Introduction
The Model 3005 is an ergonomic, lightweight instrument with an
internal detector used for radiation survey. The instrument features a
large backlit LCD (liquid crystal display), a piercing audio warning, and
easy, intuitive use. The unit body is made of lightweight but durable
plastic. It is intended for outdoor use and can resist splashing water.
Versions: While the standard Model 3005 has an internal EnergyCompensated Geiger-Muller (ECGM) detector, other detectors are
possible:
3005: ECGM with range 0.1-5000 mR/hr or 0.001-50 mSv/h
3005/3: ECGM with range 0.1-25000 mR/hr or 0.001-250 mSv/h
3005/4: ECGM with range 1-50000 mR/hr or 0.001-500 mSv/h
Three modes of operation are available for the Model 3005 – RATE,
MAX, and COUNT. RATE mode operation will display the current
exposure, or dose rate. MAX mode is used to capture the highest
exposure or dose rate detected – useful for finding a peak rate when the
display is not visible. Two sets of units (primary and secondary) for
RATE and MAX modes can be chosen from among cps, cpm, Bq,
dpm, R/h, or Sv/h. The user can switch between these two units by
simply tapping the Units button. If not needed, the 2nd set of units can
be disabled. Also, the additional MAX and COUNT modes may also be
disabled, reducing the possible number of displays the user may
confront.
COUNT mode allows the user to perform a count for a predetermined
time. Depending on the count units chosen, the result can be a scaler
count (in counts or disintegrations), a time-averaged rate (cpm, dpm,
Bq, cps), a time-averaged exposure or dose (R/h, Sv/h), or an
integrated exposure or dose (R or Sv).
The display will be automatically backlit if light levels are low. The
display backlight can also be configured for “Continuous On”

The Model 3005 comes with the ability to log measurements to memory
for later download. The optional Ludlum Lumic Datalog software is
needed to download this memory, however. The unit can log up to
1000 measurements, and it adds a date/time stamp to each
measurement.

Model 3005 Gamma Survey Meter User’s Manual Section 1
Front-panel setup can be disabled via the internal switch on the Model
3005 in order to protect settings from inadvertent changes.
The unit is operated with four alkaline AA batteries for operation from
-20 to 50 °C (-5 to 122 °F). Battery life is approximately 750 hours
under normal usage. A low-battery indicator on the LCD warns when
less than 16 hours of battery life remain.

Getting Started
Unpacking and Repacking
Remove the calibration certificate and place it in a secure location. Remove
the instrument and ensure that all of the items listed on the packing list are
in the carton. Check individual item serial numbers and ensure calibration
certificates match between instruments and detectors (if applicable). The
Model 3005 serial number is located on a label on the front side of the unit.
To return an instrument for repair or calibration, provide sufficient packing
material to prevent damage during shipment.
Every returned instrument must be accompanied by an Instrument
Return Form, which can be downloaded from the Ludlum website at
www.ludlums.com. Find the form by clicking the “Support” tab and
selecting “Repair and Calibration” from the drop-down menu. Then choose
the appropriate Repair and Calibration division where you will find a link to
the form.
Battery Installation
A low-battery indicator appears at the bottom of the LCD when less than
16 hours of battery life remain. When this indicator is present, follow these
steps to replace the four standard AA batteries:
Ludlum Measurements, Inc. Page 2-1 July 2017
Model 3005 Gamma Survey Meter User’s Manual Section 2
Instrument Operational Test
Turn the instrument ON by pressing the ON/ACK button for about a
second, and then releasing.
The instrument should activate all the LCD segments and the audio.
Observe the device during this time. If any LCD segments are missing, or
audio fails to work, the device is in need of repair. Please refer to Figure 1
below.
Figure 1: Startup display for Model 3005, with all LCD segments shown.
The instrument then displays the firmware version. Please refer to Figure 2
below.
Figure 2: Firmware version display.
Note: Firmware Versions with the Bq displayed support auxiliary
communication.
The instrument then displays the battery voltage. Please refer to Figure 3.
Ludlum Measurements, Inc. Page 2-2 July 2017
Model 3005 Gamma Survey Meter User’s Manual Section 2
Figure 3: Battery Voltage display
The instrument then displays the number of stored records if data logging is
enabled. Please refer to Figure 4 below.
Figure 4: Startup display for Optional Data Logging firmware, showing
155 stored records.
The instrument will then move to normal operation, displaying the current
rate for the Primary units (default: µR/hr).
If the Sigma Audio option is selected, the unit will display a countdown
from :08 to :01 (in seconds) as the unit measures background radiation
levels. Note that the Sigma Audio option is intended for scintillation
detectors and will generally not work well for the GM detectors used in the
Model 3005, 3005/3 and 3005/4.
The user may select the Secondary units (default: cpm) by tapping the Units
button.
Ludlum Measurements, Inc. Page 2-3 July 2017
Model 3005 Gamma Survey Meter User’s Manual Section 2
Ensure that the low-battery indicator is not present. If the low-battery
indicator is present, replace the batteries as soon as possible. Should the
instrument detect a battery voltage that is high enough to power on, but too
low to safely operate, the display will blank and the low-battery icon will
flash. Normal operation will not be available until the batteries have been
replaced. Under extreme low-battery conditions, be aware that the unit may
not even turn on or may turn itself off abruptly.
A reference reading with a check source, 1 µCi (37 kBq) of
137
Cs for
example, should be obtained at the time the instrument is received in the
field. Small check sources of radiation are available from Ludlum
Measurements. While exempt from many regulations because of their small
size, these sources are large enough to produce a response on this
instrument. If this procedure is done routinely with the same radiation
source, instrument malfunction may be detected when anomalous readings
are observed. If at any time the instrument fails to read within 20% of the
reference reading when using the same check source, it should be sent to a
calibration facility for recalibration and/or repair.
Example log reading:
Check Source # Rate Units
Once this procedure has been completed, the instrument is ready for use.

