12 Meter Positions Single Phase Energy Meter Test Bench

Specifications

Features:

1) New-type aluminum material rack; the structure is beautiful and elegant

2) 12 single phase energy meters can be tested simultaneously

3) The tested meters can be same specification but different constant.

The multi-type meters such as single-phase mechanical,

electromechanical and electronic meters can be tested simultaneously

4) Outputting voltage, current, power, phase angle and frequency is

displayed digitally at the PC interface software. Fully automatic meter

testing controlled by computer with friendly-user software

5) Meter Errors can be displayed on each position for mounting meters. When error

exceeds set value, the system will indicate

6) Automatically capture black spots of mechanical and electromechanical

meter, or the LED signal of electronic meter, automatically carry out

start test and no-load test

7) The tested meters can be sampled with scanning head

8) Automatic short current circuit of the idle meter position, self-lock

meter-hanging seat

9) (opitonal)Equipped with time testing apparatus and GPS clock time as the

standard to do broadcasting test of multifunction meters, such as the

daily error, basic frequency error, time error, time interval error and

maximum demand will be tested. All functions can be achieved by

special function keyboard and the computer. The seller shall supply the

buyer with the communication protocol of the RS485 port for GPS clock

10) Automatic warning when the voltage output is short circuit (overload)

and the current output is open circuit (overload)

11) Fully automatic meter testing controlled by computer, intelligent data

processing and network data sharing

12) programmable of reporting table and certificate formats

13) Supports bar code reading to record meter information
