Fluke / Wavetek 1361 4.5 to 6.5 Digit Multimeter

The Fluke/Wavetek 1361 is a VXI-based 6.5-digit digital multimeter engineered for high-precision automated measurements in test systems. This single-width C-size VXI module delivers programmable resolution from 4.5 to 6.5 digits with read rates up to 1000 readings per second, making it suitable for rapid characterization and production testing. Core measurement functions include DC voltage, AC voltage to 1000 Vrms, and resistance, with optional DC and AC current modules rated to 2 amperes. An internal data store buffers 1 to 1000 readings for continuous high-speed acquisition independent of system controller bandwidth.
