电流表使用方法说明书
电流表使用方法说明书一、简介电流表是一种用于测量电流的仪器，广泛应用于电路测试、实验室研究和电工维修等领域。
本说明书将详细介绍电流表的使用方法，旨在帮助用户正确、安全、高效地操作电流表。
二、准备工作在使用电流表之前，请确保以下准备工作已完成：1. 检查电流表的外观是否完好，如有破损或松动应立即报修；2. 确保电流表的电源处于关闭状态；3. 验证待测电路的电压范围是否在电流表的测量范围之内；4. 准备适当的安全防护措施，如绝缘手套和护目镜。
三、测量步骤1. 连接电路a. 关闭待测电路的电源；b. 将电流表的正极（标有"+"符号）与电路的正极相连；c. 将电流表的负极（标有"-"符号）与电路的负极相连。
2. 选择量程根据待测电路的预估电流范围，选择电流表上与之相对应的最小量程。
若电流超过所选择的量程上限，应重新选择合适的量程。
3. 调节量程a. 将电流表的量程选择旋钮旋转到最高档位；b. 缓慢地将量程选择旋钮逆时针旋转，直到指针指向合适的量程刻度。
4. 打开电源打开待测电路的电源，使电流开始流动。
5. 读取测量值a. 观察指针位置，读取电流值；b. 如电流表采用数字显示，则直接读取显示屏上的数值。
6. 断开电路关闭待测电路的电源，并按照相反的顺序断开电流表与电路的连接。
四、注意事项在使用电流表时，请务必遵循以下注意事项，以确保测量准确、安全可靠：1. 选择合适的量程，避免电流超过电流表的测量范围，以免损坏仪器或导致人身伤害；2. 连接正确的电极极性，将电流表的正负极分别与电路的正负极相连；3. 在连接和断开电路时，确保电路电源已关闭，以免触电或损坏电路；4. 在读取测量值时，注意读数的准确性，并注意指针或显示屏上的小数点位置；5. 如发现电流表异常或测量值与预期不符，请停止使用并进行排查或咨询专业人士；6. 仔细阅读并遵守电流表的使用说明书，以免误操作。
五、维护保养为了保证电流表的正常使用和延长使用寿命，请定期进行以下维护保养：1. 清洁电流表的外观，定期擦拭并保持干燥；2. 避免电流表接触水和潮湿环境，以防止损坏电路板和内部元件；3. 当电流表不使用时，应存放在干燥、通风的地方，并远离化学品和易燃物品；4. 如发现电流表异常或故障，应及时送修或咨询专业人士。

安培表和伏特表的
3．电学实验中电路器材的选择 (1)基本原则 安全——不损坏实验仪器． 精确——尽可能减小实验误差． 方便——在保证实验正常进行的前提下， 选用的电路和器材便 于操作，读得的数据便于处理．
(2)实验器材的选取 ①电源允许的最大电流要大于电路中的实际电流． ②用电器的额定电流不能小于电路中的实际电流． ③电压表和电流表的量程不能小于被测电压和电流的最大值． ④根据被测电压和电流值的大小选择量程， 使指针偏转不超过 2 1 所选量程的 ，至少超过 .（如灯泡的额定电压时 6 伏特，那 3 3 么测量灯泡的电压表量程最好可以使 9 伏特）
RA Rx (2)临界值计算法：当内外接法相对误差相等时，有 ＝ ， Rx RV 所以 Rx＝ RARV为临界值．当 Rx＞ RARV(即 Rx 为大电阻)时 用内接法；当 Rx＜ RARV(即 Rx 为小电阻)时用外接法；Rx＝ RARV，内、外接法均可．
(3)实验试触法：按图 2210 接好电路，让电压表一根接线 P 先后与 a、b 处接触一下，如果电压表的示数有较大的变化(电 流表的分压作用明显)，而电流表的示数变化不大(电压表分流 作用不大)，则可采用电流表外接法；如果电流表的示数有较 大的变化， 而电压表的示数变化不大， 则可采用电流表内接法．
(3)滑动变阻器在电路中的两种接法 ①限流接法 如图 2212 所示，电路中变阻器起限流作用，负载 Rx 两端电 ERx 压的可调范围为 ～ E，在合上开关前使变阻器所使用的 Rx＋ R0 阻值最大， 因此在闭合开关前一定要检查滑动触头 P 是否在正 确的一端．
图 2212
②分压接法 如图 2213 所示，电路中变阻器起分压作用，滑片 自 A 端向 B 端滑动时，负载上电压的变化范围约为 0～ E.显然比限流时调节范围大．合上开关前滑片应 在 A 端， 以使负载 Rx 两端的电压和通过的电流最小．

