AMPLIMAT

Sensitivity:

            high          Sensitivity of basic interface chamber signal amplifier is 4 times higher.
Only possible with PCB EZ150 version 4512 108 05964 and higher, jumper W4 must be in position 1 (factor x4 even if some PCB layouts have a x10 printed)

                             - 'high' should be set in case of TDC (Tomo Density Control) option (only with PCB EZ150 >= 4512 108 05964 with jumper W4 in position 1 = x4).
Exception: If at least one of the Film Screen Combinations of the system has a speed of <200, ‘low’ must be selected.

                             - 'high' should be the recommended range if all film screen combinations of the system are >= 200 (only >= 4512 108 05964 with jumper W4 in position 1 = x4).

                             - Must be high for Digital Diagnost, jumper EZ150 W4 must be in position 1 = x4.

 

            low           (default)

                               !! Must be low in case of PCB EZ150 versions up to and including 4512 108 05963 and versions >= 4512 108 05964 if jumper W4 is in position 3 = x1
'low' must be the recommended range if at least one film screen combination of the system is < 200 (only  >= 4512 108 05964 with jumper W4 in position 3 = x1).
The chamber signal = density voltage "U off"  to the dose rate control input of CU (see 'DRC Logging' - 'AEC' - 'AEC Calculation') should not increase 10VDC.

 

Note

For ‘Photo sensor/ampl. inp.’ at ‘RGDV Data Set A’  high or low settings must also match with the EZ150 W4 jumper setting. The density voltage 'U_off' will al-ways be 1V, but at high settings and W4 = x4 DRC terminates the exposure at 4V.
