 Test procedure
<1> Before starting a measurement, adjust the offset voltage of this product to zero according to
" 3.5.3 Fine output offset adjustment ".
<2> Set bias addition of this product to ON and change the dial gradually from 5.00.
<3> Measure the output voltages at scale marks of 0.71 and 9.29.
<4> After a measurement, set bias addition to OFF and set the dial to 5.00 for safety.