Model 3005 Gamma Survey Meter User’s Manual Section 2
Detector Failure Diagnostic
Note that the Model 3005 has its own diagnostic tests to ensure that the
detector is functioning correctly. The Model 3005 can detect when the
radiation detector is malfunctioning and will flash the display to indicate a
fault. If the detector stops detecting radiation for a settable number of
seconds, the Model 3005 will flash a zero reading for the currently selected
units. This indication is common if the unit is powered up without a
detector connected. If this indication is observed with a connected detector,
remove the unit from service and have it evaluated by a qualified repair and
calibration technician.
Figure 5: Detector Failure display (shown for cpm); will also flash.
Detector Over Range
If the detector is exposed to high levels of radiation or has an internal
malfunction that causes it to count high or excessively, the unit flashes the
maximum rate (999) for the currently selected units as a warning. The user
should ensure whether this is being caused by a high radiation field or by
internal malfunction. With some detectors, this display could be an indicator
of a light leak, possibly caused by a puncture or tear in the detector face. If a
Maximum Display parameter is set, then it is possible for the display to flash
the Maximum Display value under this condition.
Figure 6: Detector Over Range (shown for cpm); will also flash.
Ludlum Measurements, Inc. Page 2-5 July 2017
Model 3005 Gamma Survey Meter User’s Manual Section 2
Detector Overload
As another diagnostic test, the Model 3005 monitors the HV supply's
detector current. A current overload threshold can be set via Setup Mode.
(A setting of 0 disables this alarm.) In general, this alarm setting can be used
to detect when there is some detector failure, a cable failure, or a possible
high level of radiation. When this alarm is triggered, the LCD will display
OL and an alarm tone will sound. Once the detector current goes below the
threshold, the Model 3005 will return to normal operation.
Figure 7: Detector Overload Alarm; will also flash.
Instrument Use and Controls
With four front-panel buttons, the Ludlum Model 3005 is simple and easy
to use with minimal training required. Default operation is RATE mode,
and the display shows the current count rate using the Primary units.
Tapping the UNITS button will switch between Primary and Secondary
units. Long-pressing the MODE button will switch the instrument to MAX
mode, which will display the highest count rate detected. Long-pressing the
MODE button again will switch to COUNT mode, which will display the

