We put three of these on various tools that we didnt want to spend the money on Proscales for. As with most of this imported stuff the manuals are pretty much useless. Im trying to decipher how you go about setting the DRO when you dont want to zero it but rather set it to a given value or dimension. For instance we put one on a roughing planer that we run occasionally and we run a board that measures .801, Im guessing you have to use the preset function to input .801 but doing that the DRO will sometimes read other erroneous dimensions.
The single page HF style "production instruction" sheet says "Use preset function to preset any desireable measurement reading under inch metric or decimal mode". What is a desirable measurement? The one you want? Your target dimension? etc.
