Simple handheld multimeters often have two inputs for DC current measurements. One input is usually for ranges up to 200mA and the other is for high currents up to 10A or 20A. There is no 2000mA range. So if you need to measure currents in the order of 250mA, you need to use the 20A range, which offers limited
Power quality events are a common occurrence in industrial facilities and standard “industrial” power supplies typically provide a level of immunity to these events. The most common events are voltage sags (nearly 50%) followed by voltage transients and short duration overvoltage events or “swells”
