Hi all,
I've got a 590 a little less than a month old and have a couple of issues I'm trying to figure out on. The first is the RTD probe calibration. I used 3 thermometers (the 2 meat thermometers and an old school oven thermometer) to measure the temp at the grate. The built in meat thermometers were an average of, 15ish degrees warmer and so I tried to use the offset to adjust based on the percent difference. I did that (adjusted 6% higher) and it only changed a few degrees. The original temp was 250 so it should have changed by 15 degrees, but it only went to 253. Tried it again at a different temp of 180 and same issue. What am I doing wrong here?
The second are the actual meat thermometers. I'm calibrating them using the ice bath method, but at higher temps port A deviates by as much as 5-10 degrees compared to port B and a control thermometer. Again, am I doing something wrong with the calibration?
Finally, I think I had some surface rust. I cleaned it off using barkeepers friend and what's below is what's left over. This is the left side of the barrel next to the hopper. Is this normal? It's used under a covered patio and I use a cover when not in use.
What does everyone think?