Ludlum Measurements, Inc. Page 2-9 July 2017
Model 3005 Gamma Survey Meter User’s Manual Section 2
COUNT Mode Operation
When entering COUNT Mode from another operational mode, the
currently selected COUNT Units will be displayed for approximately one
second. The purpose of COUNT mode is to count for a predetermined
amount of time, and to display the results on the display. Note that the
predetermined count time can be from 1 second to 10 minutes, or can be set
to zero to enable continuous counting until stopped by the user.
Count mode operation is very flexible, depending on the units chosen. A
common choice is for the count mode to just perform a scaler count for a
specified time, with a resulting answer in counts (equaling detected radiation
events).
There are two different options for COUNT mode, which can be set
through software.
Go to “Device Count Display Mode” in the Device or Others tab
(depending on Software version). Enter/Select the desired option into the
“Value” field.
0 - will only show the count-down timer while timer is active
(default selection).
1 - will cycle between showing the count-down timer and the
current reading.
2 - will only show the current gathered reading.
Note:
If the Data Logging Option is installed, tapping the LOG
button will start a count and automatically log the result. A
long press of the LOG button during the count will toggle the
display between the timer and reading.
Count Mode Audio Mode will enable\disable click audio during a COUNT.
0 - Disabled -default selection (Mute icon will always be
illuminated in COUNT mode.)
1- Enabled
Ludlum Measurements, Inc. Page 2-10 July 2017
Model 3005 Gamma Survey Meter User’s Manual Section 2
Note:
Sigma audio is disabled in Count Mode. If Sigma Audio and
Count Mode Audio are enabled, click audio will be utilized in
Count Mode.
If a result in terms of activity is desired, the scaler count can also be in units
of "d" or disintegrations. But if the count units are chosen to be cpm or cps,
then the resulting answer is an averaged count rate over the time interval.
Similarly, if count units of Bq or dpm are chosen, the resulting answer is an
averaged disintegration rate.
Note:
If the user desires the instrument to show results in terms of
disintegrations/area (eg. dpm/100cm2 or Bq/cm2), then the
appropriate factor should be placed in the Efficiency
parameter.
Other choices are to have count mode units of R/h or Sv/h, in which case
the COUNT mode result is an averaged exposure or dose rate. But if count
mode units of R or Sv are chosen, the result is shown in accumulated
exposure or accumulated dose over the chosen count time. The following
tables lists the possibilities:
UNITS RESULT
c counts per count time
d disintegrations per count time
cpm, cps count rate averaged over the count time
dpm, Bq disintegration rate, averaged over the count time
R/h, Sv/h exposure or dose rate, averaged over the count time
R, Sv integrated exposure or dose over the count time
Ludlum Measurements, Inc. Page 2-11 July 2017
Model 3005 Gamma Survey Meter User’s Manual Section 2
In COUNT mode, operation depends on the current state of the Count
Timer.
When the Count Timer is Ready:
The display will show the Count Time.
Tapping the UNITS button will switch between the Primary and
Secondary Count Units. The newly selected Count Units will be
displayed for approximately one second, and the display will then
return to the Count Timer.
Long-pressing the ON/ACK button starts the Count Timer.
If other operational modes are available, tapping the MODE button
will move to the next available operational mode.
When the Count Timer is active:
The display will show either Count Time, both Count Time and
Counts, or just counts, depending on Count Display Mode.
Long-pressing the ON/ACK button will reset the Count Timer.
Tapping the UNITS button will switch between the Primary and
Secondary Count Units.
Click audio, if enabled, can be turned on and off by tapping the
Audio button.
If an alarm condition occurs, the ALARM display indicator will turn
on. Alarm audio will sound after the count is completed if the result
is over the alarm threshold. (If the count unit is an averaged rate, it is
possible for the ALARM icon to come on during the count, but if
the averaged rate falls below the alarm threshold by the end of the
count, no ALARM will be active.)
If other operational modes are available, tapping the MODE button
will cancel the current Count Timer and move to the next available
operational mode.
When the Count Timer has finished:
The display will show either the accumulated total for c, d, R, and
Sv, or the timed ratemeter average for cps, cpm, Bq, dpm, or the
average exposure or average dose in R/h and Sv/h.
Ludlum Measurements, Inc. Page 2-12 July 2017
Tapping the UNITS button will switch between the Primary and
Secondary Count Units.
Model 3005 Gamma Survey Meter User’s Manual Section 2
Long-pressing the ON/ACK button will reset the Count Timer.
If an alarm condition occurred during the Timed Count, a
continuous audio tone will sound, and the ALARM display indicator
will turn on. Tapping the ON/ACK button once will acknowledge
and turn off the continuous tone alarm audio. Long-pressing the
ON/ACK button will clear the alarm condition and reset the Count
Timer. Alarm audio will sound after the count is completed if the
result is over the alarm threshold. (If the count unit is an averaged
rate, it is possible for the ALARM icon to come on during the
count, but if the averaged rate falls below the alarm threshold by the
end of the count, no ALARM will be active.)
If other operational modes are available, tapping the MODE button
will move to the next available operational mode.

