Use Error Mode

When error mode is entered from any output function except resistance, the least
significant digit on the Display is highlighted. Push  to enter error mode and select
the frequency line for adjustment first (but only if the frequency is not zero).
When the rotary knob is turned, the highlighted digit increments or decrements. Turn the
knob clockwise to make the number more positive. Turn the knob counterclockwise to
make the number more negative. As a digit is incremented past 9 or a digit is
decremented past 0, the adjacent digit is carried.  and  select digits to the right and
left, and selects the upper line (amplitude) and lower line (frequency).
If the output is adjusted beyond the capability of the Calibrator, the Calibrator beeps and
does not allow the change.
Push  and  to quickly verify the accuracy of different ranges of a UUT. When in
error mode and these keys are pushed, the Calibrator output and the new reference are set
to 10 times or 1/10 the previous reference value.
In the resistance output function, the edit controls show the UUT error in a similar way,
except the output of the Calibrator does not change as the knob is turned. Instead, a
reading on the display changes that can be matched to the reading on the UUT. As the
reading is changed, the Calibrator computes and displays UUT error.

Read the UUT Error: AC and DC Voltage and Current Output

To read the error of the UUT in the ac and dc voltage and current output functions:
1. Set the necessary calibration voltage or current, as previously described under "Set
2. Use the output adjustment controls as necessary to get a reading on the UUT equal to
4-34
the Output."
the original entry on the 5730A Calibrator. To increment or decrement a higher-order
digit, push . As the reference value is approached, work progressively back
towards the least-significant digit on the Calibrator display as necessary by pushing
. It is only necessary to go one digit past the least significant digit of the UUT.
Digits below that are beyond the resolution of the UUT. The UUT error is shown on
the display. This example assumes that the Calibrator is in the dc voltage function:
