6.3.4 Stop Delay
If a stop delay (delay before the measure-
ment stops) has been set, the NOMEX
multimeter waits for this time to elapse
after the detection of the automatic end
of the measurement. The measurement
is then considered completed and is ter-
minated.
The following settings are available for the stop
delay:
–
Off
,
i.e., the stop delay is automatically set to
100 ms
–
1 s
,
i.e., the stop delay is 1 s
– …
–
5 s
,
i.e., the stop delay is 5 s.
Periods of more than 1 second may be use-
ful if, for example, radiation intervals longer than
1 second are expected. This allows the total dose
of multiple radiation pulses with long intervals to
be measured.
6.3.5 kV Range
The following settings are available for
the kV range (tube voltage range):
– automatic adjustment of the kV range
Auto
– manual adjustment of the kV range
The automatic adjustment of the kV range is the
easiest and most accurate method for the mea-
surement of an unknown signal. The NOMEX
multimeter automatically determines the correct
measuring range. As a general rule, PTW recom-
mends performing measurements with the auto-
matic kV range setting.
The following kV ranges can be set manually:
RAD/FLU/
DENT
[kV]
CT
DENT-PAN
[kV]
MAM
[kV]
40 … 75
60 … 115
90 … 150
60 … 115
90 … 150
23 … 35
NOTE
At power-up or when the application is
changed, the kV range is automatically set to
Auto
.
For MAM applications, it is
not
possible to select
the kV range.
