7110-10K-HARM

7120-100K-HARM

500Hz -3db 基於Butterworth 之數位濾波器

50Hz -0.03% reading， 60Hz -0.05% reading

F單位為 1KHz

當L-FILTER 設定ON:  45Hz~66Hz頻段容許誤差-0.03 %~-0.05 of reading

AC量測時基頻頻率超過200Hz時需將F-Filter關掉以量得準確讀值

**超過 10KHz 以上頻段7120才有支援

AC power ranges (Auto or Manual)(40 ranges)範圍up to 16KW
大Power(W)值依電壓檔位蕞高量程而定

DC ±0.2% reading ± 0.5% of range

15 Hz≦f

45 Hz≦f≦66 Hz ±(0.1% of reading + 0.1 % of range)

66 Hz<f≦1 kHz ±(0.2% of reading + 0.2 % of range)

1 kHz<f≦10 kHz ±(0.4% of reading + 0.3 % of range)± [% of reading]

10 kHz<f≦100 kHz ±(0.5 % of reading + 0.5 % of range)±[% of reading]

頻率介於45 to 66 Hz: Add 0.3% of reading.
頻率於45 to 66 Hz:範圍以外 Add 1% of reading

當功率因素PF 為0時,Watt的誤差範圍為

情況1: for 45 Hz<f

情況2: for 45 Hz>f 或 f >66 Hz

Add ±{(3.5 + 0.5 × f)% of VA} for up to 100 kHz as reference data

The unit for frequency f is kHz.

當功率因素0 < PF ≦ 誤差範圍

When 0<PF≦1 (θ: phase angle of the voltage and current)

for 45 Hz≦f≦66 Hz. Add ± power reading *%

for f < 45 Hz, f >66 Hz. Add ± power reading *{ tanθ* (0.5×f+0.2) }%
