I see under "Electronic accuracy" on page 1-5 of the Model 218 Temperature Monitor that the accuracy in mK have been pre-calculated for some temperature points.
±318 mK at 30 K
±152 mK at 77 K
±212 mK at 300 K
±299 mK at 675 K
±328 mK at 800 K
The electronic accuracy is stated as ±0.06 Ohms ±0.02% of reading.
I'm assuming that the 0.02% of reading at 30 K is ±0.006 K, leaving a remainder of ±0.312 K
How is the rest of that calculated? I'm currently trying to come up with an accuracy statement for several data points when using a PT-100 probe and I can't get the math to work out properly when checking it against the given points I've listed above.
