Scope of Application
 

XL-A825 Supercharging Pile Verification Instrument Calibration Extension Device Based on the existing DC charging pile verification instrument calibration device, it realizes the function expansion for supercharging pile verification instruments. The device integrates ultra-high precision voltage ratio standards (0.005 level/0.01 level optional), ultra-high precision current ratio standards (0.005 level/0.01 level optional), and a wide-range DC standard source into one unit, adopting a modular design. The ultra-high precision voltage ratio standards and ultra-high precision current ratio standards can be detached for inspection. Together with the DC charging pile verification instrument calibration device, according to relevant calibration regulations, it can perform initial calibration, subsequent calibration, and in-use inspection of electric vehicle DC charging machine verification instruments. It is suitable for accuracy testing and calibration of charging equipment testers and expands the detection capabilities of supercharging pile verification instruments for metrology departments, power departments, quality inspection agencies, and testing institutions.
