Hello all, unsure if this is a good place to discuss this or not, but I can't find many Geiger counter forums.
I recently got myself a CDV 700, and while I want to get it professionally calibrated it's a bit expensive at this time (a tad over $100, just $35 less than I paid not including shipping).
Anyways, I have heard that the test source is either supposed to measure at 2 exactly, or between two and 3, however this one reads up to 4 easily, and can even max out the meter (all on the 10x range btw) if I position it right.
Now, if anything it should read lower due to the half life of depleted uranium, no?
Just wondering if I should "calibrate" it so that it reads roughly 2 or so, or if it might be fine, and they used the alternative to depleted uranium and somehow it has gained radioactivity?
Anyways, just hoping for it to be roughly accurate till I have the spare cash to get it calibrated. It is understandable that it is out of cal though, since the last calibration was in 1984

Oh, forgot to mention by following the above noted instructions the midrange best number for calibration was 10 this time first photo - for the above pictures. The first time I did it the midrange best number was -8
