GPM-8310, single-phase (1P\/2W) AC power measurement digital power meter, the product test bandwidth up to DC, 0.1Hz ~ 100kHz, using 16bits A\/D, sampling rate of 300kHz, the use of 5\" TFT LCD display, 5-digit digital display It provides 25 kinds of power measurement parameters and high accuracy measurement capability; and also has waveform display (voltage\/current\/power) capability, integral measurement function, harmonic measurement and analysis, external sensor input terminal, various communication interfaces...etc., to assist users to achieve clear, convenient and accurate power measurement.<\/p>\n
GPM-8310 rated direct input voltage 600V, input current 20A, can support small current gear to 5mA (resolution up to 0.1uA), power measurement resolution of 0.1uW, crest factor of up to 3 (half-range up to 6 or 6A), and voltage\/current\/power measurement capability of up to (\u00b1 0.05% readings \u00b1 0.1% gears), and can be According to the selection of different measurement modes, it can provide up to 25 kinds of power measurement parameters, including voltage, current, frequency, power, crest factor, apparent power, invalid power, power factor, phase angle, total harmonic distortion rate, maximum current ratio, and also includes the MATH calculation function. Therefore, it supports the range and accuracy of low current\/low power measurements such as standby power consumption and general power consumption measurements.<\/p>\n
The GPM-8310 also utilizes the advantages of the TFT LCD display to present parameter measurement results both numerically and graphically. In terms of numerical display, the GPM-8310 provides general mode and simple mode, general mode: 10 measurement parameters (2 main measurements + 8 monitoring measurements) can be displayed, and simple mode: 4 measurement parameters, and these parameters can be selected from 25 types of power parameters according to the user's needs. In terms of graphic display, it provides a simple oscilloscope mode to present the three parameters of voltage\/current\/power as waveforms; in addition, the measurement and analysis of the harmonics of the measured signals can be presented as numerical values or bar graphs, which not only meets the need for accuracy and easy readability for process testing, but also meets the diverse measurement needs for R&D, design, and quality verification applications.<\/p>\n
In addition, the GPM-8310 offers a full range of auxiliary measurement mechanisms\/functions. For large voltage measurement, the GPM-8310 provides VT rate setting for use with an external voltage comparator, while for large current measurement, depending on the type of comparator - voltage output type or current output type - the current output type can be directly locked to the rear panel of the machine and measured with CT rate setting, while the voltage output type can be measured through the external current sensor input terminals provided by the GPM-8310 (EXT1\/EXT2). For voltage output type, the measurement can be done through the external current sensor input terminals (EXT1\/EXT2) provided by GPM-8310. Auto shift can be customized to save unnecessary shift time. 10,000 pens of internal memory can be used to store measurement data according to the update rate set by the GPM-8310 or user-defined time intervals for subsequent analysis.<\/p>\n
In terms of data selection and storage, the GPM-8310 provides a variety of communication interfaces RS-232C\/USB device (virtual COM)\/ LAN\/ GPIB, which allows users to write programs to read the measurement results according to their usage habits or with the existing system interface, without the need to increase the cost of purchasing the interface; USB host, which supports the GPM-8310's screen capture, USB host can support GPM-8310's screen capture, access to internal records, and version updates. For external signal control or data loggers, the GPM-8310 also offers an optional Digital I\/O (DA4) interface (factory-installed) that can be connected to external controllers, such as PLCs or data loggers, for automated measurement or long-time logging applications.<\/p>\n
