Specification :

Detail: Product DescriptionSame as ZERA and MTE products. Of course our price is very reasonable.Functions and Features
The bench accord with the standard of " IEC 60736: 1982 testing equipment for electrical energy meter" , " IEC 62053" Close-link and ordinary calibration both can be used, ordinary calibration can be used to test single/ three phase active and reactive energy meter ( up to 0.5 class) , close-link calibration can be used to test single/ three phase active and reactive energy meter ( up to 1 class) The bench can test the converted quantity which is caused by negative phase, voltage unbalance, harmonic wave and so on The bench can auto-calibrate starting, no load, basic error and calibration tolerance and 24h deflection. Close-link calibration is using insulate current transformer and suitable for close-link energy meter. The bench is using the standard power meter with comparison technology to offer the test the error of energy meters. 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. The same specification but different constant energy meter can be tested at one time. For the installed pick-up equipment, can offer 3 ranges adjustment. It is also can be accepted the signal for both round-style energy meter and digital LED energy meter. The bench can choose to operate by keyboard or PC which is very convenient. The working status of bench can be seen very clear and easy operation. The bench is using the testing software complied with WINDOWS98/ 2000/ XP which can auto-testing different energy meters. The software can realize the data from energy meter for statistics, search and management. It also can connect with on-line management for up load the data The energy meter hanging rack is made by Aluminum compound. The whole device configuration is a reasonable design and nice outfit.Technical Parameters:
