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.
The Model 3005 is an ergonomic, lightweight instrument which can be used for measure- ments of gamma radiation levels up to 50.0 mSv/h (5.00 R/hr). The Model 3005 features the ability to measure radiation in count rate, exposure rate/dose, activity rate, time-averaged rates, and scaler counts.

It is located near the left handle base. If a headphone jack is not in use, the Model 3005 may optionally be provided with an RS- 232 serial output for connection to PC or other electronic device. For more advanced use:...
Check individual item serial numbers and ensure calibration certificates match between instruments and de- tectors (if applicable). The Model 3005 serial number is located on a label on the front side of the unit.
Instead, use the following table to determine which main processor board is installed in the instrument: • 1 tick - 5498-612 • 2 ticks - 5519-091 • 3 ticks - 5519-779 Ludlum Measurements, Inc.
2.3. INSTRUMENT OPERATIONAL TEST The instrument then displays the battery voltage. Please see Figure below. Figure 2.3: Battery Voltage Display The instrument then displays the number of stored records if datalogging is enabled. Please refer to the figure below. Figure 2.4: Startup Display Showing 189 Stored Data Records The instrument will then move to normal operation, displaying the current rate for the Pri- mary units (factory default: mR/h).
fixed tone audio and a steady ALARM icon when a predetermined fixed alarm level is exceeded. 2.5 Detector Failure Diagnostics Note that the Model 3005 has its own diagnostic tests to ensure that the detector is function- ing correctly. 2.5.1 Detector Loss of Count If the detector stops detecting radiation for a settable number of seconds, the Model 3005 will flash the minimum display value to indicate which units have been affected by the loss...
Figure 2.6: Detector Over Range (Display Will Flash) 2.5.3 Detector Overload As another diagnostic test, the Model 3005 monitors the HV supply’s detector current. A cur- rent overload threshold can be set via Setup Mode or Lumic Software. (A setting of 0 disables this alarm.) In general, this alarm setting can be used to detect when there is some detec-...
With four front-panel buttons and one handle button (as seen in front-panel drawing in front of manual), the Ludlum Model 3005 offers many features in a small package. Each button may be pressed and held for a predetermined length of time, signified by instrument beeps, to access unique instrument features.
2.6. INSTRUMENT USE AND CONTROLS • During normal operation, it will acknowledge/silence alarms in any mode of opera- tion. • Change Log Location selected position (If data logging mode 2 is enabled). • Will move selection position in the device menu. Long Press (press and release after one beep): •...
• Device Menu: When viewing the detector current overload set point, this will switch the display between the live current reading and the set point value. 2.6.4 MODE Button: The Mode button’s primary function is to switch between available enabled modes. Short Press (press and release before one beep): Ludlum Measurements, Inc.
2.6. INSTRUMENT USE AND CONTROLS • During instrument initialization and within 4 seconds after the power-up screen, three short presses of the MODE button will place the instrument into setup mode. Once the instrument is displaying normal operation, and 4 seconds have passed, the button can be used to advance to the next available mode.
If other operational modes are available, a short press of the MODE button will move to the next available operational mode. By default, a short press of the LOG button, if datalogging is enabled, will log the currently displayed rate. Figure 2.8: RATE Mode Displaying Background Radiation Rate Ludlum Measurements, Inc.
2.8. MAX MODE OPERATION 2.8 MAX Mode Operation While in MAX mode, the highest detected count rate (since MAX mode was selected) is dis- played. 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.

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 Ludlum Measurements, Inc.
2.9. COUNT MODE OPERATION result is shown in accumulated exposure or accumulated dose over the chosen count time. The following tables lists the possibilities: UNITS RESULT counts per count time 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...

CHAPTER 4. SETUP MODE SETUP PROTECT: By default, the Model 3005 is shipped with DIP Switch 2 in the OFF (back) position and all available Model 3005 parameters may be modified in Setup mode. To pro- tected the Model 3005 from changes in Setup mode, open the instrument, by removing the six screws on the bottom of the can, and slide DIP Switch 2 (the rightmost switch) to the ON (forward) position to activate Setup Protect Mode.
4.4. SETUP MODE OPERATION 4.4 Setup Mode Operation Once the Model 3005 is in Setup mode, setup page selection will be displayed on the LCD and the Page number will be blinking indicating it as the selected item.

OFTWARE 6.1 Connecting to Software The Model 3005 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.
Firmware Version: This is a read-only presentation of the firmware version. With a firmware version of F.x.y.zzzz, the F.x.y will show up on the device screen during the power-on sequence and signifies the released version. Ludlum Measurements, Inc.
