5. Once the correct mA value is reached, save the value pressing “Reset”
push-button (one beep will sound and the saved value is shown on the
kVp Display). It is important to write down this data for later reference
during calibration (Refer to Table 3-1).
Once a value for filament current is saved, the value remains in
memory for the next mA station. This feature helps to save time at
entering new data for the next station.
6. Repeat above procedure to calibrate the Filament Current for 80 kVp at
the lowest mA station in Large Focal Spot. The Filament Current value
is few steps below the one calibrated for 40 kVp. (
Refer to Table 3-1) .
The calibration data for Filament Current should not be repeated
at any station.
Table 3-1
Calibration Data for Reference
kVp mA Value Example
40 Minimum Station 707
80 Minimum Station 702
Values above 999 are shown on kVp display as “= XX”, a.e. “=23“
means 1023.
7. To exit Calibration Mode, press and hold “Collimator Light” push-button
and then press and release “mAs Increase” push-button (two beeps
sound). Then release “Collimator Light” push-button.
