Appendix A. Technical Information 

GXDP-300

Leakage technique factors

PANORAMIC
 

4800 mAs/h, exposure with maximum values

 

(73 kV, 8 mA, 12 s) according to the 1:5 duty cycle 

Measurement bases

The kV is measured by monitoring differentially the current fl owing through 450 
Mohm, 1% feedback resistor connected between the tube anode and ground.
The mA is measured by monitoring current in the HT return line, which equals the 
tube current.

Collimator

TYPE
 BLD-M-1
PRIMARY SLIT
 

Adult panoramic slit only. For child panoramic the exposure time is reduced  

 

to give a reduced length image. 

PRIMARY SLIT SIZE 
 

0.7 - 0.75 x 38 mm

Z-motor 

DUTY-CYCLE
 

-Intermediate use: 6.25%, 25s ON, 400s OFF

Environmental data

OPERATING
 

- Ambient temperature from +10ºC to +40ºC

 

- Relative humidity 10 - 90%, no condensation

STORAGE/TRANSPORTATION
 

- Ambient temperature from -20ºC to +50ºC

 

- Relative humidity 5 - 85% no condensation 

 

- Atmospheric pressure 500 - 1080 mbar
