NOTES: 1) Some of the values with * should be entered manually following the numeric trend, the values with -- are not calibrated.
2) mA and kVp ranges depend on the Portable Unit model.
2.0 kW Units are calibrated at 40, 80 and 100 kVp.
4.0 kW and 8.0 kW Units are calibrated at 40, 80 and 110 kVp.
It is suggested to write down the Autocalibration or Manual
Calibration data in the table below. Keep in mind that pressing
“mA” to check a value, the data will be increased in 1 point.
Example: in order to read the Calibration value for 80 kVp, 25 mA
and Large Focal Spot, press “kVp Increase/Decrease”
push-buttons to select 80 kVp, press” mAs Increase/Decrease” to
select 25 mAs and then press “mA”. The kVp display shows 802,
the correct value is 801. To check the following mA station,
press
twice “mAs Increase” and once “mA”.The display shows 824 while
the correct value is 823.
