The Amprobe AM-530 digital multimeter with included temperature probe and built-in non-contact voltage detector is a true RMS (root mean square) sensing, auto- or manual-ranging meter for measuring current, voltage, resistance, capacitance, frequency, and microcurrent in commercial electrical testing applications. The meter comes with a set of detachable test leads that measure alternating current (AC) and direct current (DC) to 10 amp, AC voltage to 750 volts (V), DC voltage to 1,000 volts (V), resistance to 40 megaohms, capacitance to 4,000 microfarads, frequency to 10 megahertz (MHz), and microcurrent to 4,000 amp. The meter comes with a K-type thermocouple probe for measuring temperature. The meter"s non-contact voltage detector senses AC voltage without making contact with the circuit. A built-in flashlight illuminates dark areas of the work environment. The microamp reading identifies current changes in flame detector applications. The 4,000 microfarad capacitance rating is for testing run/start capacitors on motors. A liquid crystal display (LCD) shows readings both in digits and on a 41-segment bar graph. The display is backlit for visibility in low light. The relative zero mode stores a reading in memory to use as a zero point for subsequent readings, allowing for quick comparison of readings. The maximum or minimum reading mode displays the highest or lowest reading in a session to track a sudden increase or decrease in readings. The hold function keeps a reading on the display, even after the meter is disconnected. 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 15 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter"s batteries need to be replaced. The back of the meter has a tilt stand that allows the meter to be propped on a surface for hands-free use. A probe holder on the body of the meter stores probes when not in use. The meter comes with a Velcro strap for hanging.This true RMS (root mean square) sensing 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, or non-linear loads, such as electronic devices or motors, where the current or voltage has a sinusoidal non-sinusoidal waveform. Two ranging modes (auto or manual) offer a range of operator control when taking readings. When turned on, the meter is in auto-ranging mode and automatically selects the correct operating range for the property being measured. It can be switched to manual-ranging mode, which allows the operator to choose the appropriate operating range. The meter has a 4,000-count (3-3/4 digit) liquid crystal display (LCD) that can display up to 3,999 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 1,000V (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 600V (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).SpecificationsMaximum alternating current (AC) input10 ampMaximum direct current (DC) input10 ampMaximum AC voltage input750 volts (V)Maximum DC voltage input1,000VMaximum resistance detected40 megaohmsMaximum capacitance detected4,000 microfaradsMaximum frequency detected10 megahertz (MHz)Maximum AC microcurrent4,000 microampMaximum DC microcurrent4,000 microampNon-contact AC voltage detection range90 to 600VTemperature measurement range-40 to 1832 degrees Fahrenheit (F)/-40 to 1,000 degrees Celsius (C)Power supply9V 6F22 or NEDA1604 battery (one, installed)Fuses0.5 amp/1,000V ceramic fast-blow fuse (one, installed) and 11 amp/1,000V ceramic fast-blow fuse (one, installed)Standards metEuropean Conformity (CE); International Electrotechnical Commission (IEC) and European Normal (EN) safety standard 61010-1; N10140 Australia; Canadian Standards Association (CSA)Weight0.78 lb./354 gMeter dimensions7.2 x 3.5 x 1.8 inches/182 × 90 × 45 mm (H x W x D) H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.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.Amprobe manufactures electrical testing equipment for commercial, industrial, and home use.
