Auto Range Versus Locked Range
A softkey is supplied to toggle between the ranging methods auto or locked. This feature
is available only for single-output dc volts and dc current outputs.

When you select auto (the default), the Calibrator automatically selects the range that
gives the best output resolution. When you select locked, the Calibrator locks the selected
range and will not change ranges when you edit the output, or record new outputs. Values
lower or higher than the locked range are not permitted. The locked selection is typically
made to prevent range changes that can cause a small perturbation in the output, for
example, when you measure the linearity of a given multimeter range.
Set Output
To set the Calibrator output, push the keys for the necessary values and then push a units
key to identify which of the volts, amps, hertz, etc., that the values are for. The control
display shows the value and units you select as you type them into the Calibrator. When
you are satisfied with the value and units, push
. If the output display shows
STBY, push
to output the selection. A small “u” (unsettled) in the Output Display
shows that the Calibrators internal circuitry must become stable.
For example, to set the output to 10 V dc, push:

To set the output to 20 V ac at 60 Hz push:
