OPERATOR'S MANUAL FOR THE SYSTEM
MOSFET CF/CR – Each Reader can read up to five (5) dose points. One Standard
Dosimeter = one Dose Point. A Linear Array has five Dose Points and will display
each position on the Flex graphically on the right-hand side of the screen. The
dosimeters numbers are listed next to their corresponding Reader number, e.g. #1-4.
#1 = the Reader Module and –4 = the Dosimeter #4, or Dose Point #4.
Calibration Factor (CFs) units can be mV/cGy/, mV/Gy, or mV/R. The valid range is
0.01 to 9999.99. If you leave any of the CF fields blank, the CF unit will be in "mV
mode" therefore no CF, i.e. the dosimeter mV reading has not been altered. CRs are
optional Correction Factors. When used, CFs and CRs calculate the dose according to
the formula "DOSE = CR (Optional) * [Voltage/CF]". (See Section 7.1 for more
information regarding CFs and CRs.)
The Reader Status section of the screen shows the last time that the Reader status
was verified and is updated each time it is checked. The MOSFET Voltage portion
indicates the total voltage for each dosimeter's position. It will also indicate if a
dosimeter is absent or saturated (exceeded the Reader's dose range) as well as the
Bias setting for each Reader (Standard or High).
The type of MOSFET dosimeter being used as well as the dosimeter position is
displayed graphically. For example, for Standard MOSFETS a picture of a
mobileMOSFET indicating each dosimeter's position will be displayed. If a Linear 5ive
MOSFET Array (which has five positions) is being used, it will show that this is the type
of MOSFET connected to the Reader.
The Battery column provides a graphic indication of the approximate charge state of
each Reader's battery.
4.2 EQUIPMENT SETUP: CONFIGURATION
4.2.1 Connect To Reader Module
mobileMOSFET Software allows you to connect to the Reader Module using either a
cable or wireless transceiver, and automatically determines the type of connection
(wired or wireless) being used. To connect to the Reader, click the Configure button
from the Equipment Setup window (see Figure 4-1: Equipment Set-up Screen).
A separate Reader Configuration window will open where you select the number of
Readers you wish to use (as shown in Figure 4-2: Reader Configuration Window).
