The Fluke 1735 3-Phase Power Logger is a test instrument utilized by electricians to conduct energy studies and basic quality logging, providing a 10.24 kHz sample rate and a 50 Hz or 60 Hz line frequency. Fluke 1735 quality meters detect key three-phase parameters like rms voltage, rms current and phase angle, which can be essential in detecting elusive power anomalies. Technicians can set up the Fluke 1735 in mere seconds. The four current probes are then connected with one plug, and the instrument automatically detects, scales and powers the probes. Set your current probes to 15 A, 150 A, or 3000 A for high accuracy in nearly any application.
