and other parameters of Ethernet cables.
9. Non-contact voltage detection shows you if there is live wiring near the unit, and is often used as a safety feature.
10. True RMS multimeters do the hard work for you. They have already calculated the average RMS voltage giving you the true value, regardless of whether the waveform is a pure sine wave or a more irregular shape.
