Welcome
The SOR Series Electronic Dosimeter
The SOR/R and its sister products (DMC 2000 X, XB, GN; SOR/RF, T) have been
the industry standard in personal radiation protection for over a decade. In
keeping with the Mirion Technologies goal of providing systems to protect
people from nuclear risks, it is designed to provide superior measurement and
alarm capabilities in a compact size.
Do not let the SOR battery completely discharge. The SOR will notify you when
the battery needs changing. Letting the battery completely discharge can result in
errors requiring additional hardware to reset.
Important notes before going forward:
Use only approved batteries in the SOR (see page 3). Other batteries may result in
damage to the device.

Changing the battery on the SOR
Note: The battery on the SOR S should be changed when the “BA LO” or “DF BAT”
warnings are displayed. Waiting until the dosimeter is completely dead can result in
errors requiring reader hardware to reset.
1.Removetheclip.Usingasmallatheadscrewdriverorsimilartool,
gently lift up the tab at the top of the clip and slide the clip assembly off
the back of the dosimeter. Only a slight amount of pressure is needed.
2. Remove the battery cover. Using either a provided battery tool or a watch
case wrench or similar tool, unscrew the battery cover.
3. Insert a Renata CR2450N or Toshiba 2450 battery in the battery

gure 1: Note the yellow insulator that should be present. The cutout portion of
it should reveal the positive contact as shown at A.
4. Replace the battery cover, tightening it to hand-tight plus an additional ¼

Display Cause Solution
SOR is in run mode and the battery is
nearly discharged. The BA LOX display
indicates X hours life remaining.
-Change battery before the SOR loses
power completely.
-Verify the protective insulator is
installed under the battery.
SOR is in pause mode and the battery
is near dead. The battery will die
within 72 hours if the SOR remains in
pause mode.
-Change battery before the SOR loses
power completely.
-Allowing the battery to completely
discharge may result in further errors.
Dosimeter is completely
without power.
-Change battery.
-Reset the dosimeter (page 8)
-ContactMGPIforvericationofdevice
parameters.
Missing bit/pointer in the histogram.
Can occur when the battery is allowed
to discharge completely before
being changed.
-ContactMGPIforvericationofdevice
parameters.
-Requires additional hardware (reader)
to clear.
Loss of calibration factor data stored in
the SOR’s memory.
-ContactMGPIforvericationofdevice
parameters.
-Requires additional hardware (reader)
to clear.
Physical, internal problem related to
the SOR’s detection circuit; or miss-
ing/incorrect parameters related to
detection.
-ContactMGPIforvericationofdevice
parameters.
-Requires additional hardware (reader)
to clear.
Problem accessing data saved
in memory.
-ContactMGPIforvericationofdevice
parameters.
-Requires additional hardware (reader)
to clear.
Internal detector calibration data
missing or corrupt, usually due to the
battery being allowed to discharge
completely before being changed.
-ContactMGPIforvericationofdevice
parameters.
-Requires additional hardware (reader)
to clear.
External detector calibration data
missing or corrupted, usually due to
the battery being allowed to discharge
completely before being changed.
-ContactMGPIforvericationofdevice
parameters.
-Requires additional hardware (reader)
to clear.
Fault in the component used for the
pulse counting.
-ContactMGPIforvericationofdevice
parameters.
-May require additional hardware
(reader) to clear.
Microprocessor hung between pause
and run, usually resulting from the
battery being allowed to discharge
before being changed. Also potentially
due to non-authorized battery types
being installed.
-Remove the battery, inspect battery
compartment for damage.
-Reset using the battery reset tool.

Mirion Technologies Health Physics Division Upkeep
Using the SOR Reset Tool
8
If the battery is not changed while in the “Ba LO” mode and a dead battery
remains in the dosimeter for a prolonged period of time, the SOR might retain
a slight charge and be non-responsive to a new battery. If this is the case, you
can use the SOR reset tool provided with your purchase. If you do not have
the reset tool handy, leaving the battery out of the SOR for 3-4 days will also
sufcientlydischargethedosimetertoacceptanewbattery.
Open battery compartment (as indicated on page 3) and remove the battery.
Then, remove the orange insulator. Insert the reset tool with the ‘tongue’ point-
ing into the cavity underneath the top-right quadrant of the threaded battery
ring, between the soldered connection and the threaded ring (gure 1, A).
Lever the reset tool down. This should cause the tool to make contact with the
appropriate part of the internal board, discharging the capacitor and resetting
the dosimeter.
gure 1: Newer models of the SOR series may have a different appearance.
However, the reset tool should still be placed in the same location.
Replace the insulator as outlined on page 3, gure 2. Insert a new battery, and
attempt to power up the device. There may be error messages that require
additional hardware to clear.
Checking the Battery on the SOR
A B
gure 2
Using a voltmeter, you can measure
the battery level on the SOR through
the ISO connector on the front face.
Simply place the leads at Aand B
shown in gure 2.
If the voltage is between 2.8V DC and
3.0V DC, the battery is still good. The
battery should be changed, however, if
the level is below 2.8V DC.

Glossary
Important Terms about the SOR
Autonomous Mode - The SOR is capable of being turned on and off through
the use of a push button, also called “standalone mode.”
Battery Tool - Stainless steel (gure 1) tool available from Mirion Technologies
for removing the battery cover on the SOR . Mirion part
number D20-2005.
gure 1
Chirp Rate - Setting that causes the SOR to occasionally “chirp” every time it
reads a set quantity of radiation. Default turned off, can be adjusted with a
reader and software.
Dose - The total amount of radiation measured by the SOR with in run mode.
Displayed in mrem or mSv.
Dose Alarm Threshold - The dose set point at which the SOR will begin to
alarm. The Dose alarm will continue past this amount until the SOR is reset.
Dose Rate - The intensity of the radiation being measured by the SOR in run
mode.Displayedinmrem/hormSv/h,conguredatpurchaseorwithareader
and software.
Histogram-AhistorylecreatedbytheSORduringeachuse,notinginfor-
mation such as dose received, alarms triggered, and any faults. Saved to the
memory. Accessible with a reader and software.
ISO Connector - The gold panel on the front of the SOR, used as a connector
for peripherals such as a transmitter. Also used for measuring battery voltage.
Pause Mode - Effectively “off,” as the SOR is not measuring or tracking dose.
Unless a custom display is requested, the display will read PAUSE. (gure 2)
:PAUSE
hp
gure 2
Rate Alarm Threshold - The rate set point at which the SOR will begin to
alarm. The rate alarm will continue for as long as the measured rate is above
this amount, and will cease once it falls back below it.
Run Mode - Also “active” mode, the SOR in run is actively measuring and track-
ing dose and rate. (gure 3)
gure 3 d: 0 mrem
hp
Satellite Mode - The SOR requires software and a reader to be turned on and
off, and to access or change parameters.
Reader - Refers to any hardware (LDM 220, LDM 210, LDM ) available from
Mirion Technologies that is used to communicate with the SOR and alter set-
tings and/or retrieve a histogram.
