1. vc921万用表怎测电容
空调是现代生活中不可缺少的一部分，它提高了人们的生活水平，使人们在适宜的温度下生活。但是做为家用电器，长时间的使用，也难免会出现故障，那么出现故障该怎么办呢？本文就教教大家怎么处理。
空调基础知识
核心部件
空调器的制冷（制热）系统由压缩机、冷凝器、毛细管（或电子膨胀阀）、蒸发器四大部分组成。分体式空调器中，这4大部件分为室内机和室外机两部分。室外机有压缩机、冷凝器、毛细管（或电子膨胀阀）3大制冷（制热）部件，室内机只有1只蒸发器，它们之间用管路、截止阀来连接，从而成为一个完整的制冷（制热)系统。
压缩机
将气体压缩，将低压气体变成高压气体，常见的有涡旋式压缩机、转子式压缩机，为制冷剂提供从高温环境吸热、向高温环境放热的能量，帮助制冷剂循环顺利进行。
冷凝器
将制冷剂由气体冷凝变成液体，放出热量。
节流装置
将高压液体变成低温低压液体，常见的有毛细管和膨胀阀，制冷剂压力越低，沸点越低，节流装置的作用就是将制冷剂的压力降低到制冷剂对应的沸点比制冷时室内温度（需要从室内吸热），制热时的室外温度低（需要从室外吸热），保证制冷剂能从空气吸热，正常蒸发。
蒸发器
将制冷剂由液体蒸发变成气体，吸收热量。
循环原理：
制冷和制热原理
制冷
空调制冷时，制冷剂先经过压缩机变成高压气体；然后经过室外机换热器（冷凝器）冷凝放热变成高压液体；然后高压液体经过节流装置，会变成低温低压的液体；然后经过室内机换热器（蒸发器）蒸发吸热变成低温低压的气体，最后再回到压缩机。
制热
空调制热时，制冷剂先经过压缩机变成高压气体，然后会先经过室内机换热器（冷凝器）冷凝放热变成高压液体；然后高压液体经过节流装置，会变成低温低压的液体；然后经过室外机换热器（蒸发器）蒸发吸热变成低温低压的气体，最后再回到压缩机。
注意制冷制热时，制冷剂流向是不同的，制冷时先流过室外机换热器，此时室外机是冷凝器，室内机是蒸发器；制热时，制冷剂先流过室内机换热器，此时室内机是冷凝器，室外机是蒸发器。制冷制热不同状态时，空调会通过四通阀改变制冷剂的流向。上图红色方框内为四通阀。如果没有四通阀，空调只能实现单一制冷或者制热，不能冷热切换。
检修思路
空调检修遵循由室内到室外再到中间，先易后难。要想电路故障检修具体和简单化，就要在检修时把室内与室外电路、主电路与控制电路故障区别开来。
控制与主电路故障
1、对于压缩机频繁开停故障，可通过测量空调器负载电压与压缩机运行电流来判断故障部位。如压缩机运转电流过大，说明故障在主电路；如压缩机运转电流正常，说明故障在控制电路。
2、对于风机运转压缩机不启动故障，可通过观察室外交流接触器是否吸合来判定故障部位。如接触器吸合而压缩机不工作，说明故障在主电路；如接触器不吸合，说明故障在控制电路。对于变频空调压机不启动，可通过检测功率模块来排除故障。
3、测量室内与室外保护元件是否正常，来判断故障区域。如测量保护元件正常，说明故障在控制电路；如测量保护元件损坏，说明故障在主电路。
4、对于压缩机不运转故障，还可通过强行按动接触器，观察压缩机是否能正常制冷。如按下接触器后压缩机能运转且制冷，说明故障在控制电路；如按下接触器压缩机过流或不启动，说明故障在主电路。(变频压缩机不能采用此法)
5、对于压缩机频繁启动故障，如摸压缩机外壳温度过高，多为主电路或压缩机本身故障。
6、对于变频空调来说，可以通过空调器的故障指示灯来进行判断，如功率模块、通讯故障等。
室内与室外电路故障
1、有输入与输出信号线的空调器，可以使用短接方法来进行判断。如采用上述方法后空调器能恢复正常，说明故障在室外机；如故障没有消除，说明故障在室内机。
