Supplement, Measuring the tube current

•

Switch OFF SIREMOBIL.

•

Remove jumper X97 from board D1.

•

Connect the mA measuring device at D1.X39 and D1.X40.

•

Switch ON SIREMOBIL.

•

Release radiation and read the overall current.

•

Read out the kV value produced while the current is being measured.

Calculate the tube current as follows:

e. g:

At 110 kV, an overall current of 5.275 mA is measured. 

When measuring the tube current, the distribution current must 
be derived from the measured value. The distribution current 
depends upon the kV and is calculated according to Ohm's law. 
The distribution resistance is 400 MOhm.

tube current [mA] = overall current [mA]  -

high voltage [kV]

distribution resistance [MOhm]

tube current [mA] = 5.275 [mA] -

110 [kV]

= 5.275 [mA] - 0.275 [mA] = 5.0 [mA]

400 [MOhm]
