Dud, when the Memorial Day
holiday is over I hope to get you on the phone to walk me through the command
change step to get the e-17 thing resolved, you know programming is not my
thing!

By the way, doesn't the
red MUTE light coming on tell you it's in alarm mode already?

I'm thinking I don't need
the possible fragile LED stack on top,? so a possibility for me is to
either just disconnect it and cap the hole or even install red and green LEDs
in the front cover like Geo's mod on the LENi conversions.?
It looks like the little
Gast pump might've been left in NM after all.? ?I have a Thomas
compressor,? like an airbrush type, that seems to output a goodly amount
of air.? I could set it in a plastic tote with the source and have it push
air into the SmartCAM,? or rig up a different box with the source in it
hooked to the monitor with a hose to pull air through it rather than
push.? But I think pushing air through would be better so it could cool
itself more effectively.?
I simply unplugged the
Sonalert! Also the LED stack.

I bet just a piece of tape
over it will go a long way.? Maybe a piece of thin cardboard.?
?I was lightly holding a thumb on it and that killed most of the
noise.?
I need to pull that little
Gast I have off the trailer,? see of it works,? then if it will pull
enough volume...

Run a fan across the pump...
If you turn the security key,? you can Mute the alarm with

Well, after 6+ hrs of running and taking 20 min data between the

to mute without getting into the command mode which requires getting even
closer to the Sonalert. We¡¯re going to need a bigger pump ?What do they

I think I¡¯ll go have a Dixie cup full of a fine Boxed Merlot and
grieve on the last Gasp of my poor $20 Gast pump.

THANKS Dud, great to know. Once I get it lined out, I'll start
comparing to the Femtotech.
how on earth did you figure that, was it in the manual?

Geo/Nick
To convert the wacko ?E-17
radon reading go to command mode with the Key get to the Radon tab and change
the 1e-16 to 186 which is the Po218 half life.. Bring up the Radon Acute
default
page to read Po 218 acute and Radon Acute. It will be in pCi/ml multiply by
1000 to get pCi/l.? I need to use Radon raw and Po raw but I still need to
figure
out how to do that.
I¡¯m running the RAD 7and
the SmartCAM together and the CAM showing 3.5 pCi/l ?while The RAD 7 is
averaging
4.0 pCi/l ?+- 2.1. Doing a manual calculation it always comes up low by a
factor 3 or so. That ma be due to not having all their corrections in there and
using acute cps

Geo,
What kind of solid samples

Most alpha samples are via liquid chem electro-deposited on steel disk, swipe

Peter,
The Smart Cam and usual
Radon sampling run around 32 L/min (1 cft/min).
Geo,
What kind of solid samples
are going to run? One needs to be very careful not to crap up the detector.
Most alpha samples are via liquid chem electro-deposited on steel disk, swipe
and air sample filters. Don¡¯t put a loose sample in there.

P, are you interested in
Alpha in air? That's fine, my intention was to do Alpha solid samples with my
6A head.

Need some advice.
What sort of airflow does the Eberline 6A expect ?
Or more useful is what sort of airflow should I use ? I don't know how make use
of the airflow control circuit in the 6A so I thought I might plumb the air
directly from a pump.
I have an old SKC air sampler pump. It sucks, but I can also get it to pump. It
goes up to 5l/min
4l/m @ 20" of back pressure.
