set round to zero mode,

"Round to zero" is round mode 4, i.e. truncation (instead of the standard mode 0 that rounds to even).
The round mode is set by the RM command which is part of the MODE menu.

Round to 12 significant digits. This is accomplished by the RSD command that can be found in the X.FCN menu.

Yes. ;-)

So all in all it's a procedure like this:

Code:
RM 4                                  // set round mode to truncation [SCI] 11                              // always show 12 significant digits 17 [1/X]         5,88235294118 E-2    // 1/17 rounded 12-digit display precision [ENTER] RSD 12   5,88235294117 E-2    // first 12 digits [-]              6,47058823529 E-14 [ENTER] RSD 12   6,47058823529 E-14   // next 12 digits [-]              4,11764705800 E-26   // last 10 digits RM 0                                  // reset standard round mode
