OK, technically, since its non-adjustable, all we can do is verify.
How can I be sure that the EGT gauge is reading properly? We discuss where is the best location...( closest to the pistons, IIRC). Do we all just assume that 1200 degrees is REALLY 1200 degrees?
Dunking it in boiling water will show 212 degrees at sea level--or close to it, but that is really low on the scale that we need. Is the temperature of just melting solder, or lead consistent enough to use that as a reference point?
Backstory---I am tasked with getting our soils and concrete lab "certified", meaning inspected to show that we comply with what the Standards require. Part of that process requires me to measure EVERYTHING we use and verify that I can trace the accuracy back to NIST. So I am sensitive to calibrating/ verifying EVERYTHING. What good would it do if I watch the EGT gauge religiously, and keep the readings under 1200 degrees if the real temperature is 1600 when my gauge says 1200?
My first impression is that thermocouples are pretty standard, and reliable. The voltage they generate is a repeatable phenomenon, and probably always right. I just want to be sure.
With snow-megeddon now occurring this question is more hypothetical than immediate---I am not going out in this weather, or the single digit temperatures that follow it to install the gauges.
