5. Working principle and frame
Introduction: 
1)Signal generator
The   marked parts is included in signal generator board. Signal generator is equipped with DDS waveform technology (digital frequency modulation, amplitude modulation and phase modulation). Embedded MCU is the brain of signal generator, also it is the brain of the instrument, signal generator generate high stability sine waveform which is send to voltage amplifier and current amplifier.
2) Power amplifier
Because the instrument uses integrated PWM amplifier technology, the power amplifier features high stability / high reliability and high efficiency. The amplifier has well-designed protection, when output voltage shortcut or output current circuit open, the alarm system will auto shut down the amplifier, the same time LCD will display which part is out of order. 
3) Measurement
Error of tested meter is achieved by comparison with the reference meter.

8.  Support & FAQs
1) When the voltage circuit is shortcut or voltage amplifier is overloaded , or the current circuit is open, or current amplifier is overloaded, testbench will automatically lower down the output until to zero and  display “ERR” ,It is recommended to lower down the output power, check the wire connection, then restart the power source output if everything is normal.
2) error test is abnormal
Please check whether the preset parameter for the tested meter and the system parameters are correct. Check whether the infrared collector works correctly
3) PTC-8000(Error calculator) doesn’t work correctly
If  PTC-8000(Error calculator) doesn’t work correctly , it can be reset by pushing the button of  “system reset” . In the process of calibrating meter, push the button of “error reset” to re-calculator Error.
4) please contact us if there is any malfunction of the equipment.
If testbench is alarm , please press ‘system reset’ to clear output firstly , after the voice of alarm is stopped, then please check current circuit and check voltage connect wire . the current circuit shouldn’t be open and the output voltage shouldn’t be shortcut.
Warning!!!
There are high voltage at Output and input of the amplifier boxes . It is dangerous to touch by hand. It is forbidden to open amplifier boxes by nonprofessional .
