The energy meter field-testing instrument is made by using the newest international digital electron technical skill. To use DSP processor, as the axis to install this intelligent comprehensive automation fieldtesting instrument, which comes with a portable computer, the 11.3 colorful display screen, and Chinese characters operation menu suggestion. This instrument is simultaneously able to measure the value of 3 phase parameters as voltage, current, frequency, energy, power factor and etc. In the field, it can test the various types of simulation output transducer and microcomputer transducer, and power meter. The results can be saved for a long term. The user can print out the testing report, and manage the data on the computer. This instruments can communicate with computer by RS-232 port, and save the measuring results into another computer disk. This instrument is having the features of high accuracy, good stability, small volume, easy to carry on energy measuring department and comprehensive automation test.
