Funit is 1KHz When the L-FILTER sets as ON: 45Hz~66Hz frequency range allowable error-0.03 %~-0.05 of reading
When the AC is measured, if the fundamental frequency exceeds 200Hz, the F-Filter is required to be turned off in order to measure the most accurate value **When the frequency range is more than 10KHz, the 7120 starts to support
