Hi all
I've just got a 300E and i've worked out most of the operations of it and successfully downloaded the .bin data file.

If any one can help with the workflow from a .bin file to a nice looking graph or similar i'd really appreciate it.

I'm running the unit on an old WIN XP laptop and am MAC for everything else.

Any open source converters or programs or tutorials that can turn it from numbers to visual would be great.

Well i have worked out how to import to the software and then export as a CSV file.

Would be grateful if someone could point me in a direction to making a graph out of it though.

The graph normally is depending on the software you have.

I am using MS Excel spreadsheet software. It has graph wizard, you can just highlight the data you want to generate the graph and then click on the graph wizard icon.

Here are the steps:

1. open the .csv file from Excel software.
2. highlight the data columns you want to show on graph. here is the Date and CPM.
3. click on the Graph wizard icon
4. select line format
5. finish


Step 1: Load the CSV file

Step2: Highlight the data you wanted(Hold CTRL key and then click on column letter cell. Here are A,C columns.)

Step3: Select graph wizard from toolbar

Step4: Select line format from graph wizard

Thanks ZLM

This makes sense now i can see how it fits together.

I appreciate the screen shots
Will have a crack at it later today

ZLM or anyone else can you tell me the formula for converting the cpm into uS/h or another universal format.

I would like to be able to convert the graph into a format that a person can compare to a exposure standard.
Is it correct that using cpm is only relevant as a comparison to background CPM or a similar model Geiger counter.

The CPM to uS/h factor is depending on tube. You can find the factors from unit calibration value of menu.

DYHT,

In general, the defaults for the GQ units is 200CPM per 1.0uS/h. There are 3 ranges that are set proportional based on CPM. I use 152 per 1.0uS/h as I read that this is very close to most dosimeter measurements using similar tubes. I have a dosimeter which also uses the M4011 tube, and tests with Uranium samples, and long term background numbers are VERY close with both when I use this 152 CPM = 1.0uS/h. Anything in the 150-200 CPM per uS/h should be close enough for non-quantitative values.

uS/h is also dependant upon the type and energy of particles. Since the detector reads counts, it cannot specify the energy of the event as it triggers the response, so therefore any dosage rates are estimates.
The more I learn, the more I realize I do not know!
