Lead acid batteries - Measurement of internal resistance - Code

While working on a small hardware modification to improve the resolution of measurements it occurred to me that displaying an internal resistance of 0.2 ohms as 200 was easier to read than 2. I updated the code over on  Hackaday

Debugging a change like this is so easy with Forth, especially when a simple x100 instruction fails because the 16 bit integer maths overflows.

ps the hardware mod worked a treat giving a fourfold improvement in resolution. I'll describe it shortly once I've finished the soldering. It might even mean that no modifications to the board are required!