Entering Setup Mode
To enter setup mode, power down the Model 3005, then turn the unit back
ON. Following the display of the Firmware version, when the instrument has
begun normal operation, press the MODE button three times (within four
seconds) to enter Setup mode.
Note:
This process is different if you are in Sigma Mode, rather than in
the “click” Mode. While trying to enter Setup Mode from Sigma
Mode, once the screen displays the firmware number and then
begins counting down, press the Mode button three times as soon
as the countdown begins. Do not wait until the countdown is
complete, which will prevent you from getting into the Setup
Mode. There is no countdown for the “click” Mode.
Entry to Setup mode can be confirmed when the numeric portion of the display
shows P-1, indicating the first setup page is selected. If you simply wish to view
the parameters, select the desired Setup Page by tapping the MODE button.
Tap the UNITS button to advance through the parameters available on the
selected Setup Page. To return to normal operation, advance back to the Setup
Page selection, by long-pressing the UNITS button. Long-pressing the UNITS
button again will exit the menu. Holding the UNITS button for approximately 5
seconds will also exit from anywhere in the menu.
Note:
If the menu is not exited properly, any changes made will not be
saved.

SETUP PROTECT: The Model 3005 parameters can be protected from
unauthorized changes via the internal switch located on the Model 3005 circuit
board. To change the switch, open the battery compartment and remove the
batteries from the Model 3005. Next, loosen the six pan-head screws that fasten
the bottom cover.
Gently remove the bottom cover of the instrument. The DIP (dual in-line
position) switch should now be visible in the upper left-hand corner of the
circuit board.
To protect the Model 3005 from changes in Setup mode, slide DIP Switch 2
(the rightmost switch) to the ON (forward) position. If DIP Switch 2 is in the
OFF (back) position, changes are allowed in Setup mode. Once the DIP Switch
is set as desired, gently replace the back cover and the six pan-head screws.
Install the batteries, and replace the battery cover.
There are three different options for protect mode, which can be set through
Lumic Calibration Software. Locate the Parameter “Device Setup Prtct” in the
Others tab. Enter the desired option into the “Value” field.
- Normal: All Parameters are protected from change through the
device menu.
- Bypass Alarms: All Parameters except for Rate and Count Alarms
are protected from change through the device menu.
- Bypass Alarms Count: All Parameters except for Rate Alarms,
Count Alarms, and count time are protected from change through
the device menu.
Note that with the DIP Switch 2 in the ON position, Setup mode may be
entered and parameters viewed, but changes cannot be made.
DISPLAY BACKLIGHT ‘Continuous On’: The Model 3005 display
backlight can be set to remain on continuously during operation. Follow the
steps above for SETUP PROTECT, but use DIP Switch 1 for display
backlight selection. Setting DIP Switch 1 to the ON (forward) position will
configure the display backlight to remain on during operation. Set DIP Switch 1
to the OFF (back) position, and the display will be backlit only when light levels
are low.
Note:
Setting the display backlight for continuous-on operation can
result in reduced battery life. The backlight can be configured to
always be off as well through the device menu or Lumic
Calibration Software.

Setup Mode Operation
Setup Page Selection: Once the Model 3005 is in Setup mode, the Setup Page
selection will be displayed on the LCD, and the Page number will be blinking,
indicating it as the selected item. The number of available parameters per Setup
Page will be displayed using the graph – the number of segments indicating the
number of parameters. Tap the MODE button to choose the Setup Page. Once
the desired Setup Page is shown, tap the UNITS button to move to the first
parameter of that Setup Page. Long-pressing the UNITS button will exit the
menu.
Figure 11: Setup Page Selection display (showing page 4).
Long-pressing the Mode button, no matter what parameter is shown, will first
return the user back to the Page Selection screen and then exit if held for
approximately 5 seconds in total. Exiting can also be accomplished by one or
two individual long presses of the UNITS button, depending on where the user
is in the menu. (If on the page selection, only one press will exit, but if viewing
an individual parameter, two presses will be required.
The list on the following page lists the four setup pages and the parameters, in
order, on each page.

