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.
