Page 9: Introduction
5.1 cm (2 in.) diameter and up to 0.64 cm (0.25 in.) depth. The Model 3030P is powered by a universal input wall-mount power supply, or may be powered from four “D” cell batteries. The instrument features a built-in detector power supply, adjustable count time periods, and click-per- event audio with adjustable volume. - Page 10 Avoid touching the tray while counting, and place the instrument on a stable surface. Caution! The Model 3030P is sensitive to excessive shock, which can cause permanent damage to the detector. This can happen if the instrument is dropped or if it's not protected during shipping.

Model 3030P Technical Manual Section 2 Select Finish to complete the software setup. Start-up Before using the instrument for the very first time, determine whether or not a computer interface is desired. If the computer interface is desired, please return to the previous subsection, “Software Installation,” before continuing, and then connect the instrument to the computer using the USB cable provided. - Page 19 Model 3030P Technical Manual Section 2 If using the computer interface, start the interface program from the appropriate directory/shortcut and set the desired operating parameters described in detail in Section 6 of this manual. Also, if desired, perform a QC check. See Section 6 of this manual for further details on QC check.

Cleaning Instructions and Precautions The Model 3030P Alpha-Beta Sample Counter may be cleaned externally with a damp cloth, using only water as the wetting agent. Do not immerse the instrument in any liquid. Observe the following precautions when cleaning: 1. -
Page 26: Warning Markings And Symbols
If the wrong power converter is used, the instrument and/or power converter could be damaged. The Model 3030P Alpha-Beta Sample Counter is marked with the following symbols: DIRECT CURRENT (DC) (IEC 417, No. 5032) - designates an input receptacle that accommodates a power cord intended for connection to DC voltages. -

Model 3030P Technical Manual Section 5 Warning! The operator is strongly cautioned to take the following precautions to avoid contact with internal hazardous live parts that are accessible using a tool: 1. Turn the instrument power and disconnect the power cord. -
Page 28: Calibration And Maintenance
Calibration Procedure Perform mechanical checks, such as switch function and illumination of digital readouts. Connect the Model 3030P to the computer and load the default settings. Ensure that both dipswitches, located on the main board, are in the position. - Page 29 βSourceCα =β source count in α channel BackCα = background count in α channel βNetCβ = Net β source count in β channel For the alpha/beta PIPS™ detector in the 3030P, achievable 4π efficiencies are approximately: 15% for 36% for...

Page 30: Maintenance
Recalibration should be accomplished after any maintenance or adjustment has been performed on the instrument. Ludlum Measurements recommends recalibration at intervals no greater than one year. Local regulations may have precedence over this recommendation. - Page 31 Model 3030P Technical Manual Section 6 A PIPS™ detector can be cleaned to remove radioactive contamination in the form of dust/dirt, oil, oil films, fingerprints, or dust particles on the surface. Recoil nuclei contamination can be removed to some extent by cleaning as well, but recoil nuclei can become embedded in the varnish surface and cannot be completely removed by cleaning.
- Page 32 To clean the PIPS™ detector, it must be first removed from the 3030P detector assembly. If the detector only needs inspection and possible cleaning, this may be done without removing the entire shielding/cylindrical mounting assembly from the chassis.
- Page 33 Model 3030P Technical Manual Section 6 The connector assembly is wire-tied to the left bottom front support post of the circuit board (as viewed from the right photo above). Cut this wire tie and unplug the two connectors from the circuit board.
- Page 34 If the detector mounting and O-ring has contamination, an alternative and more extensive process of removing the entire cylindrical detector assembly and shield from the Model 3030P chassis can also be accomplished. Following the same steps above, power down and remove the cover of the Model 3030P and remove the connectors and the lead shield bracket.
- Page 35 Model 3030P Technical Manual Section 6 Note: Do not forget to secure the cover plate and re-install the four screws and lock washers in the cover plate. This will allow the whole detector and shielding assembly to be turned upside-down for inspection and cleaning.
- Page 36 Model 3030P Technical Manual Section 6 The assembly with the shield may be placed upsid- down and the detector cleaned as described previously or as seen in the PIPS cleaning video. Re- assembly of the system entails reversing the above steps with the replacement of the detector back into the housing, as well as the replacement of the foam pucks and securing the assemblies back into place.

Page 37: Computer Software
Section 7 Section Computer Software he Model 3030P Control Software allows the user to set all parameters, view QC check settings, change alpha and beta window and threshold values, perform MDA (Minimum Detectable Activity), and retrieve the sample data saved to the logging memory. - Page 38 Model 3030P Technical Manual Section 7 The following parameters require a password: Calibration Date, Date, Time, Background Subtract On/Off, Alpha Background Subtract, Beta Background Subtract, Alpha Efficiency, Beta Efficiency, Crosstalk On/Off, Alpha Crosstalk, and Beta Crosstalk. The password operation can be enabled in the Parameters menu. Selecting the Password Protect menu item will enable password protection.
-
Page 39: Parameters
Model 3030P Technical Manual Section 7 The user is prompted for the password when clicking on the Update button after changing any of the password protected parameters. If the password given is correct, the parameters are changed and the instrument is updated. - Page 40 DPM (disintegrations per minute). By knowing what the efficiency is for alpha and beta particles, the Model 3030P is able to divide measurements by the known efficiency and display in DPM. The DPM mode may be easier for users since many regulations and limits are expressed in terms of DPM.
- Page 41 Model 3030P Technical Manual Section 7 In DPM mode, the counts are adjusted for count time and efficiency. For example: Count Time = 0.1 minutes (6 seconds) Efficiency = 25% Input = 1000 DPM CPM = 250 counts per minute (no background subtract or crosstalk...

Page 42: Qc Check
Section 7 QC Check The Ludlum Model 3030P has a QC Check function that allows the user to determine if the instrument is operating within predetermined limits. This function is optional and does not have to be enabled. There is also an option to update the background every 24 hours. - Page 43 Model 3030P Technical Manual Section 7 3. The instrument counts background (no source inside the tray) and receives results that are within the upper and lower limits specified. QC Off/Normal QC/Background Update Only : If enabled, 24 hours after the last QC check the QC LED turns on and a QC check must be run before the normal operation can resume.

Page 47: Data Logging
Technical Manual Section 7 Data Logging The Model 3030P can store 600 samples in its data logging memory. The following fields are stored with each sample: time, date, alpha reading, beta reading, count time, count mode, and user-defined comment. Logging Mode : The choices are either Off, Log All, or Log QC only. -
Page 48: Spectral Information
When the count time is chosen, the time switch on the instrument needs to be set to “PC.” If the 3030P is not set to PC control, the spectral data acquisition time is determined by the setting on the 3030P. -
