Editing and Error Output Settings
All Calibrator outputs can be edited using the front panel Edit Field knob and associated
L, W, and e keys. In addition, multiply X and divide D keys edit the
output by decades. The difference between the original output (reference) and edited
output is displayed as an "error" between the two settings. This allows you to edit a value
to achieve a correct reading at the UUT and thereby calculate an error in ±% or ppm
(parts per million) if it is less than ±1000 ppm. Table 4-2 lists the actions that cause the
calibrator to exit the error mode and return to the original reference output, or to output a
new reference, as selected.

How to Edit the Output Setting
When you initially source an output from the Calibrator, you enter a specific value. For
example, 10.00000 V dc. To edit the output value to suit your application, turn the front
panel Edit Field knob clockwise to increase the value or counter-clockwise to decrease
the value. (The Edit Field controls will not operate if you are in any setup function. Press
the P key one or more times to exit a setup function.)
To select a higher order digit, use an Edit Field cursor key L or W. The output digit
in edit is always underlined (see below).
The momentary display of the letter u in the Output Display when editing during OPR
(Operate) indicates "unsettled," that is, the Calibrator output is settling with a new value.
