There are two ways to change adjust the calipers on the TS-2 that give you a
rough idea of whether the wheel is dished properly. Instructions can be
found here -- http://www.parktool.com/
Always use a redundant method of checking wheel dish and don't trust the caliper arms. You can use a dish gauge or flip the wheel around in the stand--even if the caliper arms on your stand are misadjusted a centered rim will be in the same relative position to the misaligned arms no matter which way the wheel is turned.