Normally the efficiency is used on a per detector basis or 4pi basis, i.e. the
efficiency of the detector is calculated by dividing the count rate received from a
source by the total disintegration rate of the source. When either dpm or Bq
units are chosen, the use of the 4pi efficiency allows the display of the source
size or activity on the Model 3005 display.
But if the user desires to have the Model 3005 show results in terms of
dpm/100 cm2, the user could manipulate the efficiency to produce this result by
multiplying the efficiency times the ratio of the detector area to 100 cm2. For
example, using a detector with an area of 15 cm2, if we start with 10% efficiency
to measure in dpm, then the parameter could be changed to 1.5% to measure in
dpm/100 cm2.
Or likewise for Bq/cm2, efficiency could be calculated as: efficiency = count
rate/disintegration rate*detector area (in cm2). For example, with the same
detector as above with an area of 15 cm2, and starting with an efficiency value of
15%, then the parameter could be changed to 225% to measure in Bq/cm2.
High Voltage (Default 800 Volts) - Tap ON/ACK to select the value to
adjust, and MODE to adjust the value. Value is in Volts. Available values are:
Ones Place (0-9)

Advanced Features
Dead Time Correction
All pulse counting detectors have a “dead time” in which the detector is unable
to register another event. In relatively low fields this is not an issue. However, as
the field strength approaches the high end of the detector’s range, dead time
causes the pulse rate to become non-linear with respect to the real radiation
field. Dead time correction is used to linearize the measurements, allowing a
wider linear response range for a given detector.
This instrument uses a second order dead time correction using the equation
where and are the dead time correction coefficients, is the
measured count rate, and is the corrected rate.
Dead time correction coefficients are configured through the device setup menu
or through Lumic Calibration software. Lumic Calibration software also includes a
wizard that will automate finding and setting the correct coefficients.
is represented in micro seconds (µs) on the device setup menu and in the
software. The equation must be calculated in terms of seconds (s) and must be
scaled appropriately. has more complex units and are not shown.
However, the representation of the coefficient on the setup menu and in
software do not require scaling.
Note:
Setting the to zero will disable the second order
correction, while setting to zero will disable both,

Units
Depending on the chosen display units, different features will affect value of the
reading. The following table lists the features that apply to each of the display
units.
R to Sv Conversion
The R to Sv conversion is a setting available in Lumic Calibration software. It
defines the conversion factor between R and Sv. Since the calibration
constant is directly tied to R (counts per R), calibrating Sv requires a correct
setting of both calibration constant and R to Sv conversion.
Example: A R to Sv conversion factor of 0.0106 will cause a reading of 10.6
mSv/h while in a 1 R/h field.
Software Calibration Tools
Lumic Calibration software includes wizards that will assist in calibrating and
plateauing detectors. After configuring the wizard for a specific detector, the
wizard will automate much of the data collection and calculation required for
calibration.

Model 3005 Gamma Survey Meter User’s Manual Section 5
Instrument Calibration
This instrument provides the ability to digitally enter a voltage for both high
voltage and threshold. As such, the instrument itself needs to be calibrated. This
happens at the factory when the instrument is built and should not require recalibration. However, if calibration is required (due to board rework, etc.), the
calibration settings are available in Lumic Calibration software.
Other Device Data
The following parameters on the instrument allow recording important device
information within the device:
Firmware Version: This is a read-only representation of the firmware version.
With a version of 4983XNyy.zzzz, the Xyy will show up on the device screen
during the power-on sequence and signifies the released version.
Device – Model Name: This should match the model name on the front face
of the instrument.
Device – Serial Number: This should match the serial number of the
instrument.
Detector – Model: This can store the model of the detector the instrument
was calibrated for.
Detector – Serial Number: This can store the serial number of the detector
the instrument was calibrated for.
Real-time Streaming
Lumic Calibration software and this instrument have the ability to stream data
from the instrument to a computer. The data can be viewed live inside software
or can be recorded to a file.
Multiple user-selected parameters can be streamed simultaneously including:

