| MST-8555 Audio Automatic Inspection System |
 |
This automatic inspection system consists of its oscillator unit, measuring unit, and control unit according to its measuring purposes to inspect AF amplifiers, FM/AM radio units, and other digital and audio products.
Its measuring program can easily be prepared by inputting numeric values according to the EXCEL format and selecting each setting, and it can be transferred to the system by RS-232C and USB memory.
This system can also set the inspection items of a measured unit by means of infrared remote control and it can write serial No., lot No., etc. to its measuring program by the bar code reader. (Option)
Each unit can display the setting conditions by means of LED, and it can confirm the meter indications and GO (acceptable) / NO (rejected) decision of measured values at the same time.
Measuring data are stored in the controller and they can be printed out or saved into PC as occasion demands. |

| ■ |
The measuring program can easily be prepared and changed by using the EXCEL format. |
| ■ |
Measurement can be stopped halfway in a rejected (NG) item or rejected items (NG items) can be indicated at the end of measurement. |
| ■ |
Measuring time can be set according to individual measuring contents. |
| ■ |
L, R 16-channel input / output terminals are provided to save the connection time. |
| ■ |
Since each unit indicates setting, measuring contents can easily be confirmed. |
| ■ |
Measurement can easily be done on the right and left sides, so that the measuring time can be shorted. |
| ■ |
A large meter is provided on the right and left sides so that measuring values can easily be seen. |
| ■ |
Since measuring data are stored into memory of the control unit automatically, they can be printed or saved into PC by using USB memory, etc. |
