B&K Precision Model 2831E, 4 Digit True RMS Bench MultimeterB&K Precision model 2831E is a versatile and dependable bench-top digital multimeter. It takes typical multimeter measurements such as volts, ohms and amps with great accuracy and stability. Readings can be taken at a maximum rate of 25 readings/sec with measurement rates selectable between slow, medium, and fast. This instrument is suitable for applications in education, service and repair and manufacturing requiring basic and reliable measurements. The 2831E has excellent quality, good resolution making it an essential part of the test bench.This multimeter has built-in math functions not found in other bench meters in this price category. The 2831E is an attractive choice for cost-conscious users requiring a basic and dependable meter with a broad range of extra features offered at a value price. Another feature is the ability to perform two measurements at once, for example Volts AC and DC or Volts AC and frequency.The LCD has a 20,000-count resolution, meaning it can display up to 19,999 units (4 1/2 digits) before the operating range needs to be changed. 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). Also Category II installations up to 300V (which covers large household appliances and devices connected to a fixed power supply, such as refrigerators and air conditioners).Features and Benefits:Up to 20,000 Count display resolution4 1/2 Digit Duel LED Display for clear reading in the darkest environmentBasic VDC accuracy of up to 0.03%Dual display to indicate two measurements simultaneouslyAC + DC True RMS for accurate interpretation of any waveform signalUp to 25 readings per second measurement rateAC volt and amp measurement over wide frequency range (ACV 100 kHz/ACI 20 kHz)Limit mode for Pass/Fail testingBuilt-in math functions: Rel; Max/Min; dBm; dB; %; Hold; CompareCATI (1000 V)/CATII (300 V) ProtectionUSB (Virtual Com)SCPI compatibleIncrease Productivity with PC Connectivity and Math FunctionsThe built-in math operations Rel, Max/Min, dBm, dB, Percent (%), and Hold enhance your productivity and provide educators with a convenient tool to teach basic math concepts.The 2831E is programmable via USB interface using industry standard SCPI commands. You can control and configure the instrument from a remote PC and retrieve measurement results for further analysis.Limit OperationThe 2831E’s limit operation lets you set and control the values that determine a HI / IN / LO status of subsequent measurements. The meter can be configured to emit an audible alarm when readings are outside of the configured limit.ApplicationsService and repairManufacturingEducationalTest & measurement fields that require basic measurementsSupplied withTest leads, power cord, spare fuse, operating manual , calibration certificate and test report
