Energy Meter Calibration(Optional)

Interface Introduction

Energy meter calibration is specialized in testing module of energy meter for electronics and electromechanics, once the parameters of specified energy meter has been injected to this module, these data can be saved for further usage, User can use the basic parameter interface of energy meter module to default import all the saved energy meter settings in the box of the module, and user could check, edit, delete and add the objectives of energy meter. On the part of viewing, editing, deleting and adding, click to next, new adding and editing will process automatically.

Testing Procedure

1)Testing connection

Fig Testing connection

Energy pulsing input testing line use and supply by manufacturer standard testing line

2) Testing procedure

To set each parameter of energy meter in the software according to chapter 6.5.2 instruction, add test point, start to test, test device will calculate the outputted energy value to energy meter through real output voltage, current, phase and output time. After energy meter receive test device output energy simultaneously, it will output corresponding energy pulsing signal to test device, test device will output energy value and receive energy pulsing signal to prepare, then calculate present testing point error in order to determine the test result.
