below). If the exchange process is broken (for example, when the cable is disconnected from the
detecting unit), information in the first five groups is cleared.
- DETECTOR
.
Since the detecting unit consists of the high sensitivity and low sensitivity
detectors, this group is divided into two subgroups for input and display of calibration factors of
high and low sensitivity detectors.
- Multiplication factor – the factor that takes into account the detector sensitivity.
- Dead time (formula) – the factor that allows linearizing the cut of counting response of
the detectors at the end of measurement rate.
- Dead time (physical) –
physical “dead” time of the detectors in microseconds that is
normalized by hardware.
- Personal background – personal background of the high sensitivity detector. Personal
background value is given in µSv/h, and will be subtracted from the DER measurement result,
received from high sensitivity detector. Selecting/unselecting the
Personal background indicator
makes it possible to enable/disable operation with personal background to be compatible with the
old version of the BDBG-09 detecting units. In the event of operation with the current version of the
BDBG-09 detecting unit, unselecting the checkbox will make it impossible to receive and send the
calibration factors.
After the program is started, the calibration factors are displayed in the DETECTOR group by
default. Factors saved in the nonvolatile memory of the detecting unit are viewed and corrected with
the help of the
Get factors and Send factors buttons (buttons are described below).
-
Addressing. The address of the detecting unit is saved in its nonvolatile memory. It can be
changed, as well as the calibration factors. Set a new required address in the New block address
input field and then click Change .
If the detecting unit is operated using extended protocol (v1.3), the current response delay factor
to the broadcast query is displayed in the Current delay factor field. This factor is also stored in
the nonvolatile memory of the detecting unit and can be changed. To change it set a required value
in the
New delay factor field and click Change .
Caution! After clicking the Change button, values from the input fields New address and New
delay factor are simultaneously sent to the detecting unit. Therefore, before clicking Change make
sure all values of the input fields are correct.
If the detecting unit is operated using the v1.2 protocol, the Current delay factor and the New
delay factor fields are unavailable and data is not forwarded to the detecting unit.
- Exchange
– exchange parameters for COM-port exchange with the detecting unit.
- Sent – byte sent to the detecting unit.
- Received - byte received from the detecting unit
- Errors
– errors during exchange with the detecting unit. A big number of errors can be the
evidence of the cable fault between the detecting unit and the adapter, or the adapter and the PC.
In the bottom of the
Work window the Control group is located that consists of four buttons:
Get factors , Send factors , Measurement , Stop , and the Query address input field.
With the help of the Query address input field the address of the detecting unit, which will be
used for operation, is set.
Buttons have the following functions:
-
Get factors – clicking this button makes it possible to get calibration factors, saved in the
nonvolatile memory of the detecting unit and display them in the DETECTOR group. If the
detecting unit does not respond, the corresponding diagnostics will be shown, and the factors will
be displayed in the
DETECTOR group by default.
- Send factors – clicking this button allows a user to send calibration factors, displayed in the
DETECTOR group, to the nonvolatile memory of the detecting unit. If the detecting unit does not
respond, the corresponding diagnostics will be displayed.
