What Is the Purpose of a Digital Mini Multimeter?

Digital mini multimeters are multi-function devices used for purposes of troubleshooting and testing of electrical circuits, appliances and electronic components. The "digital" portion of the meter refers to the readout-type -- using numbers as opposed a needle indicator gauge used by analog counterparts. The "mini" in the descriptive name refers to the physical size of the meter, chosen by users for portability.
  1. Basic Functions of Digital Mini Multimeters

    • Digital Mini Multimeters are available in a number of different configurations based on model and stated industry use. All multimeters include basic settings and measurement parameters for testing AC and DC electrical current and voltage, resistance and capacitance of electronic circuitry components and continuity of electrical wires and continuous circuits.

    Industry-specific Digital Mini Multimeters

    • Industry-specific digital mini multimeters include special probes and settings for users requiring specialized measurements. HVAC (heating, ventilation and air conditioning) technicians require multimeters with a temperature probe and microamp function for measurement of flame sensors. Meters for specialty electronics and electrical technicians include more sensitivity and functionality of standard settings for specialized use in testing delicate circuitry or live voltage electrical circuits.

    Characteristics of Digital Mini Mutimeters

    • Compact size is the main characteristic of mini multimeters. Like full-sized meters, mini meters include inputs and outputs for electrical probes, battery operation, function control and sensitivity switches. Multimeters are either high- or low-impedance depending on the intended circuitry-type, with some models offering an impedance selector for dual usage. Digital readout allows more precise and easy-to-read numerical measurements than needle-type meters.

    Choosing Digital Multimeters

    • The choice of which digital multimeter is right for you is based on price and application. For hobbyists and professionals requiring general electrical and electric testing, a general purpose meter will provide adequate results. For specialists, a multimeter designed for work-specific use is required. Multimeters are available at different price-points, generally based on build quality and added features such as back-lit screens, weather and drop-resistance.
