This article introduces the features and characteristics of the F190 series universal oscilloscope launched by Fluke in 2000, including the isolation input function that enables it to have the overall application capability from field service to system development.
The F190 series ScopeMeter features fully isolated dual‑channel inputs, allowing safe simultaneous measurement of high‑voltage and low‑voltage signals. Its isolation safety level reaches Class II 1000 V and Class III 600 V, making it suitable for industrial environments where large voltage differences are common.
The instrument’s 2.5 GSa/s sampling rate and automatic trigger functions enable accurate analysis of motor drives, PWM inverters, and switching power supplies. With a current clamp accessory it can also measure active, reactive, and apparent power as well as power factor, supporting comprehensive diagnostics of power‑factor and system‑wide power distribution.
