Features
Various display modes
The results of parameter measurement are displayed in numerical as well as graphical formats. Numerical format offers general and simple mode to display various parameters. The general mode can display 10 measurement parameters (Two main measurements + 8 monitoring measurements), and the simple mode can display four measurement parameters. These displayed parameters can be arbitrarily selected from 25 power parameters according to user requirements. The graphical format can display waveforms of voltage, current and power. The horizontal scale can be adjusted from 25 μs/div to 1 s/div (depends on data update rate). Three magnification levels for waveform are also provided for users to select.
In the harmonic measurement, the measurement result of each order of harmonics can be displayed by bar graphs, and a specific order can be specified for observation. The relevant values of each order of harmonics such as voltage, current, power, voltage distortion ratio, current distortion ratio, power distortion ratio, voltage phase angle, current phase angle can be recorded and displayed.
Rich measurement parameters
This digital power meter provides various measurement functions such as voltage, current, frequency, effective power, apparent power, reactive power, power factor, crest factor, total harmonic distortion, and maximum current ratio. This powere meter is also equipped to measure time integral of power or current for the DUT. Users can set a time window to perform instantaneous power integration at specified intervals and then divide value by total time period to obtain the average power of the DUT.
During integration measurement, this power meter supports automatic level changing function according to DUT power level in order to obtain accurate results.
Auxiliary measurement functions
This digital power meter has rich set of auxiliary measurement functions. High voltage measurements can be done using VT rate setting along with an external voltage potential transformer. To measure currents above 20 A a current transformer can be used and the type of CT determines the instrument settings. When a voltage output type CT is used, measurement can be conducted through the external current sensor input terminals EXT1/EXT2.
In addition, this power meter provides four sets of panel settings for storage/recall and memory for storing 10,000 sets of measurement values. The measurement storage can log the measurement results based upon the update rate or a self-defined time interval to facilitate the subsequent analysis. The USB host on the front panel supports screen capture, measurement value storage, and digital power meter firmware update.
When a current output type CT is used, the CT can be directly connected to current input terminal on the rear panel and setting the appropriate CT ratio state in the Ratio configuration menu.
