The Fluke 8846A is a 6.5 digit precision bench multimeter designed for test, research and development, and service applications where measurement accuracy and versatility are both required. The instrument is presented in the datasheet as part of the Fluke Bench Multimeters family alongside the 8845A (35 ppm) and the 5.5 digit 8808A, with the 8846A representing the 24 ppm precision tier and adding a USB memory drive port for data transfer.
Applications listed in the datasheet include manufacturing test, research and development, and service work. The 8846A is documented as suitable both for bench use and for integration into automated test systems, with front and rear inputs to simplify connections when rack-mounted. The datasheet specifically highlights use cases such as analyzing analog circuit drift and intermittent events via TrendPlot, revealing stability or noise problems with the Histogram mode, and performing sensitive low-current and low-ohms measurements on modern surface-mount assemblies.
ValueTronics has supported test and measurement professionals since 1992 and stocks the Fluke 8846A alongside the broader Fluke Bench Multimeter family. Every unit is processed through our 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where instruments are inventoried, inspected, and prepared for shipment by our technical team. Working with ValueTronics gives buyers access to both new authorized Fluke equipment and a substantial inventory of pre-owned and refurbished bench DMMs from a single source.
Fluke Corporation was founded by John Fluke Sr. in 1948 and has been part of the Danaher Corporation portfolio since 1998, with Fluke's parent organization later spun off as Fortive Corporation in 2016. The Fluke brand has remained the primary identity for the company's precision bench and handheld measurement instruments throughout these corporate transitions.
The Fluke Bench Multimeter family covered on this datasheet comprises three models: the 5.5 digit 8808A, and the 6.5 digit 8845A and 8846A. All three share a common form factor (88 mm x 217 mm x 297 mm, 3.6 kg for the 6.5 digit models and 2.1 kg for the 8808A), the 2x4-wire ohms measurement technique with patented split terminal jacks, dual display, and the FlukeView Forms Basic software package.
The 8808A is positioned in the datasheet for manufacturing, development, and service applications, while the 8845A and 8846A are presented as precision multimeters for bench or automated test system use. Within the 6.5 digit tier, the 8845A and 8846A share the same core measurement specifications; the 8846A adds capacitance measurement, RTD temperature measurement, a real-time clock, and a USB memory drive port for data transfer.
Each new model in this family is listed as its own dedicated product page with condition-matched pricing and availability. Use the links in the comparison table to reach the specific model and configuration that matches your application.
Within the family, the 8846A is differentiated by its capacitance and RTD temperature functions, its USB memory drive port, and its real-time clock, none of which appear on the 8845A or 8808A per the datasheet's summary specifications. The 8846A also carries the family's tightest basic V dc accuracy at 0.0024% + 0.0005%.
The principal differences across the family are resolution and accuracy tier, measurement function breadth, and interface set. The 8808A provides 5.5 digit resolution with 0.015% + 0.003% basic V dc accuracy, RS-232 with optional USB adapter, and simplified ASCII or Fluke 45 programming. The 8845A and 8846A both provide 6.5 digit resolution, RS-232, IEEE-488.2, and Ethernet interfaces as standard, and SCPI programming with Agilent 34401A and Fluke 45 emulation.
The comparison table below lists the headline specifications side by side so the differences in voltage accuracy, current and resistance range, and supported measurement functions (capacitance, temperature, real-time clock, USB memory port) can be reviewed at a glance against the datasheet's published values.
