    Study Notes

    Device Audio Settings

    • Backlight: Adjustable setting impacting visibility; OFF disables backlight.
    • Sigma Audio:
      • Enabled (ON) allows enhanced audio feedback.
      • Disabled (OFF) activates normal click audio.
      • Requires an 8-second background count for proper function.

      • Disabled in COUNT mode.
    • Dual Level Audio:
      • ON enables high and low audio options along with mute.
      • OFF restricts settings to high and mute.

    Datalogging and Alarm Settings

    • Datalogging Mode (Default 1): Displays current selection with values from 0-9 for ones, tens, and hundreds places; audio enabled only during setup.
    • Current Overload Threshold (Default 100):
      • Adjustable from 0-9 across ones, tens, hundreds places.
      • Setting to 0 disables the Current Overload Alarm.
      • Long press on DETECTOR button shows live current reading.

    Alarm Timers and Mode Settings

    • Loss of Count Alarm Time (Default 60 seconds):
      • Adjustable in seconds with similar value range (0-9).
      • Setting to 0 will disable the alarm.

    User Interface and Navigation

    • Model 3001 features multiple Setup Pages, each with distinct parameters, displayed graphically.
    • Tapping the MODE button allows users to cycle through Setup Pages.
    • The UNITS button accesses the first parameter and can exit menus with a long press.
    • Exiting is possible with one or two long presses, depending on the menu level.

    Setup Pages Overview

    • Parameters are organized into four main Setup Pages with specific settings for different models.
    • Each model has different calibration constants, efficiency levels, and thresholds pertinent to radiation detection.

    Parameter Settings

    • Setup Page P1 focuses on calibration constants, dead time corrections, and detection thresholds.

      • Calibration Constant (Mantissa and Exponent) varies by model, e.g., for Model 133-6, it's 122 and 04.
      • Dead Time Corrections have specific values (e.g., Correction 1 is 36 for Model 133-6).
      • Efficiency rates are differentiated: 100 for Alpha and 15 for Beta.

    • Setup Page P2 centers on Unit 1 settings, including rate, maximum display, and alarm configurations.

      • Example values for Rate/Max Mode Alarm include 5.00 mR/h for Model 133-6.
      • Minimum Display for Unit 1 sets to 0.00 for specific radiation units.

    • Setup Page P3 is dedicated to Unit 2 parameters, echoing settings from Unit 1.

      • Includes rates and display units, with maximum settings up to 999 kcpm.

    Additional Features

    • Response times, auto shutdown times, and audio modes are customizable settings across setups.
    • Datalogging and real-time clock features include month, day, year, hour, minute, and seconds settings to keep track of data consistently.

    Alarm Settings

    • Multiple alarm configurations for Units 1 and 2 are customizable to enhance user awareness.
    • Overload thresholds and loss of count alarms are set, ensuring adequate monitoring during operation.

    Customization and Control

    • The Model 3001 allows for specific configurations tailored to laboratory or field conditions, enhancing usability in various environments.
    • Auto shutdown can be disabled for continuous operation where necessary, such as in prolonged surveys.
