Can accurately measure voltage current active power reactive power frequency phase Angle power factor and other electrical parameters
It can display the measured voltage and current phasor diagram the users can know the device wiring correctly or not through the analysis of vector diagram .
The current is measured by using the clamp transformer.Because using clamp current transformer measurementthe operators do not need to disconnect current loop can be measured convenient and safety. It can be equipped with different range of clamps according to the user's measurement range.
It can measure and analysis the power quality from the utility grid to the client's use its measure and analysis frequency deviation voltage deviation voltage fluctuation and flicker unbalanced three-phase voltage allowed degrees and power grid harmonic.
Can display the single phase voltage and current waveform and can also show three phase voltage and current waveform. All tests have screen lock function interface to facilitate users to reading and analyze the data.
The load fluctuation monitoring measurement analysis of all kinds of electric equipment under different running condition cause fluctuations to the utility grid power quality. Timing record and store the the change trend of voltage current active power reactive power apparent power frequency phase and other electric power parameters.
It can dynamic monitoring of power equipment when adjustment and operation and help users to solve the problems of the electric power equipment in the process of adjustment and operation.
It is able to test and analysis in the power system reactive power compensation and filtering device dynamic parametersand make quantitative evaluation to the function and technical indicators.
It can set the different storage time according to the set time to store the interval data in a row. Built-in large capacity data storage press 1 minute interval can store more than 18 months in a row can meet the needs of the long-term monitoring sites.
This instrument is with USB interface which makes it easy to copy the data directly from the backstage management computer. Cooperate with powerful data management software the real-time sampling data can be directly uploaded to the background management computer it will be a more comprehensive and more rapid processing in the background.
Have calendar clock function real-time display date and time. Can also save the test data and results of when testing and upload to the computer through serial port through the background management software (optional) to realize the data of computerization management it has powerful statements.
3 minutes without operating liquid crystal display will enter power saving mode automatically to maximum extend battery life.
Conductive silicone keys feel is good long service life reasonable design convenient operation.
Built-in large capacity high performance lithium ion rechargeable batteries charged full can work continuously more than 10 hours.
Small volume light weight easy to carry can be used for field measurement is used also can be used as laboratory standard measuring equipment.
