Pop on cold atty which reads 0.14 across multiple ohm meters. DNA 200 invariably reads this as 0.16. Fifteen minutes later, the reading drops to 0.15 and it is only after a few hours of sleep and refinement when the correct reading of 0.14 is reached. Is this normal? 510 threads and pins on both the device and atty are confirmed clean (visually and by way of cleanings with DeOxit D-Series). What are some best practices for obtaining accurate cold resistance readings in the shortest amount of time?
