General Description Windows-Based Software No Parity, 8 Data Bits, 1 Stop Bit) is displayed for information only. A second editable field enables/disables communications diagnostics. Editing this field will clear the error counters. The third region of the screen presents the H.V. Plateau Starting Voltage, The H.V. Plateau Step Size (volts), and information fields for up to four calibration sources. When editing the H.V. Plateau Starting Voltage and Step Size, the operator should keep in mind that there will be nine voltage settings used and that the maximum high voltage should not exceed 1500 volts. The calibration source information consists of 5 fields for each source. The first field, “Source ID”, can hold up to 16 alpha-numeric characters. The second field is Calibration Date, to be entered in MM/DD/YY format. The third field is Half Life (years). The fourth field is Activity (mCi). The fifth field is not editable; it is the Decay Corrected Activity (mCi). The decay corrected activity is calculated using the date from the DOS system clock. It is crucial that the correct date be available at boot up either through a resident, real time clock, or through operator input. Note Thermo Fisher Scientific uses the information found in ICRP Publication No. 38, Radionuclide Transformations, and provides the following two half lives for reference: 137 Cs -- 30.0 years ▲ 60 Co -- 5.27 years ▲ Reports Quit The “Reports” routine prints out the parameter files and calibration reports stored on disk. Each time the routine is invoked, the operator is prompted to enter the portal number. This number must correspond to the address of the portal set on the Master/Annunciator PC board, which is read by the program at connect time. For information about the switch settings refer to the Switch Setting drawing, No. 11468-C109 in Appendix C: “Drawings” of this manual. “Quit” is invoked to exit the PM-7 calibration/configuration program. When the command is executed the operator is prompted with the message “Return to DOS?”. An affirmative response will leave the program. A negative response will return the operator to the main menu. 5-10 _Personnel Monitor -7 Techical Guide Thermo Fisher Scientific
Chapter 6 Maintenance Preventative Maintenance Keep the instrument clean and dry. Remove any accumulations of dust from the electronic components. Run the diagnostics routines in the PM-7 Calibration/Configuration program on a regular basis to verify proper operation. The incandescent bulbs have a life rating of 50,000 hours. Replace no less frequently than once every five years. The battery has a rated life in float charge operation of four years. Replace at least once every four years. Setting Low Voltage Batteries Calibration The low voltage power supply is located in the enclosure at the top of the portal and is accessed from above. The output voltage should be 6.75 to 6.90 Vdc. The output voltage is adjusted with a potentiometer located at the front of the power supply in the vicinity of the terminal strip. Access to the potentiometer can be improved by separating the power supply from the main chassis of the PM-7 and raising it a few inches from the chassis. The output voltage should be adjusted under load (PM-7 running) with the batteries disconnected. Many of Eberline's instruments contain batteries, alkaline, carbon, lead or lithium. All batteries contain small amounts of heavy metals and other hazardous materials and must be disposed of properly. DO NOT mutilate, puncture, or dispose of batteries in fire. Alkaline, carbon and lithium batteries are NOT rechargeable. Thermo Fisher Scientific recommends taking all batteries to an appropriate recycling center for disposal. Calibration is performed with the PM-7 Calibration/Configuration program running on the calibration computer. Operation of the program is explained in Chapter 5: “PC-Based Calibration/Configuration Program”. Familiarize yourself with the program operation procedure before proceeding. Connect the calibration computer to the PM-7, boot the computer, invoke the PM-7 program, enter the correct password and connect to the portal. Enter the “Calibrate” submenu.
