Industrial equipment needs a reliable power supply to operate properly, use the dual input to obtain key power measurements. For single phase or 3-phase balanced systems, the dual inputs of the Industrial ScopeMeter® 120B Series can measure ac+dc rms voltage on channel A and ac+dc rms current on channel B. The Fluke 125B can then calculate; frequency, phase angle, active power (kW), reactive power (VA or var), power factor (PF) or displacement power factor (DPF) and can also calculate the power values for a 3-phase system where all phases have equal voltage and currents. This applies to...

Quickly step through recorded events to identify and troubleshoot intermittent faults. Fluke Connect mobile app compatibility Automated industrial machinery is harder than ever to trouble shoot. It’s not enough to just know where you have to test, you also have to know what to look for—and that can be hard without baseline measurement data or access to subject matter experts. The Fluke Connect® Assets wireless system of software and wireless test tools enables technicians to reduce maintenance costs and increase uptime with accurate equipment records and maintenance data that is easy to...
