 Conventionally a thermocouple is created using two dissimilar metals that join, and then the other ends of these metals are terminated to copper contacts. These copper contacts are also part of the construction of the thermocouple and are referred to as the cold junction.
 As there are these extra two joins between the thermocouple wires and the copper; these also have properties of their own in their reactions with temperature.
 
-If the cold junction is held at 0 degree's C, then their effect is considered to be null, and so they can be ignored. However, in the real world the joins to copper are often at room temperature, and as such the measured voltage from the thermocouple must be compensated to remove the influence of these joints. This process is often called cold junction compensation.

 If you analyse one of the open circuit schematics (Pinecil, TS100, TS80) they all use the same approximate formula.
 This consists of an op-amp that is connected directly across the heating connections to the tip, and a separate handle temperature sensor.
 
-When the iron is **not** heating the tip, the microcontroller uses the ADC to read the output from the op-amp. This produces a voltage that _should_ be linear to the temperature of (tip-handle). This value is then offset compensated (to remove ADC+op-amp offsets), and then converted into a temperature delta in C/K. This temperature delta can then be added to the handle temperature to derive the tip temperature in C.

This makes sense as these tips are cheap and would have made an excellent design for Miniware to have cloned in making the TS100 in the first place.

 This is why sometimes the temperature may flick around a little during use but the tip temperature itself is quite stable. The thermal mass of the tip smooths these small amounts out nicely for the user. Though seeing larger jumps on some tips than others _may_ indicate that the tip does not have optimal internal thermal bonding between the heater coil and the tip itself.
 
-The firmware uses the theory that these irons are more towards the power users territory than most, so it tries to not hide the actual temperature.

For example, on a digital Weller unit Ralim has to hand, if set to 350C, it will regulate to within around +-3 C but not indicate you are outside of this bad until you exceed +-5C. This gives the illusion that it's holding the temperature perfectly when in actuality it's moving around as well.

 The firmware only accounts for cold junction compensation and then treats the remaining error as being a constant offset. 
 While the error is small, it is actually composed of both a constant offset as well as an offset that is linear to the handle temperature.
-This offset that is linear to handle temperature is as of current not modelled into the firmware and there is assumed to be constant. This is generally "close enough" as once the unit is in use, the handle temperature is usually within 10C as the components inside warm-up from use. This means that this error is "relatively" constant once the unit is being used. However, this can cause odd behaviour when the tip temperature ~= room temperature. And can cause some jumping and movement in the readings when attempting to control the tip to sub 100C.
