I know someone on CG rents a Scace device with Fluke meter, maybe rent that and try again? Is the Fuji setup correctly to use the thermocouple?
Do you have the Linea AV? If so, and I'm not sure how much this can affect the temps, the flowmeter uses the brew temp water and there is some cooling of the water as it flows along this path. Maybe that's causing some cooling?
I have the EP kit, set up on a 2AV. At first thought I figured it was just my styrofoam setup, but I did a similar test on my Anita, and it turned up results or close results based on my cooling flush technique. I admit this is not the best way to test, but it should get in the general range, not 10 degrees different. Fuji is set up as per EP's instructions, and the massive amounts of reading on here, so I'm fairly certain It's correct.
I know the 2av thing will give me a much greater offset, but Greg Scace has his set at around 205, and gives him about 200 at the group. (same machine as him)
Thanks Dan, this is on my list of things to try, I just want to see if I can get it in "range" before I spend the $$ on this, which I'm sure I will to fine tune it.
Arpi wrote:Your pid is probably doing an excellent job. What happens is that the pid sensor is connected to the boiler not the brew head. There is a difference in temperature between those two. You can adjust the offset by setting a variable called "SV offset". You need to download the manual of the pid and look at the instructions on how to change it.
I agree with this, but I also think that it is a very large offset. I have the SV-H set up at 215, and even with the SV at 215, the group is barely 198.
