HF Series Generators -- RAD Console
Operation
OM-0279R1 36
Perform X-ray Tube warm-up as follows:
•
Close the collimator blades fully.
•
Select 70 kV, 100 mAs, 200 mA and 500 ms exposure.
•
Insure that no one will be exposed.
•
Make a total of three exposures, 15 seconds apart.
Excessive filament evaporation shortens X-ray Tube life.
Minimize evaporation by keeping Exposure “Preparation”
time to an absolute minimum.
4.3 RADIOGRAPHIC OPERATION
RAD operation can be performed in the following modes:
•
Three point control by selecting kVp, mA and Exposure Time
independently.
•
Two point control by selecting kVp and mAs independently. mAs
selection sets the maximum mA available for the selected Focal Spot
and the respective Exposure Time. In this control mode, when kVp value
is increased, the Generator will automatically look for the adequate
combination of mA and Exposure Time factors to avoid the “
Tube
Overload ” warning, keeping constant mAs.
•
One point control by selecting kVp with AEC operations.
•
