2. Main Features
2.1 Important Functions
32-bit high speed digital signal processor : The calibrator is a powerful calibrator, based on 32-bit high speed 150 MHz DSP and high performance 16-bit AD with 6 channels. The digital multiplier units with multiple functions and wide range of measurement was successfully developed by means of floating point computations. Therefore, a calculating accuracy canbe guaranteed.
To measure active and reactive power, or calculate errors for two energy meters at the same time: Increasing the working efficiency up to two times comparing with the traditional calibrator.
Wiring emulation function: The various wiring methods can be emulated in office by the calibrator without connecting voltage or current signals.This function will be used as a wrong wiring check tool to improve wrong wiring check capability of the field operator.
Error self checking for 5A clamp: The 5A current signal will be generated and output to 5A clamp by calibrator in order to measure errors of the 5A clamp, avoiding the accuracy change problem after long time use, enabling the operator to have a clear picture of the closed status and clear the 5A clamp in time.
Automatic code reading for electronic energy meter (optional): Supporting code scanner and code reading for electronic energy meter automatically.
Wide range scope for current measurement: Up to 500 times scope for current measurement. Up to 10000 times scope for current measurement.The minimum starting current is 1mA. Wiring identification even in No-load condition.
Accumulative function for electronic energy: Capable of calibrating energy meter without electronic energy impulse output.
