概述 C31型直流电表是磁电系张丝支承指针指示可携式电表,仪表具有良好的*颠震性能和较高的灵敏度及使用寿命.C31型仪表为多量限仪表,量限转换采用插塞,使用方便.可供工厂,学校或科研部门的实验室作精密电气实验用或在计量室作标准表使用. General Model C31 DC meters are portable taut-band suspended moving coil instruments with pointerindication.The meters feature good anti-shock,higher sensitivity and long durabiity. Model C31 Meters are multirange instruments and a plug-in t*e switch is used for rangechange-over,so for the sake of easy operation.The meters can be used for precise electric testin the laboratories of factories,schools or scientific reserch departments,or as standard meters in electrical measuring departments. 仪表的测量范围与消耗:Measuring Ranges and Consumption Model 型号 | Measuring ranges 测量范围 | Interal Resistance Or Voltage Drop 内阻或压降 | Internal Resistance Or Consumed Current 内阻或消耗电流 | Scale Division 刻度分格 | C31-UA | 0-10μA 0-20μA 0-50μA 100/200/500/1000μA 150/300/750/1500μA | R≈10KΩ R≈2。6KΩ R≈600Ω R：1200-1100-560-300Ω R：933-633-292-153Ω | ───── | 100 100 100 100 150 | C31-mA | 1.5/3/7.5/15mA 5/10/20/50mA 100/200/500/1000mA | U:10-20mV U:12-28mV U:45mV | ───── | 150 100 100 | C31-A | 7.5/15/30/75/150/300/ 750mA/1.5/3/7.5/15/30A 2/5/10/20A | U:27-45mV U≈45mV | | 150 100 | C31-mV | 0-10mV 45/75/150/300/750/1500/3000mV 100/200/500/1000Mv 0-75mV/A | ───── | R≈5Ω 45mV R≈15Ω 75mV R≈30Ω 150-300mV I=2mA I=1mA I=1mA | 100 150 100 150 | C31-V | 0.045/0.075/3/7.5/15/30 75/150/300/600V 1.5/15/150/1500V 2/5/10/20V 50/100/200/500V | ───── | 45mV R 75mV R 3-600V I=2mA I=2mA I=2mA I=1mA | 150 150 100 100 | C31-Av | 1.5/3/7.5/15/30A3/15/30 /75/150/300/600V | 1.5-30A V≈45mV | 3-600V I=5mA | 150 |
