Installing Rad Pro on the Bosean FS-600/FS-1000

Supplies

To install Rad Pro on your Bosean FS-600 or FS-1000 Geiger counter, you will need the following tools and components:

Step 1: Open the device

Bosean FS-600 circuit board

Follow these steps to start installing Rad Pro:

  • Turn off the device.
  • Remove the battery cover and batteries.
  • Remove the screws holding the back case and open the device.

The board should look like in the photo above. If it does not, you may have a different hardware revision. In this case, Rad Pro may not function properly.

If your board looks different and Rad Pro does not work, create an issue.

Step 2: Connect the programmer

Now, follow these steps:

  • Optional: Solder the 4-pin header to the SWD pads of the board.
  • If you use Windows, install the ST-LINK driver.
  • Connect the ST-LINK V2 device to the SWD pads. The pins, from left to right, are:
    • +3.3V
    • SWDIO
    • SWCLK
    • GND

Make sure the electrical connections are correct. You may break your device if the connections are not correct.

Step 3: Flash the firmware

Now, download the latest radpro-flashtool from the Rad Pro releases.

  • To install from Windows, go to the bosean folder and start bosean-[device]-[type].bat.
  • To install from macOS or Linux, go to the bosean folder and start bosean-[device]-[type].sh.

[device] is the type of your device: fs600 or fs1000.

[type] is the type of installation: install or update. Note that not all releases support updating.

The installation will automatically create a backup of the original firmware in the backup folder, so you can recover your device if something goes wrong. Make sure you keep the backups safe, so you can always return to the original firmware. To flash a backup, drag it onto bosean-[device]-install.bat (Windows) or bosean-[device]-install.sh (macOS/Linux).

Step 4: Configure your device

Start your device and go to Rad Pro's settings, select “Geiger tube”, “HV Profile” and choose an appropriate HV profile: “Energy-saving” is best for measuring background levels of radiation, while “Accuracy” consumes more power but allows measurement of higher levels of radiation; “Factory default” is the profile from the original firmware and consumes considerably more power.

To establish a USB data connection under Windows, install the CH340 driver.

Last, read the user's manual for learning how to use Rad Pro, and the ionizing radiation field guide for learning more about ionizing radiation.

Step 5: Get involved

If you like Rad Pro, consider watching the project to get notified when new releases are out. Also, show your support by starring the project on GitHub. And don't forget to read the keyboard mapping table below!

Hardware-specific notes

On the FS-600, the keys are mapped as follows:

  • Power on/off: long hold of the ok/power key.
  • Switch measurement mode: the up and down keys.
  • Switch measurement secondary view: the left/back.
  • Reset measurement/dismiss alarm: long hold of the left/back key.
  • Put display to sleep (measurement view only): the ok/power key.
  • Enter settings: the right/settings key.
  • Go up/down: the up and down keys.
  • Select option: the ok/power or right/settings key.
  • Go back: the left/back key.
  • Toggle pulses sound: long hold of the menu/ok key.
  • Toggle lock mode: long hold of the ok/power and left/back keys.

On the FS-1000, the keys are mapped as follows:

  • Power on/off: long hold of the set/power key.
  • Switch measurement mode: the mode key.
  • Switch measurement secondary view: the set/power key.
  • Reset measurement/dismiss alarm: long hold of the mode key.
  • Enter settings: short hold of the set/power key.
  • Go up/down: the mode and set/power key.
  • Select option: short hold of the set/power key.
  • Go back: short hold of the mode key.
  • Toggle lock mode: long hold of the set/power and mode keys.

Not all devices support the pulse LED.

To establish a USB data connection, connect your FS-600 or FS-1000 to a computer using a USB data cable.

On the FS-600 and FS-1000, Rad Pro can store up to 89100 data points. At normal radiation levels (20 cpm), this allows for 1857 days of data at 60-minute intervals, 309 days at 10-minute intervals, 61 days at 1-minute intervals, 10 days at 10-second intervals and 24 hours at 1-second intervals.

The FS-600 and FS-1000 include two Zener diodes that limit the maximum voltage to 440 V (nominal).

The FS-600 and FS-1000 HV profile settings are:

  • Factory default: 40 kHz frequency and 50% duty cycle.
  • Accuracy: 2.5 kHz frequency and 6.5% duty cycle.
  • Energy-saving: 2.5 kHz frequency and 3.0% duty cycle.
