What is new in 4.08 firmware:

  1. Fixed background file load error that was happen after powering off the device
  2. Added more crystal sizes for correct energy compensated doserate (63x63mm, 10x40mm, 40x40mm)
  3. Added activity calculation geometries for 63x63, 40x40, 25x25 and 10x40 crystals
  4. Now you can set your crystal size by selecting correct type of the NaI(Tl) in activity menu, instead sending serial monitor command
  5. Added U-235 to the library. Improved auto-identification.
  6. Added sound notification when activity is calculated or when isotope detected
  7. Added service serial monitor command to set fast/slow scintillator May be useful if you are using slow CsI(Tl) scintillator with SiPM and external pulse shape amplifier.

All previous bug fix and updates from 4.01-4.07 are included in 4.08

You may need to recalibrate LLD, HLD, doserate factors, timestamp and energy scale after making firmware update

Isotope Library Include: Cs-137Ra-226Th-232, Bi-214, Ba-133Am-241Lu-177, K-40, Co-60, U-235

What is new in 4.06 software:

  1.  Optimized and faster peak detection
  2.  Fixed false positive detection triggering in some scenarios 
  3.  Improved Ba-133 and Lu-177 detection
  4.  Improved Cs-137 FWHM% resolution calculation
  5.  Added 3 minutes warning for warm-up period after power up
  6.  Added energy calibration hints with markers and energies list for the selected scheme

What is new in 4.05 software:

  1. Added second color theme for gamma spectrum with higher contrast. You can switch the spectrum color by making several turns of the encoder pointer toward 0keV direction. The encoder have to be in pointer control mode.
  2.  Added Th-232, Ba-133, Lu-177 isotopes to the auto-detection library
  3.  Added N.O.R.M. mix detection with mixed Ra-226 and Th-232
  4. Improved peak detection
  5. In scint.mode, the counter will make the event beep for every n=100 detected particle for large crystal or for every n=25 detected particle when small crystal is used. You can set crystal size through serial monitor command as described in the manual.

What is new in 4.04 software:

  1. Fixed software freeze caused by erratic energy calibration point
  2. Added detailed information on the boot screen with sound notification regarding wrong / missed energy calibration point

What is new in 4.03 software:

  1. Added FWHM% resolution measure for Cs-137 662keV peak, now you can roll the pointer over Cs-137 photopeak to read resolution.
  2. Added serial command to change LCD backlight PWM frequency because some LCD modules had failure with 25KHz PWM. Now the default PWM is 1KHz and you can change the frequency to any value in range  of 100Hz-25KHz
  3. Fixed bug with RN4871 bluetooth connection that caused spurious BLE commands during application connect.

What is new in 4.02 software:

  1. Added boot screen to allow viewing of all saved constants
  2. Added click sound for Geiger-Muller counter in scintillation mode
  3. Improved averaging procedure of Geiger-Muller CPS counter, now it show the correct result faster
  4. Added serial command to make a training data of isotopes for better and faster identification, see manual for details
  5. Added serial command to set crystal size, 51x51mm or 25x25mm
  6. Improved doserate energy compensation calculation
  7. Fixed bug of non correctly saved mean CPS to eeprom memory

What is new in 4.01 software:

  1. Better and faster Cs-137, Am-241 and Ra-226 RIID detection. Reduced the number of false detection events
  2. Added few BLE commands for calibration through smartphone terminal application, see user manual for more details
  3. Changed starting position of a channel pointer during energy calibration
  4. Minor changes in battery voltage monitoring and initial ADC configuration
