As Turner correctly says, IR is calculated during charging. There is no need to use a special mode to get the pack IR. Just read during a charge. You can also do a short charge to get the IR on pack that you just want to take a reading on. Both the Powerlab6 and the Powerlab8 operate the same way with regard to IR.
