1.Features
1.1 The bench accords with the standard of "IEC 60736:1982 testing
equipment for electrical energy meters", "IEC 62053"
1.2 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).
1.3 The bench can test the converted quantity which is caused by negative
phase, voltage unbalance, harmonic wave and so on.
1.4 The bench can auto-calibrate starting, no load, basic error and
calibration tolerance and 24h deflection.
1.5 Close-link calibration is using insulate current transformer and
suitable for close-link energy meter.
1.6 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.
1.7 The same specification but different constant energy meter can be
tested at one time.
1.8 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.
1.9 The bench can choose to operate by keyboard or PC which is
convenient. The working status of bench can be seen very clear and easy
operation.
1.10 The bench is using the testing software complied with
WINDOWS98/2000/XP which can auto-testing different energy meters.
1.11 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.
1.12 The energy meter hanging rack is made by Aluminum compound.
The whole device configuration is a reasonable design and nice outfit.
