Display Menu
During the test the display briefly shows all possible
characters. The test can be interrupted by activation
of any of the keys. After the test the submenu re-
mains on the display.
The display contrast can be adjusted between 0
and 9. Press
to confirm a selection.
Auto Off [min]
Set the time for DIADOS E to switch off automati-
cally when no controls are activated. The tens and
ones must be set individually and confirmed with
.
Set the tens first. With
ALT
you exit the submenu
without saving changes.
Measuring Delay Time
Set a time between 1 and 5 s. The measuring delay
time is waited after an automatic recognizing of the
signal end. Then the measurement is regarded as
completed and will be finished. Times longer than
1 s are meaningful if radiation distances are bigger
than 1 s to expect. The total dose can be measured
for several radiation pulses with big distances by it.
2.6 Modes of Operation
DIADOS E offers two modes of operation, the
nor-
mal mode
and the
pulsed mode
, which are select-
ed via the MODE key. In the normal mode, the de-
vice measures dose, dose rate and time and a
timed measurement can be performed. In the
pulsed mode, the device measures dose, dose per
pulse and number of pulses.
2.7 Measuring Quantities
DIADOS E measures air kerma
K
a
(unit: Gy), air
kerma rate
a
K
(unit: Gy/s), air kerma length prod-
uct (unit: [Gy*cm] or [R*cm]), air kerma length prod-
uct rate (unit: [Gy*cm/s] or [R*cm/s]). The selection
has to be done in the
Unit
setup menu. The electri-
cal unit C for measurement of the current (unit: A)
or of the charge (unit: C) is also selected in the
setup menu.
NOTE
For measurements where an official calibration is
required, only the following measured quantities
are allowed:
K
