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.

Packaged with this unit, you will nd:

A SOR series dosimeter.•

The SOR Quick User’s Guide.•

A battery tool for easily removing the clip and battery cover.•

A reset tool for quickly resetting a powered down SOR.•

Please not that there are no serviceable parts inside the SOR , and that tampering

with the case or removing the warranty seal will compromise the waterproof and

EMI resistant characteristics, and void the warranty.

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

and will cause short circuits and/or potential damage to the device.

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

turn with the battery tool.

5. Replace the clip, sliding it in the rails on the back of the dosimeter until it

clicks and locks into place.

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

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

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

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.
