※ For industry and laboratory application only
► TH3300 is a reference-level three-phase power/energy measurement standard instrument.
► The instrument uses the world's top devices and advanced measurement self-calibration technologies to ensure that the annual change rate of standard measurement is less than U:20 ppm @ 30 V ~ 480 V; I: 30 ppm @ 50 mA～120 A; P/E: 50 ppm @ (30 V～480 V, 50 mA～120 A).
► This instrument can meet the test requirements for electric energy measurement under dynamic waveform conditions such as broadband and complex harmonics and under low current conditions, and solves the traceability problem of R46 electric energy measurement.
► Power supply: AC (220 ± 22) V, (50 ± 2) Hz; maximum power consumption: 120 VA
► Working environment: 18℃～28℃, 20%～85% R H, non-condensing
► Storage environment: 0℃～40℃, < 95% R H, non-condensing
► Communication interface: RS232, USB, LAN
