Displaying the Output Error
When you edit the output value, the Control
Display shows the difference between the
reference value (the value you originally entered)
and the edit value (the value shown in the Output
Display), displaying error difference in parts per
million (ppm) or percent (%). For example, if ERR
UNI is set to > 100 ppm, the error will be displayed
in ppm up to 99 and then the error will change to
0.0100% at 100 ppm. This allows you to edit the
output such that the UUT displays the expected
value and thus give an indication of the UUT
accuracy
.

For example, the edited difference of 0.00030 V
for an output of 10.00000 V represents
0.00030/10.00000=0.000030, or 30 ppm.
