Measurement

•
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.
tube current displayed at 110kV in mA * 9 R/min
measured dose rate value in R/min
•
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.
Example: Tube current displayed at 110kV: 5mA
5 (mA) * 9 (R/min)
10.2 (R/min)

Programming

•
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.
NOTE

Checking

•
After programming, check the maximum skin dose rate again.

System Manual
Maximum skin dose rate:
Measured dose rate value :
= 4.41 (mA)
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.
