I purchased this soldering station some time ago:
https://www.amazon.ca/Sigma-60D-Lead-Free-Soldering-Real-time/dp/B00MBQ41NS. So far it's been working great! Came with extra heating elements, fuse, tips, solder sucker and an ESD wrist strap. It heats up really fast, and has a calibration feature of dubious quality.
There is one thing that bothers me, there is a decimal point after the temperature that occasionally blinks. As mentioned in a few of the reviews on that amazon page, no one (even the manual) knows what this does. Some have speculated that its an up to temp indicator.
I'm wondering if anyone has this station and could scan the manual (I've misplaced mine), and might know what this indicator means.
