Amprobe PM55A Pocket Multimeter with Non-Contact Voltage Detection by Amprobe 
The Amprobe PM55A digital multimeter with built-in non-contact voltage detector is an average-sensing, auto-ranging meter for measuring voltage, resistance, capacitance, frequency, and microcurrent in electrical testing applications. The attached test leads measure alternating current (AC) voltage and direct current (DC) voltage to 600 volts (V), resistance to 6 megaohms, capacitance to 2,000 microfarads, frequency to 30 kilohertz (kHz), and microcurrent to 2,000 microamp. The meter has a non-contact voltage detector that senses AC voltage without touching or interrupting the circuit. The meter measures 4.4 x 2.1 x 0.4 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; and D is depth, the horizontal distance from front to back), and it can be carried in a shirt pocket when not in use. The microamp reading identifies current changes in flame detector applications. The meter automatically selects AC voltage, DC voltage, or resistance function based on input. An audible continuity sensor confirms that the circuit conducts electricity, and a diode test detects whether the circuit's diodes work properly. An auto power-off mode turns off the unit after 10 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced.
This average sensing, or average responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It is an auto-ranging meter and automatically selects the correct operating range for the property being measured. The meter has a 6,000-count (3-5/6 digit) liquid crystal display (LCD) that can display up to 5,999 units before the operating range needs to be changed. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category II installations up to 600V (which covers large household appliances and devices connected to a fixed power supply, such as refrigerators and air conditioners), and category III installations up to 300V (which covers items used with enclosed building circuit installations, such as service panel parts, branch circuits, and fixed installations that are connected directly to a building's AC power supply). It comes with a silicone holster and a soft, zippered carrying case.

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltages. Safety ratings are based on the International Electrotechnical Commission's (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.
