Any electrical or broadcast engineer, or anyone who works on electrical devices for that matter, should know what a digital multimeter, or DMM is.
These handy devices are used to measure the three basic parameters of electricity – current (amps), voltage (volts) and resistance (ohms).
Here are a few little insights into how accurate readings are obtained with a DMM…
- Voltage – Probes from the DMM are placed across the points where you’re measuring voltage.
