Introduction: 

This instrument is a developed instrument to apply the polarity check of speaker to the automatic line. This instrument has stronger durability against the external noise than the previous model and is capable of connecting with sequence of external instrument.

 
Special Feature:

1. Capable of rapid automatic repetitive test with a new measurement method (Built-in one-chip micro computer) 
 2. The result of test is indicated on LED and outputs relay contact that is capable of connecting with an external apparatus. 
 3. Capable of counting the data judged as the positive or the negative 
 4. Capable of connecting with automated machinery through its automatic start function 
 5. If it is required, you can calibrate the cycle of measurement, the characteristics of internal noise and its sensitivity.
