但是，⼤多数多⽤表可以测量超量程的量值，即可再加上部分或“1/2”个位数。
例如，HP 34401A 设置在10V量程范围时，测量到 9.99999 VDC，这表⽰分辨率为6个完整的数位。
但是，该表也可以测量超过10V量程的范围，最⼤可以测量到12.00000 VDC. 这就是所谓超过20%的测量范围能⼒和6 1/2 位数的测量。

6. 1 S1240系统结构S1240程控数字电话交换设备具有以下特点：①全数字化②全分布控制S1240系统的控制功能由分布在各个终端和辅助控制单元(ACE)中的微处理机共同完成。
采用全分布控制使得系统的处理能力可以适应不同容量和不同业务的需要。
S1240基础知识第一部分机型简介一、系统结构A1000 S12的功能结构非常简单，它由一个内部交换网络和连接在网络上的不同的模块所构成。
模块的类型和数量取决于交换局的容量和提供的业务. A1000 S12程控交换机的中心是交换网络，所有的模块通过PCM链路连接到网络上。
内部交换网络(又称数字交换网，简称DSN)由一系列按一定拓扑结构连接的交换单元构成，模块数目的增加和话务量的增长，将引起DSN交换级数和平面数的增加。
另一方面，所有模块通过PCM链路连接到DSN。
所有模块都包含一个结构相同的部份－－控制单元(简称CE)，控制单元由一个微处理器及存贮器，和一个连接交换网络的标准接口构成。
控制单元(CE)通常分为两类：终端控制单元(简称TCE)和辅助控制单元(ACE)。
终端控制单元(TCE)含有一个标准接口，这个接口与具有特定模块功能的终端电路相连，比如用户电路，中继电路等。
辅助控制单元(ACE)不含任何终端电路，主要用于完成一些特殊任务，比如：错误处理、字冠分析、本局用户标识。
下面简单介绍一些主要的A1000 S12模块：模拟用户模块(简称ASM)：由一个控制单元和一组用户电路构成，提供到模拟用户的接口。
这些用户电路可以支持不同类型的模拟用户(普通用户、公用投币话机用户、优先级用户等)。
另外，还有综合业务数字网(ISDN)用户模块、移动通信用户模块等。
数字中继模块(简称DTM):由一个控制单元(CE)和数字中继电路构成。
通过标准的PCM链路，数字中继模块作为与外部系统的接口，比如：交换局、小交换机、远端用户单元等。
数字中继模块还可以处理不同的信令类型(多频或数字信令)，当然这是在专门的信令处理模块(服务电路模块和数字信令处理模块)的支持下完成。
外设和负载模块(P&L)：作为与外设(人机通信终端、打印机、磁带、磁盘等)、告警盘和告警灯的接口。
时钟和信号音模块(CTM)：提供系统同步信号和产生必要的电话信号音等。

泰克DMM4020 5.5位台式万用表在一台简便易用的仪器中提供了大量的功能。
它可以以高达0.015%的基本VDC准确度，执行电压、电阻和电流等典型的万用表测量，确保为设计提供所需的仪器性能。
您还可以使用DMM4020测量频率，执行通断测试和二极管测试。
您可以使用一台多功能仪器代替计数器、通断测试仪和传统DMM，节约工作台空间和成本。
测量毫微安培信号测量当前能耗效率高的设计中的待机电流，要求考察非常低的电流，其通常只有几微安或几纳安。
对这种测量，使用传统万用表会导致结果不准确，因为传统万用表一般采用分流电阻技术来测量电流。
DMM4020改进了测量低电流的方法。
通过使用电流到电压功放技术，DMM4020可以以1nA 的分辨率测量电流，给被测电流带来的负荷影响达到最小，其结果反映了设备在实际环境中的工作情况。
第四节微机自动准同期装置的维护Section four Maintenance of microcomputer automatic quasi-synchronization deviceSID-2SL-A型微机多功能同步表技术说明SID-2SL-A type microcomputer multi-functional synchronization meter technical description概述General本装置集同步表和同期闭锁继电器于一体，用于手动同期相位角指示，及手动同期和自动同期同期闭锁功能。
主要功能如下：This device integrates synchronization meter and synchronization blocking relay, used to manual synchronization phase angle indication and manual synchronization and automatic synchronization blocking functions. The major functions are as follows: 1.1 并列点两侧电压相位角指示，用模拟和数字两种方式显示。
1.2 该装置有多达12个同期闭锁继电器，每个同期闭锁继电器可单独整定闭锁角，在外部输入同频或差频并网类别开入量时，被选中的同期闭锁继电器将自动设置与并网性质相对应的同期闭锁角整定值。
1.3 同步表输入的TV二次电压可为相电压、线电压或220V电压。
如果两侧电压存在固有相角差，可通过对每个并列点的系统侧电压单独设置转角进行修正。
1.4 每个并列点可单独设置允许压差、允许频差。
当电压差或频率差超过允许值时，闭锁继电器自动闭锁合闸回路。
1.5 支持单侧无压合闸或双侧无压合闸。
在满足单侧无压合闸或双侧无压合闸条件时，闭锁继电器一直导通，而不需使用其他回路来解除该闭锁继电器。

