FUNCTIONS
Energy loss calculator: classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint true system energy losses in dollars (other local currencies available).
Power inverter efficiency: simultaneously measure AC output power for power electronics systems.
Power wave data capture: GF438II analyzers capture fast RMS data, show half-cycle and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.).
Waveform capture: GF438II capture 50/60 cycles (50/60Hz) of each event that is detected in all modes, without set-up
Automatic transient GF438II analyzers capture 200 kHz waveform data on all phases simultaneously up to 1000V.
Fully class-A compliant: GF438II analyzers conduct tests according to the stringent international IEC 61000-4-30 class-A standard.
Mains signaling: GF438II analyzer measure interference from ripple control signals at specific frequencies.
Troubleshoot: analyze the trends using the cursors and zoom tools.
Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance.
Measure all three phases and neutral: with included four flexible current probes with enhanced thin flex designed to fit into the tightest places.
Automatic trending: every measurement is always automatically recorded, without any set-up.
System-monitor: ten power quality parameters on one screen according to EN50160 power quality standard
Logger function: configure for any test condition with memory for up to 600 parameters at user defined intervals.
View graphs and generate reports: with included analysis software.
Battery life: up to 5 hours operating time per charge on Li-ion battery pack.
