You can either select the tube voltage as single parameter or together with dose, dose
rate, and exposure time. As complementary information an estimation of the total
filtration in the beam and type of waveform are made. This features use the kVp filter
R1[4] that also is the default kV range 55 - 105 kV when the instrument is turned on.
The displayed dose value has very little energy dependence since it is automatically
compensated for each exposure since the kV, estimated filtration and the waveform are
measured.

instead of radiography and select
Tube voltage
as parameter. A 200 ms delay is
default.

. Selecting one parameter mode enables you to see the measured
values from a distance of several meters.
If you want to measure the exposure time in
number of pulses you can do so.
