The attachment point should have been provided by the engine manufacture. Its a
Jabiru 3300 engine! There they no attach point. The manufacture is using the
RING mount thermocouples
Does the voltmeter have a specific scale for temperature and it is set up for K
type probes? YES and YES. Scale is Centigrade
Also what is ACT? Actual readings from Voltmeter
Grounded.

AHhhhh Got-cha Rick:
I would NOT use the Ring thermocouples under the spark plugs. As I
mentioned they are poor in two ways:
1 - The temps always read high and
2 - They cause the spark plugs to run hot.
Let's add a third reason-
3 - Because of location the readings are not usable for comparison between
planes as a reference. EVEN with a plane also equipped with ring probes.
Just way too much of a difference in readings.
You mentioned the other unit you used to compare temps; were were those
probes attached?
OK, since you are using Grounded probes they are usually a bit less
expensive. And they are more common.
Make sure ALL the probes use the SAME colored wire for the Ground
connection. Usually it is the WHITE wire, the RED one is the HOT and is
kept above Ground.
Go with the other unit and those readings. You have already noted
the variance between them is less.
Too many variables equals too many problems.
