I need to reload Factory setting to my GMC-300E, which is available in:
Init Setup/Factory Reset
Can you please inform me how can I navigate to Init Setup?

Hello Ullix,
Thank you very much for your so precise answer !
I install phonon on my laptop and now all is pretty...
sudo apt-get install python3-pyqt4.phonon
Now I'll test a gps logger and maybe will play with openradiation.

Have a nice day !

There is a simple factor between CPM and µSv/h:
Dose Rate [µSv/h] = CPM * 0.0065
An advanced Python Program GeigerLog is available here:
https://sourceforge.net/projects/geigerlog/
The GeigerLog manual explains the relationship of CPM and µSv/h in more detail.

Hello,
I have a gmc-300E and I get CPM on laptop by USB link with a Python program. I don't know how to transform these CPM to µSv/h.
I can read both the µSv/h value and CPM value on the device display but I can only get CPM on the laptop.
Is it a linear formula ? Sv/h = k*CPM. what is k value ?
Is there a false time correction ? Sv/h = k* CPM / (1 - a*CPM)
Is there a temperature coefficient ?
What is the tube reference ?
Thank you a lot for your help !

The program I write is this one, but you must indent inside the test if..else: and inside the while: loop.
import serial, time
ser = serial.Serial("/dev/ttyUSB0", 57600)
ser.write (("<<GETVER>>"+chr(0)).encode(encoding='utf-8'))
time.sleep(1)
print ((str(ser.read_all ()))[2:-1])
while True :
ser.write (("<<GETCPM>>"+chr(0)).encode(encoding='utf-8'))
time.sleep(1)
res = ser.read_all ()
if len (res) == 2 :
print (time.ctime() + " , " + str(res[0]*256+res[1]) + "CPM")
else :
print (time.ctime() + " , ERROR")
time.sleep(59)