Datalogging
The datalogging feature of the Model 3005 allows the user to log radiation
readings with the use of a handle-mounted LOG button. Data can be
logged in any of the Model 3005’s operational modes (RATE, MAX, and
COUNT). Up to 1000 data points can be taken and stored internally.
Depending on the chosen Datalogging Mode, the user can quickly save
logged data using a single Location ID, or select from up to 250 stored
Location IDs. A Real Time Clock (RTC) is utilized to time and date stamp
each datalog entry.
The saved log data and stored location IDs can be viewed, downloaded, and
erased using the LMI Lumic software kit, which includes a USB cable.
Editing of datalogging parameters and RTC via setup mode on the
instrument is disabled.
Setup of the datalogging parameters is also done through the LMI Lumic
software. The advanced user or administrator can set:

Datalogging Operation – Mode 1
Datalogging Mode 1 will store the logged data using only the first Location ID
in the Location ID table.
When the LOG button is pressed, the current radiation reading and
other log data is saved along with the first Location ID in the format
specified in the Specifications at the end of this section.
In COUNT Mode:
o With a set count time, the LOG button is disabled until completion
of a Scaler count.
o For a continuous Scaler count (Scaler time is 0), the LOG button is
enabled at all times.
For approximately 2 seconds, the LCD will display the Datalog Table
index for the newly saved log data.
Figure 12: Display showing a Datalog Table index of 12.
After displaying the Datalog Table index, the instrument will return to
the previous mode of operation.
The Datalog Table is linear; once the table is full, no further writes will

If an attempt is made to write to a full Datalog Table, a beep will sound
and the maximum Datalog Table index (1.00 k) will be displayed for
about 2 seconds. The instrument will then return to the previous mode
of operation.

Datalogging Operation – Mode 2
Datalogging Mode 2 will allow the user to choose the Location ID (by Location
ID Table index) to store with the logged data.
When the LOG button is pressed, the current radiation readings and
other log data are temporarily stored.
In COUNT Mode: (Datalogging Mode 1 is always utilized in COUNT
Mode.)
o With a set count time, the LOG button is disabled until completion
of a Scaler count.
o For a continuous Scaler count (Scaler time is 0), the LOG button is
enabled at all times.
The LCD display will show a possible Location ID Table index for the
user. The index will be auto-incremented from the previously used
index.
Figure 13: Display showing a Location ID Table index of 36.
The ones digit of the index will be blinking, indicating a changeable
value. The user may then enter the preferred Location ID Table index
by tapping the ON/OFF (to select the digit) and MODE (to change
the value) buttons as in Setup mode.
Once the user has the preferred Location ID Table index entered, tap
the LOG button to save the log data.
For approximately 2 seconds, the LCD will display the Datalog Table
index for the newly saved log data (See Figure 12).
After displaying the Datalog Table index, the instrument will return to
the previous mode of operation.
The Datalog Table is linear; once the table is full, no further writes will
be allowed until the Datalog Table is erased.

Datalogging Operation – Mode 3
Data Logging Mode 3 will automatically record data log records using the
current location with the user settable auto log interval (settable to record every
1 to 1800 seconds).
When the Device is turned on and in RATE or MAX mode, the current
radiation reading and other log data is recorded at the set interval.
In SCALER Mode:
o Auto log will be paused and will only log at the completion of each
count.
o For a continuous Scaler count (Scaler time is 0), logs will be
recorded at auto log interval.
The Data Log Table is linear; once the table is full, no further writes will be
allowed until the Data Log Table is erased.
Note:
Tapping the LOG button will start a count and automatically log
the result. Long-pressing the LOG button during the count will
toggle the display between the timer and reading.

Software
Connecting to Software
Most Model 3005 instruments are sent with a standard 2-meter cable. (A 5meter cable can be provided if requested. However, any cable above 2 meters
may have issues with some USB-hubs/computers.)
In order to connect an instrument to the computer, please connect one end of
the USB cable to the instrument first, then the other end to the computer. Do
not connect both ends to the computer.
Please allow Windows® a moment to install the proper HID drivers for the
instrument before trying to use any software.
Note:
We recommend that you plug the USB cable into the back of your
PC that connects to your motherboard instead of a USB hub.
Note:
Some parameters may only be edited in software, such as the
backlight thresholds, COUNT Display Mode, COUNT Audio
Mode, and Setup prtct.
