Just a curiosity of mine. I have a Fluke 287 and was wondering how difficult it would be to convert to the 289. The firmware is the same for both and the electronics are nearly identical. There was a short-lived meter called a Fluke 189II/AN that was the predecessor to the existing 287/289 meters. According to the attached picture from the service manual for that early meter, there is a set of model selector resistor dividers. Anyone know what effect these have?

Even if you can make the electronic identical it still not the 289. The 289 dial has 2 extra positions for low Z and Low Ohm. I think the best conversion is to sell the 287 on Ebay and buy a 289 on Ebay.

the same was apparently done and working for a 187 to 189 conversion, thread here ..... to my knowledge, never been done for a 287 to 289 ...
