  • Page 5: General Information

    General Information Product Description Section 1 General Information 1.1 Product Description Model 190 is a portable, battery-operated general-purpose survey meter for use with most scintillation and Geiger-Mueller (GM) radiation detector, proportional counting probes, and neutron probes. The design combines CMOS microprocessor technology, automatic range changing, and a Liquid Crystal Display (LCD) into an easy to use instrument.

  • Page 9: Theory Of Operation

    Theory of Operation General Circuit Description Section 2 Theory of Operation 2.1 General Circuit Description A block diagram of the circuit of the Model 190 is shown in Figure 2-1. The CMOS microprocessor is a TI 7000 series microprocessor, capable of addressing 64k bytes of memory. A 32k byte PROM contains the operating program and an 8k byte RAM provides storage for operational and data logging information.
  • Page 10 Victoreen 190 Operators Manual NOTE The counts per minute mode does not require a calibration adjustment because its time base is based on the highly accurate crystal clock of the microprocessor. All other displayed values (e.g., mR/h and Sv/h) can be derived from the counts per unit time value if a suitable calibration constant is used.
  • Page 11 Theory of Operation Operational Considerations and Applications Deadtime Effects The deadtime correction is limited to a maximum multiplier of 3.7 above 10 counts per minute (cpm) 5.4 from 10 to 10 cpm, and 1.6 from 10 to 10 cpm. Larger correction factors are permitted at higher count rates because of increased counting statistics.

    Victoreen 190 Operators Manual 2. Remove the battery compartment cover to gain access to the batteries. 3. Replace the batteries one at a time, observing proper polarity (refer to Figure 3-1) NOTE The unit may make beeping sounds while inserting the batteries.

  • Page 15: Adapter Module Installation/Replacement

    Operation Probe Holder Installation CAUTION Do not use the long screw (B), removed from the Model 190, in screw position (A). Doing so will damage the instrument. c. Use the .63” screw included with the kit to secure in screw hole (A). d.

  • Page 16: Power

    Victoreen 190 Operators Manual NOTE We recommend that the probe be secured to the mating probe adapter receptacle using heat shrink tubing. 4. Secure the Philips screw located on the top panel of the adapter. 3.6 Power The Model 190 is powered using four 9-volt alkaline batteries. The batteries (four) are housed in a separate compartment accessed from the instrument back panel.

  • Page 17: Internal Controls

    The Display Contrast Adjustment (RP1) is factory set for optimum viewing and Fluke Biomedical does not recommend that it be further adjusted. However; if the display contrast requires adjustment, turn RP1 to vary the angle of maximum contrast of the 16- character display.

Display Contrast (RP1) and +5 (RP2) Adjustment Locations Probe Adapter Module Adjustments The probe adapter module has high voltage (RP3), detector sensitivity (RP2), and detector jam current (RP1) adjustments located within it.

  • Page 19: High Voltage Adjustment

    Operation Internal Controls NOTE It may be necessary to tilt the adapter slightly when attempting to plug it into the unit. 6. Make the required voltage, threshold, and jam current adjustments as outlined in the following paragraphs. NOTE The Model 190 must be turned ON while making the probe adapter adjustments.

    Victoreen 190 Operators Manual XX is 24, 12, 6, or 3 seconds, corresponding to the newly selected response time. The Resp Time button may be pressed as necessary to scroll through and select the desired response time. The Resp Time button may be disabled via the Model 190-1A Communicator.
  • Page 23 Operation Changing the Operation Mode (Mode) All but one of the Operational Modes may be disabled via the Model 190-1A Communicator; one default mode must be enabled for the instrument to operate properly. Changing the Display Mode (Rate/Integ) The front panel Rate/Integ button toggles the alphanumeric display between the digitized rate value and the integrate value.

    If the display does not come on at all, replace the batteries and try again. If a partial display is visible, contact Fluke Biomedical at 440.248.9300 for further instructions. b. The display will blank and display the version number of the software in the alphanumeric display.
  • Page 25 In the event that the internal and external EEPROMS were not properly read, an error message(s) will be displayed (i.e., “INT EEPROM FAIL” and/or “EXT EEPROM FAIL”). Contact Fluke Biomedical at 440.248.9300 for further instructions. The instrument will then begin to operate in the selected mode.
  • Page 26 Victoreen 190 Operators Manual NOTE If the instrument is in the Integrate Mode, press and hold the RESP TIME button for three seconds. The integrate values should reset to zero without changing the response time. Press the AUDIO button to toggle on or off the click from the speaker associated with each count from the detector.
