Technical Manual
The maximum rated peak tube potential is 84 kV and the maximum rated continuous tube
current is 3 mA for the maximum rated peak tube voltage.
The Radiation port contains additional filtration of at least 2 mm aluminium.
Total filtration min. 2.5 mmAl.
When the X-ray beam is attenuated with the 2.5 mmAl the resulting dose is 0.5 - 0.6 times the
original.

1.5 kW, duty cycle approximately 1:10. The wait period is calculated using the following for-
mula:
t = f(HS - HS ) - f(HS
w MAX 1
where HS = maximum tube anode heat storage capacity (28 kJ)
