The Voltech PM6000 combines years of power measurement know-how with the latest digital signal processing technology to provide a unique combination of measurement and reporting features that will solve power measurement problems.Why the PM6000? There is a constant consumer and legislative pressure to design electrical products that are more efficient, power electronics designers use more and more sophisticated control methods and increases in switching frequency to achieve this. Therefore more sophisticated, more accurate and higher bandwidth power measurements are required to validate and test power electronic designs.The PM6000 has been designed especially to meet the needs of today’s design and test engineers by providing greater flexibility and bandwidth at high accuracy.The PM6000 is an advanced digital sampling power analyzer. From 1 to 6 measurement channels may be fitted to a PM6000. Each measuring channel is a separate wattmeter with fully floating inputs for connection to the voltage and current of the power circuit to be measured.Voltages up to 2000 Vpk may be connected directly to the measurements channels and a wide variety of current transducers may be used, including wide-bandwidth resistive current shunts from Voltech. The Voltech shunts plug directly into the measurement channel for convenience, and have the advantage that the shunt’s calibration data is automatically transferred to the PM6000, providing optimum accuracy for the complete measurement path. For other external current transducers, each channel can supply ±12V DC power. Unique and proprietary algorithms are then used to process the samples and provide stable and accurate measurements in all applications.MeasurementsFront PanelThe intuitive menu system will guide you through the set-up and control of the analyzer. Working through the options step-by-step allows you to configure channels into groups for a variety of multi-phase connections, to set scaling for external voltage and current transducers, and to choose the required measurements.Rear PanelAt the rear, comprehensive control is provided via RS232. Standard printers may be connected directly for local print-out of numeric results.The ethernet port allows for powerful control and datalogging to a network drive.Set-Up and Controlcontrolfunction keysAdvantages• U p to six channels configurable as required, for example AC input plus 5 DC outputs or three-phase input and output.• Excellent 0.02% basic accuracy - useful for high efficiency measurements.• Accurate on all waveforms.• Samples continuously, without gaps at 5 MSPS so there is no missing dataduring integration or low-power standby measurements.Power transformers are characterized under open-circuit and short-circuit conditions. Open-circuit, the power factor of the transformer is closeto zero (<0.01), which demands very low phase error, from the power analyzer.The analog design of the PM6000 ensures that its voltage and current channels are carefully matched, providing optimum performance at low power factors.Applications - Power TransformersAdvantages• Up to six channels for simultaneous three-phase input and output – Star (Wye) or Delta connection.• Accurate at low power factors.

NI 9755 SystemHardwareThe NI 9755 includes the following hardware:•Continental UniNOx Smart NOx Sensor with integrated sensor controller module •Sensor bung •Wiring harness •NI-9853 CompactRIO High-Speed CAN moduleThe wiring harness in the NI 9755 connects to the NOx Sensor Control Module and splits into two cables for the NI-9853 module and an external power supply. The first cable connects to the NI-9853 with a female DB-9 connector. A terminating resistor of approximately 120 Ω is located inside this cable near the NOx Sensor Control Module and between the CAN High and CAN Low wires. The second cable provides three non-terminated leads for connecting to a power supply, which requires two leads, and for address selection of the NOx Sensor Module, which requires one lead. If the cable is to be extended, follow CAN network wiring guidelines.Refer to the NI 9853 CAN Module Operating Instructions and Specifications for more information on cabling requirements.NoteYou must use the sensor included in the NI 9755 kit. NI does not support other sensors.Powering the HardwareThe NI 9755 requires power from a range of 12 V to 16 V with a continuous current of 1.5 A and a peak current of 16 A. The maximum power requirement is20W, which typically occurs when the heating element is being turned on from a cold state. If you are using two sensors, double the capacity of the power supply.Refer to the NI 9853 Operating Instructions and Specifications for more information on power requirements.Contact National Instruments for more information about sensor specifications.NOx Sensor Light-Off TimesConditionsAir T.........................................................25 ±5 °CBatt V........................................................14 VHeater........................................................ONNO x...................................................................< 100 sO2......................................................................< 80 sNOx Sensor Preheating FunctionWhen power is supplied to the sensor, the sensor enters preheating mode automatically until the Sensor Enable Boolean is set to TRUE within the supporting software.

为了进一步验证Egteks mPower1203的测试精度,我们使用100kΩ、10kΩ以及1kΩ的电阻负载来验证其真实的电流精度。
将mPower1203设置成电源功能,分别输出0.6V/1V的电压,加载在三种不同的电阻负载上,测试流过的电流,该为下表中的实测电流。
由于电阻和输出电压都有误差存在,所以我们使用福禄克万用表(Fluke 18B+)串入测量出实际电流,对比实测电流和实际电流就可以得出相对的精度。
对于uA级别的电流,mPower1203规格书中提到的是±0.5%±2uA,可以得出表中的数据是和规格书描述一致的。
