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.
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.
