Top 4 best multimeter autoranging fluke

The Fluke 113 True-RMS Utility Multimeter is a digital multimeter (also known as a multitester) that measures AC/DC voltage to 600V, resistance to 60 kiloohms, and capacitance to 9,999 microfarads. The meter has a diode check for testing general-purpose germanium, silicon, and power diodes, and a continuity beeper which provides audible detection of resistance by turning on at less than 25 ohms and off at 250 ohms. It is also able to simultaneously check for voltage and continuity. This true RMS meter provides accurate readings when measuring linear or nonlinear loads where the current or voltage has a sinusoidal or nonsinusoidal waveform and has both manual- and auto-ranging capabilities for user flexibility. A Max/Min function records signal fluctuations and a hold function freezes measurements on the display. The 6000-count resolution, 3-1/2 digit digital display is backlit for readability in low-light conditions. The meter is safety rated for Category III to 600V and Category IV to 300V. It uses a 9V battery (installed) with a battery life of approximately 300 hours without backlight and has a sleep mode to maximize battery life. The meter measures 6.58 x 3.35 x 1.81 inches (H x W x D) and weighs 13 oz./404 g. (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.) This meter includes a holster with built-in probe holders for convenient storage.

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 voltage. Safety ratings are based on International Electrotechnical Commission (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.

The Fluke 28 II intrinsically-safe digital multimeter (also known as a multitester) is a true RMS, auto- and manual-ranging meter used in electrical testing applications to measure voltage, current, conductance, duty cycle, capacitance, frequency, and temperature, and perform resistance, continuity, and diode tests. This intrinsically safe meter is designed for use in Ex-rated areas, such as oil refineries, mines, and pharmaceutical plants. The meter is waterproof, dust-proof, and drop-proof, and is rated Ingress Protection certified IP67. A low-pass filter ensures accurate voltage and frequency measurements and percent of duty cycle measurements help diagnose variable-speed motor drives (VSDs) and switching power supplies. A capacitance range of 10,000 microfarads tests components and motor caps, and capacitance measurements perform high resistance and leakage tests. Data features include minimum, maximum, average, and peak capture to automatically record transients and measurement variations. Relative mode removes test lead interference on resistance measurements. An alarm sounds when the test leads are connected to the wrong jack for the measurement being taken. Backlit keypad buttons provide visibility in low lighting, and a reversible holster protects the display when not in use.

This true RMS (root mean square) insulation multimeter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has an undistorted waveform, or nonlinear loads, such as electronic devices or motors, where the current or voltage has a distorted waveform. 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 display has two-level bright white backlight for increased visibility and a 20,000-count resolution, meaning it can display up to 19,999 units in high-resolution mode (4-1/2 digit) before the operating range needs to be changed. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified Category III installations up to 1000V, 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), Category IV installations up to 600V, which covers equipment at the origin of the installation (such as electricity meters and primary over-current protection equipment), and Pollution Degree 2 for indoor use.

The Fluke 8845A/C benchtop digital multimeter (also known as a multitester) is a true RMS, auto-ranging meter for measuring current, voltage, resistance, frequency, and period in manufacturing and electrical testing and repair applications. The meter comes with a set of detachable test leads. The dual display shows two readings at once, such as voltage and resistance. The meter measures 2- and 4-wire resistance, and it has split-terminal jacks for measuring 4-wire resistance using only two leads (2 x 4 test leads sold separately), for improved accuracy. An audible continuity sensor confirms a circuit conducts electricity, and a diode test detects proper functioning of a circuits diodes. The meter's internal memory can store measurement and configuration data. The meter provides statistical information such as minimum, maximum, average reading, and standard deviation in numerical and graphical form for tracking measurement trends and sudden changes in readings. The user can set high and low limits for pass/fail testing. The meter can also express AC and DC voltage in decibels (dB), the power ratio of decibels to milliwatts (dBm), and percent of the reading relative to a preset reference value. The math mode manipulates readings according to the formula mx + b, where m and b are user-entered constants for scale factor and offset, respectively, and x is the actual reading as would be normally displayed. The relative mode stores a reading in memory to use as a zero point for subsequent readings so that multiple readings can be compared. The user has a choice of slow, medium, or fast measurement rate; the faster the rate, the less accurate the measurements. IEEE 488, RS-232, and Ethernet ports on the meter provide connection to a computer for data transfer and analysis and for remote operation (RS-232-to-USB cable, RS-232-to-USB cable adapter, and Fluke Forms software are included). Triggers can be set to respond to measurement, bus, front panel, and external inputs. A standby feature turns off the display and ensures the meter will not respond to front-panel, external, or remote command inputs. The meter has a removable handle that can be used to carry or prop up the meter during use. A certificate indicating compliance with International Standards Organization (ISO) and International Electrotechnical Commission (IEC) 17025 requirements for the competence of testing and calibration laboratories is included.

It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for Category I installations up to 1,000V (which covers protected electrical equipment such as small household appliances) and 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).
