Data-logger for single-phase mains wiring for a quick and simple recording and analysis of the voltage quality. Quality parameters like effective mean value, transients, flicker and measurements up to 32nd harmonic are recorded by means of a user-defined averaging period from 3 s to 10 min. 6 mains adapters are enclosed with the set. https://elecena.pl/product/28019437/fluke-3030923-vr1710-mains-diagnostics-tester-1-phase-data-logger 2025-03-13 https://elecena.pl/product/28019437/fluke-3030923-vr1710-mains-diagnostics-tester-1-phase-data-logger 2025-09-19 https://elecena.pl/product/28019437/fluke-3030923-vr1710-mains-diagnostics-tester-1-phase-data-logger 2026-03-19 https://elecena.pl/product/28019437/fluke-3030923-vr1710-mains-diagnostics-tester-1-phase-data-logger 2026-04-12 https://elecena.pl/product/28019437/fluke-3030923-vr1710-mains-diagnostics-tester-1-phase-data-logger 2026-05-05 https://elecena.pl/product/28019437/fluke-3030923-vr1710-mains-diagnostics-tester-1-phase-data-logger 2026-05-27
