- 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
-

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.