直流电流表与交流电流表
直流电流表与交流电流表选自《中学教学实用全书物理卷》电流表是测量电流强度的电表．以安培为单位的，又叫安培表．1．直流安培表：直流安培表表头结构采用磁电式，它的外形如图（l）所示，内部线路如图（2）所示．原理：内部为内阻为的表头与多个电阻（如3个电阻r、及）组成环形电路，从不同接点抽头以区分不同量程，而不采用逐个与表头并联分流电阻的方法区分量程．这是因为采用环形电路使设计计算各电阻更准确一些，且对保护表头有好处．如图（2），采用r与串联，使总阻值便于各量程计算，而且r可起少许保护表头的作用．其余电阻可如下进行计算后选用：使用要点：l）检查指针是否在零位，如果指针偏离，应进行机械调零．2）估计被测电流的大小，选择适当量程．3）将电流表串接在被测电路中，并使电流从电流表的正接线柱流入．4）试触一下，以判断电流表是否接反及量程选择是否合适．5）测量应准确、迅速，测量后应及时切断电路．注意事项：1）由于电流表串接在电路中，使此电路电阻增加内阻造成测量值小于真实值．为了使测量值接近真实值，一般应选用内阻较小的电流表进行测量．由全电路欧姆定律知，而，其中R 为外电路电阻，为电源内阻，为电流表内阻．相对误差．若相对误差控制在2.5％以内，即，得到，这可以作为选择电表的依据之一．2）中学常用的直流安培表的准确度等级为2.5级，但有两种表示方法．只写数字2.5的，表示误差值不大于量限的2.5％．例如使用0.6A档，指针指在0.4A处，误差值不大于0.6A的2.5％即0.015A，这时相对误差为0.015／0.4＝3.8％．使用这种电表，应使用量程的2／3以上，否则相对误差较大．另一种标度方法是在级别数字外加圈，表示它的误差不超过指示值的2.5％，即相对误差总不超过2.5％。
3）若预先无法估计被测电流的大小，可将安培表串联一只可变电阻器接入被测电路中，且可变电阻器电阻用最大值，安培表用最大量程，接通电路后将可变电阻器阻值逐渐减小甚至减小到零，以判断应选量程．4）电流表使用完毕后，应存放在清洁干燥处，防止受潮，防止腐蚀性气体浸蚀，防止剧烈振动和撞击，避免强磁场影响．5）不允许直接将电流表接在电源两极上或在两极间触试。

--电流表指固定安装在电力、电信、电子设备面板上使用的仪表，用来测量交、直流电路中的电流[1]。
--在电路图中,电流表的符号为"圈A"[编辑本段]发展过程韦伯在电磁学上的贡献是多方面的。
为了德国物理学家韦伯进行研究，他发明了许多电磁仪器。
1841年发明了既可测量地磁强度又可测量电流强度的绝对电磁学单位的双线电流表；1846年发明了既可用来确定电流强度的电动力学单位又可用来测量交流电功率的电功率表；1853年发明了测量地磁强度垂直分量的地磁感应器。
韦伯在建立电学单位的绝对测量方面卓有成效。
他提出了电流强度、电量和电动势的绝对单位和测量方法；根据安培的电动力学公式提出了电流强度的电动力学单位；还提出了电阻的绝对单位。
韦伯与柯尔劳施合作测定了电量的电磁单位对静电单位的比值，发现这个比值等于3×108m/s，接近于光速。
[编辑本段]分类电流表是分为直流电流表和交流电流表。
直流电流表主要采用磁电系电表的测量机构。
一般可直直流电流表接测量微安或毫安数量级的电流，为测更大的电流，电流表应有并联电阻器（又称分流器）。
分流器的电阻值要使满量程电流通过时，电流表满偏转，即电流表指示达到最大。

安培(AndréMarie Ampè1775～1836年)
安培，法国物理学家，1825年提出了著 名的安培定律。他从1820年开始在测量电 流的磁效应中，发现两个载流导线可以相 互吸引又可以相互排斥。这一发现成为研 究电学的基本定律，为电动机的发明作了 理论上的准备。他对数学和化学也有贡献。

