橫河數(shù)字功率計(jì)WT310技術(shù)指標(biāo):
基本功率精度 (50/60 Hz):讀數(shù)的0.1% + 量程的0.1%
功率因數(shù)的影響:當(dāng)功率因數(shù) (λ)= 0 (S: 視在功率) 4 5 Hz ≤ f ≤ 66 Hz:S的±0.2%
頻率帶寬:DC, 0.5 Hz ~ 100 kHz (WT310H DC, 0.1 Hz to 20 kHz)
直接輸入電流量程:WT310: 12個量程/5 mA ~20 A
外部電流輸入:EX1:2.5/5/10[V] EX2:50m / 100m / 200m / 500m / 1 / 2[V](選件)
數(shù)據(jù)更新率:100m/250m/500m/1/2/5 s
