Set the meter to display mV.2Soak the measuring tip in pH 4.00 and pH 10.01 calibration solutions. When the readings become stable, record mV val-ues respectively.3When the electrode is used with a R8111 reference elec-trode, the absolute value of the difference between thesetwo mV values should be 326–370 mV in total. This indi-cates that the electrode has a good performance. If not, per-form maintenance on the electrode.Accuracy1Choose any two calibration solutions to calibrate a elec-trode. Use effective calibration solution. Make sure the dis-tilled or deionized water used to prepare the solutionsmeets requirements, and the solution is not contaminatedor beyond its shelf life.2Use this electrode to measure the pH value in anothercalibration solution.3Compare the theoretical value of that calibration solution with the measured value.4Ensure the measuring accuracy of the electrode is sufficient for the application.SamplesThe electrode is only suitable for measuring the pH value ofconventional solutions. Nonaqueous reagents or solutionswith low conductivity or high viscosity may have long mea-surement times, which can affect measurement accuracy.For any other problems during electrode use, contact yourAgilent Technologies customer service representative.

然而，还有多种可以选择的电流探头类型，且每种探头都有最佳应用领域。
当正确用于设计的应用情况时，可以获得最佳的结果。
本应用指南介绍常见的电流探头解决方案类型、基本原理、每种电流探头类型的优势和局限性，以及将电流探头用于示波器应用时的实际考虑因素，从而充分利用这些探头。
电流探头类型电流探头广泛用于功率设备或电源电流测量，它们已经成为使用示波器进行精确的电流测量不可或缺的工具。
为了满足电流测量需求，有很多不同的技术可用来测量电流，但最常见的配合示波器使用的方法有：1. 检测电阻或分流器：基于欧姆定律2. 夹合式电流探头 - 交流电流互感器或混合霍尔效应传感器/交流电流互感器3. 罗氏线圈：用于大交流电流测量的便捷探头检测电阻或分流器测量 DUT 电流的一种直接方式是在电流中使用分流电阻，测量电阻两端的压降，并使用欧姆定律方程式（即，I = V/R）将电压转换为电流。
此方法是有创测定法，其中检测/分流电阻和电压测量电路或探头通过电气连接，并且是待测设备的一部分。
因此，有很多因素需要考虑。
选择检测电阻电阻值、精度、温度系数和物理尺寸的选择均取决于待测量的电流量及其特征。
电阻值越大，SNR 越大，测量精度也越高。
但是，较大的电阻值将导致电阻上功耗的增加，从而产生不需要的电压骤降，其也被称为负担电压。
在负担电压损失以外，还存在检测电阻值和测量噪声、灵敏度和带宽之间的权衡。
为了降低负担电压的影响，用户可能需要尽可能使用最小的检测电阻值，但较低的检测电阻会对测量产生不利影响。
较大的检测电阻值意味着检测电阻上压力骤降的增加，以及负载的低电压，从而引起系统性能和效率问题。
这是一项需要平衡的操作。

Do not proceed beyond a CAUTION notice until the indicated conditions are fully understood and met.SymbolsInstructions for UseThe Agilent 34330A Current Shunt is a precision 0.001Ω resistor housed in a plastic case surrounded by epoxy. Output is 1 mV per A of current passing through the shunt. WARN IN Gvoltage input terminals before use. Do not remove the shunt with a current source still connected, as there may be danger of shorting the banana plugs to ground. Observe the current and volt-age limits listed under “Specifications.” The following simplified diagram shows how the shunt is used:Insert the shunt’s banana-plug outputs into the main voltage inputs on the multimeter (not the high ampere inputs). Then connect the current source to be measured to the shunt’s input terminals (binding posts). The multimeter will read the IR drop caused by the input current through the shunt.The precision resistance of the shunt is 0.001Ω, so the voltage measured by the multimeter is equal to the currentmultiplied by 0.001Ω. Thus, the voltage reading sensitivity is 1 mV/A. For a 15 A current, the voltage reading is 15 mV. Select an appropriate voltage range on the multimeter.

Safety
This manual provides information and warnings essential for operating this equipment in a safe manner and for maintaining it in safe operating condition. Before using this equipment, be sure to carefully read the following warnings, cautions, and notes. NOTE This equipment is designed according to IEC 61010-1 Safety Standards, and has been tested for safety prior to shipment. Incorrect measurement procedures could result in injury or death, as well as damage to the equipment. Please read this manual carefully and be sure that you understand its contents before using the equipment. The manufacturer disclaims all responsibility for any accident or injury except that resulting due to defect in its product. Only trained service personnel who are aware of the hazard involved (for example, fire and electric shock) should perform maintenance on the instrument. When maintenance can be performed without power applied, the power cord must be disconnected from the instrument. To avoid short circuits and accidents that could result in injury or death, use the 1147B only with power lines carrying 300V or less. When conductors being measured carry in excess of the safe voltage level (SELV-E) and not more than 300V, to prevent short circuits and electric shock while the core section is open, make sure that conductors to be measured are insulated with material conforming to (1) Overvoltage Category I, (2) Basic Insulation Requirements for Working Voltages of 300 V, and (3) Pollution Degree 2. Never use this sensor on bare conductors, the core and shield case are not insulated. If a bare conductor is inevitable to be measured, make sure that the power to the wire must be turned off, when opening the jaws of the probe to insert or remove the bare wire so that 300V CAT I is always satisfied. Avoid damaging the cable insulation surfaces while taking measurements. This instrument is only made for use with the Infiniium. Do not plug the probe into any interface other than the AutoProbe interface, of which Infiniium has a protective earthing with double-insulation construction.

Introduction
Introபைடு நூலகம்uction
The 1147B is a wide-band, DC to 50 MHz, active current probe. The probe features low noise and low circuit insertion loss. The intelligent interface makes the probe ideal for use with the InfiniiVision and Infiniium products using the AutoProbe interface. This unique probe interface makes current measurements as simple as those made with the active voltage probes. The 1147B has two operating regions that provide a wide, flat frequency response. In the DC to low frequency AC region, the probe operation is based on the negative feedback of the amplifier system that includes the thin film Hall element as a detector. In the high frequency region, the probe operates as a current transformer. The 1147B is ideal for acquiring high transient time signals such as those found in motor controllers, in switching power supplies, and in current amplifiers driving inductive loads. In order to use this product effectively and to ensure a long operational life, read this user’s guide carefully and retain it for future reference.
