The Square, Triangle, and Truncated Sine selections are useful to measure the
peak-to-peak output of multi-product calibrators like the Fluke 5522A which have
these non-sine wave outputs. See the screen below:

The bottom field, Shunt Corrections ON/OFF determines if the ac-dc differences
for the selected shunt are applied to the displayed current level, and the shunt
loading is accounted for due to the input impedance of the voltage measurement
circuit (10 Mohm in parallel with 80 pF). The main display indicates when
corrections are ON. Note that if set to OFF, an Instrument reset (under
Instrument Setup > Reset Instrument) retains the OFF setting. If the Product
is power cycled, Shunt Corrections is always set to ON.The Product uses a linear
interpolation of the loaded ac-dc differences between the frequency points to
make corrections. See the screen below:
