Jim, I think I will try to test my probes as you suggested. Again, how would
you do that ? I have a digital thermometer so would I have to get some water
hot and stick the thermometer probe and the CHT probe in there together and see
the difference in readings ? You mention grounding. Would I have to run a
ground wire from the CHT probe to the engine ? I remember when I purchased the
CHT kit the instructions mentioned that they could be off by as much as 75
degrees. Best to you, Bill of Georgia, N505WP, 601X-3300 w/dc and 60 plus hours

Hi All,
New to the forum. Thanks to Andy Silvester for bringing this new site to my attention
via the Yahoo Jabiru forum. Matronics looks very good on first inspection.
For information my Aircraft is the first Jabiru engined Tiposy Nipper and my little
donk is probably the oldest 2200 jab flying. It is engine number 17 ! :D
I am an Aircraft Engineer by trade and am fanatical about all things aircraft.I
am also a keen motorcyclist (Ducati 851) Other interests are model aircraft
and bird watching.
I would be most interested to make contact with any tipsy owners here in the south
of the UK
Kind Regards to all
Pat G-ASXI

When I calibrated my CHT's I set up about a pint of engine oil in a flat bottomed
pot. Heat was provided by a fondu warmer. I got the pot a 'Bed Bathe & Beyond
as a lidded canister for about $5. (My wife said OK to using the heater,
but not the matching pot.) This gives a reasonable temperature ramp and can
go to above boiling without agitation. I use a couple twists of safety wire
to keep the sensor and thermometer probes together. A heavy alligator clip provided
the ground.
The ground should go directly to the engine block. My sensor outputs shifted by
a factor of 3 between grounded and ungrounded tests. My sensors have a metal
mesh shield but it turns out is is just for abrasion, it was not grounded at
either end. The sensor also had a resistance to ground in the low milliohm range.
Obviously, in use the grounded configuration is the real world environment.

Hi Bruce, Send me your Email address and I'll ship you a couple photos.
Also the new Jabiru kits have ram air ducts that have the plug wires inside rather
then sticking through holes in the sides. Which configuration do you have.
I modified my old ones.
There have also been suggestions to add a exhaust elbow to the back of the ducts
to direct air at the mags in hot climates.
My address is jsto1@tampabay.rr.com
