i) Small focus size: 0.6mm.
Big focus size: 1.8mm
j) Total filtration: 3mmAl (including the collimator), Fixed additional filtration:
1mmAl
k) Collimator: continuously adjustable, with the cross display for confirming the
position of the image receiver.
l) Indicator timing: not less than 30s.
m) Minimum X-ray radiation field: ≤ 5cm × 5cm @ 100cm SID.
n) Maximum X-ray radiation field: ≤ 35cm × 35cm @ 65cm SID.
o) Operating mode: continuous operation. If one exposure is done, the exposure
function will be locked by the device. Now the exposure is not available, while
other functions are still available for normal use. Wait for 60s before the device
unlocks the exposure function and performing the second exposure.
