Fluke

Fluke calibrators are engineered to verify and calibrate a broad spectrum of electrical test instruments. For laboratory and metrology applications, the Fluke 5700A and Fluke 5720A serve as precision standards. Both models source DC voltage up to 1100 V and feature decade resistance configurations ranging from 1 Ω to 100 MΩ. \n\nFor broader, medium-accuracy workloads, the Fluke 5500A and Fluke 5520A support multi-product calibration. These units source AC/DC voltage and current, resistance, capacitance, and simulated power. The Fluke 5520A expands capability with a continuously variable resistance range up to 1100 MΩ and DC current sourcing up to 20.5 A. For AC voltage calibration, the Fluke 5790A functions as an automated AC measurement standard, operating across ranges from 2.2 mV to 1000 V with a frequency range of 10 Hz to 1 MHz.

For direct electrical measurements, Fluke provides both benchtop and portable options. The Fluke 45 is a 5-digit benchtop multimeter featuring a dual vacuum fluorescent display, standard RS-232 interface, and a DC voltage resolution down to 1 µV. For portable field testing, the compact Fluke 12 offers a 4000-count LCD with automatic AC/DC voltage selection up to 600 V.\n\nFor passive component characterization, the Fluke PM 6304/00n and Fluke PM 6306/02n benchtop RCL meters provide precise impedance measurements. The PM 6304/00n offers 204 selectable test frequencies from 50 Hz to 100 kHz. The PM 6306/02n offers a broader test frequency range of 50 Hz to 1 MHz with 3-digit resolution over 8,000 steps and a standard GPIB interface.

For analyzing complex electrical systems, the Fluke 4000 (Norma 4000) and Fluke 5000 (Norma 5000) are high-precision, modular power analyzers. The Norma 4000 supports 1 to 3 power phases, while the modular Norma 5000 accommodates 1 to 6 phases, facilitating parallel acquisition across all inputs. Both analyzers support torque and speed measurements via an optional process interface.\n\nFor portable waveform analysis, the Fluke 196C and Fluke 199C handheld ScopeMeters combine a digital oscilloscope with a digital multimeter. The 196C operates with a 100 MHz bandwidth and 1 GS/s sampling rate per channel, while the 199C provides a 200 MHz bandwidth and up to 2.5 GS/s real-time sampling. Both models feature isolated inputs rated up to 1000 V CAT II / 600 V CAT III.
