By the term “tool” we mean any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Informally the word is also used to describe a procedure or process with a specific purpose.
A very big part of electrical calibration procedures consists of DC and Low Frequency (LF) measurements. Multimeters, resistors, power supplies and electrical testers are commonly used instruments that require periodical calibration. Voltage, current, resistance, inductance, capacitance, time and frequency are the principal quantities regarding DC and LF measurements. The Volt (V), the Ohm (Ω) and […]
