2.1 Configure three-phase standard meter, which can be used for error test and running test; Or

The leader table is used as the benchmark to conduct the word walking test.

2.2. Multiple structural forms, including integrated and separated forms.

2.3 Aluminum alloy watch rack; The meter is hung on both sides, and 24 single-phase electric energy are hung on one side

The other side is hung with 12 three-phase electric energy meters.

2.4 The wiring for word running and withstand voltage test is separated, which is safe and reliable

Point.

2.5. The zigzag and withstand voltage function switches have interlocking functions, and only one can be used

The test is safe and reliable.

2.6. Characters:

♦ Each meter position is equipped with multi-function signal input interface and one-time wiring,

The verification shall be completed at one time according to the regulations.

♦ Each meter bit is equipped with a 6-bit multi-function display box, which can display the number of running pulses

（ 0~ 999999 ）。

♦ Word type power source, PWM power amplifier, with high output power and heating

Small, low failure rate, etc.

♦ Each meter position is equipped with 485 communication interface, which is convenient for multi-function word running test.

♦ Single phase and three-phase running test shall be switched through interlocking switch.

♦ The running results can be uploaded and printed through the management software for data management.

(Optional function)

2.7 Features of withstand voltage part:

♦ Safety protection equipment shall be installed on both sides of the meter rack. When conducting the withstand voltage test

The protective light curtain is safe and convenient.

♦ During the withstand voltage test, each meter position has an audible and visual alarm

When threading, a status indicator light next to the meter bit lights up, indicating the fault meter bit, and

The alarm sounds. The fault meter automatically disconnects the high voltage, which will not affect other meter tests.

♦ Withstand voltage test results can be saved and uploaded via PC

Function. (Optional)

♦ A warning light is set above the device. When the voltage withstand test is conducted, the three color warning light will be turned on

Light O

♦ The withstand voltage tester adopts PWM power amplifier technology, with automatic and manual functions
