2.8.3 Lower Range Limit for Dose per Pulse
Measurement
Table 3 shows the lower range limits for dose per
pulse measurements. If the measured value drops
below the lower limit, DIADOS E will display LO
instead of the measured value.
Two asterisks "**" appearing next to a measuring
value indicate an elevated measuring error due to
insufficient resolution.

Table 3: Lower range limit for dose per pulse measurement. Typical values at a minimum resolution of 1% in
dependence of the measurement range. We assume that the pulse duration T
pulse
is shorter than the
interval between two pulses.
