The bench accord with the standard of "IEC 60736:1982 testing equipment for electrical energy meter", "IEC 62053"
Ø Close-link calibration is using insulate current transformer (ICT)and especially suitable for close-link energy meter
Ø The bench can auto-calibrate starting, no load, basic error and voltage influence test ,S value etc.
Ø The bench is using the error processor system to calculate the error of each energy meter by the sub-error system which can be connected by the internal RS485.
Ø The same specification but different constant energy meter can be tested at one time.
Ø The bench can choose to operate by keyboard or PC which is very convenient.
Ø The working status of bench can be seen very clear and easy operation.
Ø The bench is using the testing software complied with WINDOWS98/2000/XP which can auto-testing different energy meters.
Ø The software can realize the data from energy meter for statistics, search and management.
Ø The energy meter hanging rack is made by Aluminum compound. The whole device configuration is a reasonable design and nice outfit.
Accracy class:0.1 and 6 , 12 , 1 6 meter positions are optional
