*1 : The full scale value : 3Vrms with As-114B, 4Vrms with As-128, 6Vrms with As-130.
The output voltage is calibrated with our High voltage divider.
*2 : CCFL test bench can be manufactured according to customer's request of CCFL's length and shape.
*3 : We can also make a test bench that functions at -30ºC. |