2、测量室外机接线端上有无交流或直流电压判断故障部位。如测量室外接线端子上有交流或直流电压，说明故障在室外机；如测量无交流或直流电压，说明故障在室内电路。
3、对功率较大的柜式空调器可通过观察室外接触器是否吸合，来判断故障部位。如接触器吸合，说明故障在室外机；如没有吸合，说明故障在室内机。
4、对于有故障显示的空调器可通过观察室内与室外故障代码来区分故障部位。
5、对于采用串行通讯的空调器电路，可用示波器测量信号线的波形来判断故障部位。
6、对于热泵型空调器不除霜或除霜频繁，则多为室外主控电路板故障。
7、有条件也可通过更换电路板来区分室外机故障。
空调故障检修方法
1、插上电源插头，室内机电源指示灯亮，如无电源指示，说明您家的电源有故障或指示灯损坏。（下图左起第一个为电源指示灯）
2、有电源指示，用遥控器按操作键，信号发射不出去。首先，检查遥控器内的电池是否有电，然后检查电池的正负极片触点有无氧化腐蚀，若上述正常，检查遥控器内部电路板是否损坏，可将遥控器靠近一台调幅收音机，按遥控器键进行干扰试验，听收音机是否发出有“嘟嘟”声，有声说明遥控器无故障。
3、当遥控器确定无故障时，信号还是发射不出去时，可用室内机强制运行开关验证，强制运行时，室内贯流风机和室外压缩机若运转正常，制冷效果良好，则证明空调器室内机红外接收部位有故障。
4、当你使用的遥控器装上新电池使用不到一个月就不显示时，可将遥控器的后盖打开，用95%的酒精清洗一下电路板和按键触点面导电胶片，干燥后，即可排除漏电故障，遥控器液晶显示缺字也可采用这种方法。
5、变频空调器中的温度传感器起着非常重要的作用，室内机有空气温度传感器和蒸发器温度传感器;室外机有空气温度传感器，高压管路传感器和低压管路传感器，有的传感器在长期使用后发生阻值变化，使控制特性改变，(如室内机空气温度传感器阻值变大后，会引起变频器输出频率偏低)，为了保证控制精度，及其相同的工作特性，确定传感器故障后，应换用原型号的产品。
6、在空调器出现故障时，如果鉴别整个控制系统是否有故障，可将室内机控制器上的开关放在“试运行”挡上，此时微处理器会向变频器发出一个频率为50Hz的信号。若此时空调器能运转，并保持频率不变工作，一般认为整个控制系统无大问题，可着重检查各传感器是否完好。如果空调器不能正常运行，说明控制系统有故障。
故障情况分析
常规故障现象成因
故障一
现象：空调系统不工作且空调的压缩机不吸合。
成因：制冷剂部分或全部泄露。
维修：找出导致制冷剂泄漏的故障点，并更换损坏的零件，然后重新将其抽成真空状态，再添加适量的制冷剂。容易发生制冷剂泄漏的部位有：管路及其密封圈、冷凝管、膨胀阀、压力开关等。
故障二
现象：空调不能制冷，压缩机能够吸合，但低压很低且排出管表面温度极高。
成因：膨胀阀上的感温头损坏，导致冷媒泄漏无法制冷。
维修：将坏掉的感温头换掉，并将系统抽成真空、保压，然后根据空调规定的剂量适量添加制冷剂。
故障三
现象：空调系统不工作且空调的压缩机不吸合，但空调系统内的压力平衡。
成因：空调系统的保险片、继电器、热敏电阻接线、冷凝风扇接线等部件出现问题。
维修：对上述部件一一进行排拆，更换掉损坏的的部件。
故障四
现象：制冷效果不佳，风量较小，且机箱运行噪声较大。
成因：空调的管道中有异物进入，或者灰尘堆积导致过滤网阻塞。
维修：定期拆下过滤网并对过滤网进行清洗，清洁管道，然后重新安装。
故障五
现象：空调制冷效果不佳，机箱正常运行但高、低压的压力均过高。
成因：添加了过量的制冷剂，或在压缩机中添加了过多的润滑油。
