1.4 It can auto-calibrate for the verification items such as creeping, starting, basic error, standard deviation and checking constant of the electricity meter.
1.5 It can do the influence test caused by voltage, frequency and harmonic and so on.
1.6 It can do the Multi-function testing of the energy meter.
1.7 It can do the test of error consistency, error variation, load current variation test, current overload test and so on.
1.8 Optional function: carrier communication function test; tariff relay control test; Far/near infrared communication function test; automatically operated of the energy meter.
1.9 The bench is using PWM to modulate power amplifier: the larger output capacity, the smaller volume, the higher output efficiency, the lower heat output, the good load characteristic, the higher reliability.
1.10 Electronic protection in case of over load, short circuit and output current open status.
1.11 The bench is using the error processor system, which can simultaneously verify the errors of different constant electricity meters. And the communication is reliable and fast.
1.12 Every meter has pulse input port which can simultaneous access to energy pulse and second pulse signal. And it is no need second wiring in the process.
1.13 Communication technology can achieve one-to-one meter communication.
1.14 Automatic range switching. The bench can choose to operate by keyboard or PC which is very convenient.
1.15 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 data is almost unlimited.

3. Pneumatic operated type
 
3. 1 Pneumatic device has simple structure and easy to installation and maintenance. The medium is air and safe to use.
3.2 The adjustment of output force and working speed is very easy.
3.3 The device has high reliability and long service life. The number of effective actions of electrical components is about one million times, while the average life is more than 30 million times, and the quality of valves is more than 200 million times.
3.4 For some energy meters, the current terminal uses a basket U-shape (see Figure 1).The ordinary terminal block must be screwed in the measurement, and the manual operated method cannot be used, which greatly reduces the production efficiency. For this reason, we recommend that it is better use a special basket-type Pin (Figure. 2).It must be combined with pneumatic operated to perfectly solve the meter pressure problem (Figure 3) and improve production efficiency.
