5 - 10 Adjustments / Programs
Measurement 5
• Switch on fluoroscopy.
• Read and record the value displayed on the dose rate meter.
• If the value measured exceeds 9 R/min, the maximum tube current must be reduced.
If the value measured is less than 9 R/min, the tube current does not need to be reduced.
• Switch fluoroscopy off.
• Calculate the maximum tube current.
• Multiply the tube current to be programmed by 10 , since entry on the service PC must be
made in 1/10mA. Round off the value to the nearest whole number.
Programming 5
• Connect the service PC to the serial interface of board D1.
• Select the "Adjustment, Parameters" menu.
• In the Combo box "Parameter Groups" select "Limitation of skin dose rate (FL)" .
• Click on "Get from unit" .
• Enter the value to be programmed in "Value" .
• Click on "Set Value".
• Select "Put to unit" . Read the menu guide on the service PC.
• Select "Save to file".
• The value to be programmed has been transferred to the SIREMOBIL Compact and
temporarily stored to the disk.
Checking 5
• After programming, check the maximum skin dose rate again.
tube current displayed at 110kV in mA * 9 R/min
= tube current to be programmed in mA
measured dose rate value in R/min
Example: Tube current displayed at 110kV: 5mA
Maximum skin dose rate: 9R/min
Measured dose rate value : 10.2 R/min.
5 (mA) * 9 (R/min)
10.2 (R/min)
= 4.41 (mA) Rounded to the nearest whole number: 44
The value to be programmed is 44
You must exit the service program with "Logoff" and "Quit".
Only then will the modified parameters be stored on the floppy
disk as a new file.
