STATEMENT OF WARRANTY Ludlum Measurements, Inc. warrants the products covered in this manual to be free of de- fects due to workmanship, material, and design for a period of twelve months from the date of delivery. The calibration of a product is warranted to be within its specified accuracy lim- its at the time of shipment.
NTRODUCTION The Model 3003 and Model 3003i are ergonomic, lightweight instrument which can be used for radiation survey purposes. The Model 3003 features the ability to measure radiation in count rate, exposure rate/dose, activity rate, integrated exposure/dose, time-averaged rates, and scaler counts. It supports up to four external radiation detectors to detect alpha, beta, gamma, or neutron radiation.

"find" something. They can simply listen for multiple beeps. Setup of the instrument is accomplished through the front-panel buttons, or through Lumic 2.0 software available from Ludlum Measurements. Front-panel setup can be disabled via the internal switch on the Model 3003 in order to pro- tect settings from inadvertent changes.
ETTING TARTED 2.1 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 de- tectors (if applicable).
Instead, use the following table to determine which main processor board is installed in the instrument: • 1 tick - 5519-001 • 2 ticks - 5519-305 • 3 ticks - 5519-812 Ludlum Measurements, Inc.
2.3. TURNING THE INSTRUMENT ON Use the following table to determine which high-voltage board is installed in the instrument (if any): • 1 tick - 5519-187 • 2 ticks - 5519-817 A revision level of 0 indicates that the board is not installed or detected. Next, the instrument displays the firmware version.
This is a com- mon occurrence after installing new batteries into the instrument after an extended period without batteries (typically greater than 15 minutes). Figure 2.6: Instrument Date Reset (Audio Alarm) Ludlum Measurements, Inc.
2.4. INSTRUMENT DIAGNOSTICS To acknowledge this condition, a short press of the ACK/RST button will silence the alarm, clear the screen, and resume normal instrument operation. A ’FAULT’ message will remain on the screen as a reminder until the instrument power is cycled. Time and date are necessary when the instrument is configured for datalogging as each log record is time/date stamped.
If desired, multiple readings may be taken at different distances and/or with different sources so that other scales are checked. Example of a Check Source reading: Check Source # Rate Units Once this procedure has been completed, the instrument is ready for use. Ludlum Measurements, Inc.
2.6. SIGMA AUDIO 2.6 Sigma Audio The Ludlum Model 3003 has the standard "click" audio that is widely used by radiation in- struments; however, it also has a Sigma Audio mode that can be enabled to change the audio sound. This mode is useful for scintillation detectors because their high count rate makes the "click"...
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 Ludlum Measurements, Inc.
2.8. INSTRUMENT USE AND CONTROLS the OVERLOAD and ALARM icons, three dashes will be displayed in place of the numerical values, and an alarm tone will sound. Once the detector current goes below the threshold, the Model 3003 will return to normal operation.

Long Press (press and release after two beeps): • Currently has no effect. Extra-Long Press (press and release after three beeps): • Enables/disables the Auxiliary Communications as indicated by a wifi symbol on the top of the LCD screen. Ludlum Measurements, Inc.
2.8. INSTRUMENT USE AND CONTROLS Figure 2.13: WiFi Symbol 2.8.3 DETECTOR Button: The Detector button’s primary function is to switch between available enabled detectors. Short Press (press and release after one beep): • Used to select the active detector, as evidenced by the corresponding DET1, DET2, DET3, or DET4 LED.
Short Press (press and release after one beep): • In RATE mode, it will log the current rate reading if datalogging is enabled. • In MAX mode, it will log the current MAX value if datalogging is enabled. Ludlum Measurements, Inc.
2.8. INSTRUMENT USE AND CONTROLS • In COUNT mode, it will: – If COUNT mode is ready: Initiate a count. Upon completion, the result will be logged if datalogging is enabled. – If COUNT mode is in progress: Button has no effect. –...
The word MAX will be displayed when in MAX mode. A short press of the UNITS button will switch the displayed value between the Primary and Secondary Units. If the detector is configured for alpha/beta, the UNITS button will switch Ludlum Measurements, Inc.
2.11. COUNT MODE OPERATION between alpha and beta. A combination of alpha and beta (ex. alpha + beta) can be viewed if Unit 3 is enabled for the detector. A short press of the ON/AUD button will cycle through the “click” audio volume levels. When Sigma Audio is enabled, a short press of the ON/AUD will toggle the Sigma Audio volume levels.

Similarly, if count units of Bq or dpm are chosen, the resulting answer is an averaged disintegration rate. Ludlum Measurements, Inc.
Page 33
2.11. COUNT MODE OPERATION If the user desires the instrument to show results in terms of disintegra- tions/area (eg. dpm/100 cm ), then the instrument should be configured for dpm and the appropriate factor should be placed in the Efficiency parameter. Bq/cm will use the stored detector active area and perform the calculations internally so no manipulation of the efficiency is needed.

ATALOGGING The datalogging feature of the Model 3003, accessible through the use of the optional Lumic Datalogger software kit, 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 3003’s operational modes (RATE, MAX, and COUNT).
– 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. Ludlum Measurements, Inc.
5.3. DATALOGGING OPERATION – MODE 3 Figure 5.2: Displaying Datalog Location ID Table Index of 36 • The number will be blinking, indicating a changeable value. The user may then enter the preferred Location ID Table index by a short press of the PRG (to increment the value) or ACK/RST (to decrement the value) buttons as in Setup mode.
OFTWARE 6.1 Connecting to Lumic 2.0 Calibration/Configuration Software The Lumic 2.0 Calibration/Configuration software is sent with a standard two-meter cable. (A five-meter cable can be provided if requested. However, any cable longer than two meters may have issues with some USB hubs and computers, typically laptops.) To connect an instrument to the computer, please connect one end of the USB cable to the instrument first, and then the other end to the computer.
DVANCED EATURES 7.1 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.
However, if calibration is required (due to board rework, etc.) the calibration settings are available in Lumic Calibra- tion software. 7.6 Other Device Data The following parameters on the instrument allow recording import device information within the device: Ludlum Measurements, Inc.
