Readings
V rms actual, A rms actual (cycle by cycle calculation).....±(2 % + 10 counts)
V rms max, A rms max......................................................±(2 % + 10 counts)
V rms min, A rms min........................................................±(2 % + 10 counts)
Cursor Readings
V rms max, A rms max......................................................±(2 % + 12 counts)
V rms average, A rms average..........................................±(2 % + 10 counts)
V rms min, A rms min........................................................±(2 % + 12 counts)
