8) To measure the OUTB voltage, connect the second

DVM between H2-3 (OUTB) and H2-4 (GND).

9) Verify that the voltage on both DVMs is approxi-

mately 0V.

10) Enter 0x3F into the D7 - D0 (Shift Register Data

Bits) edit box.

11) Press the Load All DACs button.

12) Verify that the voltage shown on both DVMs is
