Single Phase Multifunction Energy Meter (overall type) Test Bench (PTC-8125M)

1. Functions

1.1The bench accords with the standard of "IEC 60736: 1982 testing equipment for electrical energy meters".

1.2 It is used to test all kinds of single phase multifunction energy meter, single phase anti-theft electrical energy meter, single phase intelligent energy meter.

1.3 For single phase anti-theft electrical energy meter, through the relays switch, it can separately test the line (L) circuit and natural (N) circuit at one time.


1.4 The bench can automatically do starting test, no load test(creep test), error test(accuracy test), deviation test, 24h variation test and so on.

1.5 It can do the influence tests caused by voltage, frequency, harmonic and so on.

1.6 Multifunction test: Test the day error; Collocate RS485(RS232) communication port every meter.

1.7 The energy meter hanging rack is made by Aluminum compound. The test bench can be installed scanning head.

2. Features

2.1 The multifunction reference meter and power source can be used independently, and it is convenient to repair.

2.2 The bench is using the PWM-PulseWidthModulation, technology to amplify voltage/current output, the high efficiency at >85%, and lower the heat. The PWM can check the malfunction checking, preset, alarm, and protection.

2.3 The MTS software platform is very powerful, the main Operations are in one interface, the operation is extremely easy; And with the SQL SERVER large databases, it is security and stability, the amount of 4data is almost unlimited.

2.4 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(RS232).

2.5 With the server, multi-meters can be tested at one time.

2.6 The test bench has the auto-search black marker function Which can precisely locate the black marker.

2.7 Automatic range switching. The bench can choose to operate by keyboard or PC which is very convenient.

2.8 Electronic protection in case of over load, short circuit and output current open status.

2.9 The whole device configuration is a reasonable design and nice outfit.