安培定则：用右手握螺线管，让四指指向螺线管中电流的方向，则大拇指 所指的那端就是螺线管的N极。
理解：
（1）将右手移至胸前（亦可放在桌面上）， 作握住螺线管状；
（2）让眼睛看见四指时，四指的指向与螺线管正面的绕线所标 的电流方向（即箭头方向）一致；

安培写给妻子的信
亲爱的朱丽：
昨天晚上六点，我削了萝卜的皮，又把南瓜洗干净，优雅地切成 几 片，再把南瓜、猪肉搅碎成一团，花了我很多的力气，准备要下锅时， 才想起炉子里没有火，我把木炭摆好，点了火，没想到怎么都点不着 木炭，我蹲下去，用力往炉口坎，结果弄得我一阵猛咳，等到咳嗽好 了，炉火又熄了，只好又点火，一边咳嗽一边吹火苗，火旺起来的时 候，我闻到焦味，原来忘了放油，锅子里的菜已经焦糊了。 亲爱的朱丽，你的丈夫就是在吞嚼这难吃的食物时，特别地想到你。 原来煮饭比物理难，让我精疲又力竭，现在你知道，为什么我一天只 吃两餐的原因了吧!

• 在电池上常见的单位为 mAH （毫安•小时），例 如500mAH 代表这颗电池能够提供 500mA×1hr = 1800C(库仑)的电子，亦即提供一耗电量为 500mA 的电器使用一小时的电量 。

一次，安培正慢慢地向他任教的学校走 去，边走边思索着一个电学问题。经过 塞纳河的时候，他随手拣起一块鹅卵石 装进口袋。过一会儿，又从口袋里掏出 来扔到河里。到学校后，他走进教室， 习惯地掏怀表看时间，拿出来的却是一 块鹅卵石。原来，怀表已被扔进了塞纳 河
安培
安培安培（Andre－Marie Ampere，1775～1836）法国物理学家。
1775年1月22日生于里昂一个富商家庭。
从小受到良好的家庭教育。
他父亲按照卢梭的教育思想，鼓励他走自学成才之路。
12岁时就自学了微分运算和各种数学书籍，显示出较高的数学天赋。
为了能到里昂图书馆去看接阅读欧勒、伯努利等人的拉丁文原著，他还花了几星期时间掌握了拉丁文。
14岁时就钻研了当时狄德罗和达兰贝尔编的《百科全书》。
没有上过任何学校，依靠自学，他掌握了各方面的知识。
1793年（18岁）因其父在法国大革命时期被杀，为了糊口他做了家庭教师。
在读了一本卢梭关于植物学的书以后，又重新燃起了他对科学的热情。
1802年，在布尔让－布雷斯中央学校任物理学及化学教授，1808年被任命为新建的大学联合组织的总监事，此后一直担任此职。
1814年被选为帝国学院数学部成员。
1819年主持巴黎大学哲学讲座。
1824年任法兰西学院实验物理学教授，1836年6月10日在马赛逝世。
他的兴趣十分广泛，早年是在数学方面，曾研究过概率论及偏微分方程，他的一篇关于博奕机遇的数学论文曾引起达朗贝尔的瞩目。
后来又作了些化学研究，他只比阿伏加德罗晚三年导出阿伏加德罗定律。
由于他高超的数学造诣，他成为将数学分析应用于分子物理学方面的先驱。
他的研究领域还涉及植物学、光学、心理学、伦理学、哲学、科学分类学等方面。
他写出了《人类知识自然分类的分析说明》（1834～1843）这一涉及各科知识的综合性著作。
他的主要科学工作是在电磁学上。
1820年奥斯特发现电流磁效应的消息由阿拉果带回巴黎，他作出迅速反应，在短短的一个多月时间内，提出了3篇论文，报告他的实验研究结果：通电螺线管与磁体相似；两个平行长直载流导线之间存在相互作用。
进而他用实验证明，在地球磁场中，通电螺线管犹如小磁针样取向。
一系列实验结果，提供给他一个重大线索：磁铁的磁性，是由闭合电流产生的。
起先，他认为磁体中存在着一个大的环形电流，后来经好友菲涅耳提醒（宏观圆形电流会引起磁体中发热），提出分子电流假说。