维修：如果是制冷剂添加过多，则排出、回收多余的制冷剂；若润滑油加注过多，拭去多余的润滑油到合适的剂量。然后同样要进行抽空、保压、加制冷剂等步骤。
故障六
现象：随着使用时间变长，空调的制冷效果变差，高低压压力都偏低。
成因：使用时各个部件的街头松动。
维修：将松动的接头处重新拧紧。

维修费用
家用空调修理费用要多少？
其实费用的问题，还是要根据维修程度来看，大部分可以分为小修、中修、大修。
1、小程度修理
小城府的修理，原因一般都是小零件故障、家用空调有噪音出现等等，问题不大，修理费用也没有那么多，一般价格在50-100元之间。
2、中程度修理
中修的价格可能在100-300元之间，大多是因为家用空调上的一些零件要更换，比如更换挂机底座、组件、柜机箱体等等。
3、大程度修理
大修的价格则在300-1000元之间，具体什么问题，就需要根据家用空调实际故障而定。

空调保养
1、经常清扫空调器面板和机壳的灰尘
一般使用干布擦拭。先擦拭，然后再用清水湿擦布擦除掉洗涤剂。切勿用40度以上热水、汽油、挥发性油及腐蚀性溶剂擦拭空调器面板和机壳。不应用硬毛刷刷洗空调器，以免损坏外壳，造成脱漆、褪色等。
2、定期清洗空调器的冷凝器和蒸发器盘管
可使用毛刷和吸尘器清洗盘管上的灰尘。注意在清洗时毛刷和吸尘器应沿盘管的垂直方向清扫，切勿沿水平方向清扫，以免碰坏盘管的肋片。
3、定期清洗空调器的空气过滤网
一般2至3周左右清扫一次。清扫时将过滤网抽出，用干的软毛刷刷去过滤网上的灰尘。也可用清水清洗去过滤网上的灰尘。晾干后再装入空调器使用。对灰尘较多的环境，过滤网的清洗应更经常，以免过滤网沾灰尘太多，影响空调器的通风量。

2. vc9801a万用表怎么测电容
胜利万用表是国产三大数字万用表品牌（胜利，优利德，华谊）之一，性价比不错的。
此款表具有的功能：电容，电阻，交、直流电压，交、直流电流，火线判断，方波输出等功能，没有频率，温度，电导等功能，这款表感觉性价比挺高。
3. vc9805a万用表如何测量电容
如果没有电容档。可以利用电阻档来测量电容之间的电阻值，便能得知好坏。
4. vc9806万用表电容档的使用方法
200KHz不能归零，可能是频率挡有滤波电容失效，如果排除这个那么是A/D转换器部分，还有 200KHz挡不能归零，数值在三个字节以内也是属于正常。
5. vc9802a万用表测电容
使用电阻档测，先短接电容的二个脚进行放电，然后红表笔接正极，黑表笔接负极，如果有数据并且这个数据一直在增大，最后显示1，一般就是好的。
1、估测微波法级电容容量的大小：可凭经验或参照相同容量的标准电容，根据指针摆动的最大幅度来判定。
2、估测皮法级电容容量大小：要用R×10kΩ档，但只能测到1000pF以上的电容。对1000pF或稍大一点的电容，只要表针稍有摆动，即可认为容量够了。
3、测电容是否漏电：对一千微法以上的电容，可先用R×10Ω档将其快速充电，并初步估测电容容量，然后改到R×1kΩ档继续测一会儿，这时指针不应回返，而应停在或十分接近∞处，否则就是有漏电现象。
4、把功能开关调到20uF或200uF档，表笔在中间两个孔中，表笔分别去测电容两极，这时就会显示其容量。如果是用过的电容，测量前一定要先放电。
6. vc830l万用表能测电容吗
首先这款表不具有电容容量测量功能； 用此款表如果想简单的判断，先对电容放电，可以用电阻档，红表笔对正，黑表笔对负，测量刚开始时数字乱跳，慢慢变成无穷大，充电过程完成，可以认为基本是好的（对于电容，代换法是不错的选择）。