Agilent U1230 SeriesHandheld Digital Multimeters (DMMs)Data SheetWhether it is dark, noisy or evendangerous, the U1230 Series handheld digital multimeters keep you equipped with features that anticipate worst-case scenarios. The ergonomic shaped handheld allows you to single-handedly illuminate the test area with a built-in flashlight while selecting measurement functions using the rotary dial. Vsense performs non-contact voltage detection while continuity detection is made easy with the audible beeper alert and flashing backlight display. With the U1230 Series, you work better in the conditions you are in.• Built-in LED flashlight to illuminate test area • Flashing backlight as additional visual alert during continuity tests in noisy environments • Vsense to perform non-contact voltage detection • Data logging capability (stores up to 10 readings)• IR-to-USB connectivity to transfer data to PC for recordErgonomically shaped with a built-in flashlightBuilt for handheld users working in a poorly lit environment, the U1230 Series allows you to single-handedly illuminate your test area while making measurements with its easily activated built-in flashlight. Its ergonomicshape fits your hand, while the easily accessible rotary dial allows selection of measurement functions.Flashing backlight and beeping alert for continuity detectionThe U1230 Series is built for con-tinuity detection in dark and noisy environments. Its audible beep and flashing backlight display provides increased visual and audio alert to indicate continuity.Non-contact voltage detection with VsenseThe Vsense, a unique feature found in the U1233A model performs non-contact voltage detection. It delivers more safety while making measurements in dangerous working environments by avoiding any contact with hot or live wires. Upon detection of voltage, it produces a unique combination of beeping alert and blinking LED light to make measure-ments more efficiently – especially in a dark or noisy environment.FeaturesRetool your expectations with the new Agilent U1230 Series Handheld DMMs- the first to combine a built-in LED flashlight, both audible and visual alerts, and non-contact AC voltage detection in one handheld.Take a Closer LookLow input impedance to eliminate ghost voltagemeasurement Anti-slip rotary dial for easy measurementfunction selectionFlashing light and audible beep during presence of voltage 1Bar graph indication and frequency measurement pathVsense performs non-contact voltage detection 1Ease viewing with display backlight or built-in flashlightFigure 1.

The specification above is specified after 60 minutes of warm up time. If the unit is exposed during storage in high humidity (condensing) environ-ment, 120 minutes of operating time is required instead.2. The accuracy does not include the tolerance of the thermocouple probe.3. Do not allow the temperature sensor to contact a surface that is energized above 30 Vrms or 60 V DC. Such voltages poses a shock hazard.4. Ensure that the ambient temperature is stable within ±1 ºC and that the Null function is used to reduce the test lead’s thermal effect and temperature offset. Before using Null function, set the multimeter to measure temperature without ambient compensation (°C) and keep the thermocouple probe as close as possible to the multimeter (avoid contact with any surface that has a different temperature from the ambient temperature).5. When measuring temperature with respect to any temperature calibrator, try to set both the calibrator and multimeter with an external reference (without internal ambient compensation). If both the calibrator and multimeter are set with internal reference (with internal ambient compensation), some deviations may show between the readings of the calibrator and multimeter, This difference is caused from the calibrator and multimeters’s ambient compensation. The deviation can be reduced by keeping the multimeter close to the output terminal of calibrator.6. The temperature calculation is specified according to the safety standards of EN/IEC-60548-1and NIST175.7. The approximate ambient temperature (cold-junction compensation) is shown on the display when you have an open thermocouple. The open thermocouple message may be due to broken (open) probe or because no probe is installed into the input jacks of the multimeter.8. For temperature measurement on U1233A, the type-K thermocouple probe and adapter such as the U1186A (purchase separately) is required.9. For auxillary temperature measurement on U1231A & U1232A, a temperature module such as the U1586B (purchase separately) is required.Frequency specifications99.99 Hz 0.01 Hz 0.1% + 2 5 Hz999.9 Hz 0.1 Hz 0.1% + 29.999 kHz 1 Hz 0.1% + 299.99 kHz10 Hz0.1% + 2Notes:1.
