[comp.sys.handhelds] Real-time process monitoring

mark@hpcpbla.HP.COM (Mark Simms) (06/29/90)

A year ago I would have said the answer is simple, provided you don't
want too much performance out of the thing.

An HP41CX will give you a portable real time controller capable of
making a measurement about once a second.  A number of multimeters can
be used, from the CMT-300 3 digit multimeter to HP's own 3468A 5 digit
multimeter.  (The last requires an HP-IL interface in the HP41CX.)
Data can be stored in non-volatile RAM in the HP41CX or on cassette
drives or disc drives.  All of this is battery powered and small
enough to fit in a briefcase.

Unfortunately, about a year ago HP stopped producing the HP41CX.  You
may still be able to get one from somewhere.  EduCALC is your best
bet.  They will also have details of other parts of the system that
may be useful.  Their address follows.

	EduCALC Mail Store
	27953 Cabot Road
	Laguna Niguel
	CA 92677
	USA

They may be able to suggest any alternatives if they cannot still
supply an HP41CX.

Hal,

Try these two places.

DGH Corporation
P.O. Box 5638
Manchester NH 03108
(603)622-0452

Omega Engineering, Inc.
One Omega Drive, Box 4047
Stamford, CT 06907
(800)872-9436

Ask each of them about their D1000, D2000, D3000 and D4000 series of
signal conditioning modules.  DGH makes them; Omega and others OEM them.
I think you'll find they're just what you need.

I emailed you a short summary of the modules.
