技术问答

U1253B是KEYSIGHT公司新推出的一款具有4.5位分辨率OLED显示器，2000:1对比度的手持式数字万用表，仪器可以采用双屏显示，分辨率高达50000计数，高达0.025%的基本DCV精度使得仪器有着超预期的强大功能特性和性能指标，满足用户最苛刻的测量要求和应用需要。U1253B便携式数字万用表添加了数据记录特性，同时新增了20MHz频率计数器和可编程方波发生器，可让用户更方便地执行更多的数据测量，该款型号随机配备了全套附件无需另外付费，以提供更完善的测量服务。

U1253B数字万用表下提供160°的宽视角范围，使得用户在正常的观察角度下均可看到正确的读数，无论是在外场还是在工作台前，甚至是在室内光线暗淡、角度偏斜的条件下，用户都能看到非常清晰的显示屏画面，具有非常好的数值可视性。该款万用表还可对非常隐蔽的问题进行故障排查，用户可利用仪器的数据记录功能，手动记录每一个读数或以指定间隔来记录。更方便的是通过可选的IR-USB电缆将数字万用表与PC连接，能够保存几乎无限的数据记录以用于进一步分析。万用表测量采用的模式为真有效值和交流+直流，SHIFT快捷键和一站式功能键支持快速信号接入，包括温度和电容等丰富的测量功能，同时内置的电池充电功能可提供最佳的电池蓄电量，在手动测量时能够持续长久地提供电量，为用户手持便携测量提供了卓越的可靠性。

U1253B便携式数字万用表的外观形状

U1253B便携式数字万用表外部采用了坚固的注塑机箱，已经达到CAT III 1000V和CAT IV 600V的安全防护等级，并且在–20°C至+55°C的温度范围内能高稳定性工作。同时数字万用表内部还配有高达30 KA的高能保险丝，保险丝即使在高电流测量中也不会发生严重故障，使用专门设计的4毫米尖探头探测近接点时，减少因电弧闪光造成人身伤害的危险，因此可确保用户自信安全地执行日常的测量。U1253B数字万用表造型坚固，通过了严格的工业标准认证，即使无意掉落在地面也能保证正常的工作性能，该款数字万用表可广泛应用在消费类、工业类等通用电子系统开发的电学特性测量领域。

U1253B数字万用表电压的测量精度(读数的%+最低有效位数)可分为±0.05+50(50.0mV量程)、0.025+5(500mV~50V量程)和0.03+5(500V, 1000V量程)三挡。进行电阻、电流和二极管测试时均可达到良好的测量精度，同时值得注意的测量信号前必须使用开路测试引线用过NULL功能消除热效应，否则直流电流测量精度要增加20个字，连续测量高达10A的电流后（最长时间30S）建议使用两倍的测量时间冷却电表以防内部过热，冷却后方可继续执行测量。

U1253B数字万用表采用小尺寸的封装，产品占用的空间小非常便于携带，尺寸规格(H×W×D)为203.5mm×94.4mm×59.0mm，电磁兼容EMC一致性经过了IEC/EN61326：2002，CISPR11认证，相当于第1组A类，主单元保修3年，标配附件保修3个月，让用户没有后顾之忧。

U1253B便携式数字万用表的特点及优势：

· 可以采用双屏显示，分辨率高达50000计数，高达0.025%的基本DCV精度；

· 新增了20MHz频率计数器和可编程方波发生器，可让用户更方便地执行更多的数据测量；

· 通过可选的IR-USB电缆将数字万用表与PC连接，能够保存几乎无限的数据记录以用于进一步分析；

· SHIFT快捷键和一站式功能键支持快速信号接入，包括温度和电容等丰富的测量功能；

· 内部还配有高达30 KA的高能保险丝，保险丝即使在高电流测量中也不会发生严重故障；

· 电压的测量精度(读数的%+最低有效位数)可分为±0.05+50(50.0mV量程)、0.025+5(500mV~50V量程)和

0.03+5(500V, 1000V量程)三挡；

· 使用专门设计的4毫米尖探头探测近接点时，减少因电弧闪光造成人身伤害的危险；

· 真有效值和交流+直流测量模式

U1253B便携式数字万用表的典型应用：

· 开关功率器件的电学特性测量

· 直流-直流(DC-DC)转换器、D类放大器的电学特性测量

· 数字系统设计的电学特性测量

· 其他通用电路系统的电学测量

万用表真有效值是什么意思？数字万用表如何测量有效值电压和有效值电流？

有效值(RMS)是对波形中所包含能量进行测量的结果, 是指交流电在一个周期内所做的功与直流电所做的功等效这一观点来定义的。电流RMS是指电流有效值，比电流值能更准确地放映电流特性。介绍关于万用表的使用方法的37个问题。
