Ｄ５２－Ｗ型０．５级电动系低功率因数瓦特表，供直流电路或交流４５－６５－５００ＨＺ低功率因数电路中测量功率．也可以用在任一功率因数（被测量不大于仪表上的量限的条件下）的电路中测量功率．仪表采用张丝支承和多反射光标指示，故灵敏度很高，仪表的本身消耗很低．在一般测量时，仪表本身消耗可忽略不计，该型仪表特别适用于小功率电器，如家用电光源的功率，或测量微型电机变压器的空载损耗．仪表测量范围与消耗：仪表型号测 量 范 围额定电流(A) 额定电压(V) 满量程功率值(W)电压回路电流值D52-W0.025/0.05 0.075/0.15/0.18750.0375/0.75/1.5/30.1/0.2 0.3/0.6/0.75/1.5/3/6/120.25/0.5 0.75/1.5/1.875/3.75/7.5/15/300.5/1 30/75/150/300/600 1.5/3/3.75/7.5/15/30/601/2 3/6/7.5/15/30/60/1202.5/5 7.5/15/18.75/37.5/75/150/3005/10 15/30/37.5/75/150/300/600────────────────────────────────────────0.025/0.05 0.075/0.1125/0.15/0.187/5/0.225/0.375/0.75/1.50.1/0.2 0.3/0.45/0.6/0.75/0.9/2.5/3/60.25/0.5 0.75/1.125/1.5/1.875/2.25/3.75/7.5/150.5/1 1.5/2.25/3/3.75/4.5/7.5/15/301/2 30/45/75/150/300 3/4.5/6/7.5/9/15/30/602.5/5 7.5/11.25/15/18.75/22.5/37.5/75/1505/10 15/22.5/30/37.5/45/75/150/300
