7) Once you are done exploring the Setup Menu layout and operation, press the "Exit" key to
return to the main output screen.
DC Voltage
1) Connect the 8846A to the 5730A output terminals as shown in Figure A. The 8846A does not
have a Guard input terminal. You may leave the Guard cable disconnected.
2) Press the [DC V] key on the 8846A.
3) Enter 10 millivolts on the 5730A and output the voltage.
4) The 8846A should read approximately 10 mV.
5) Adjust the 5730A by rotating the knob until the 8846A displays exactly 10 mV. Notice which
digit is highlighted in yellow on the 5730A output. Change the output by larger or smaller
increments by using the
6) As you adjust the output, the touchscreen displays shows meter error in % or parts per
million (PPM). The reference value (10 mV) is shown on the left side of the output screen
and the error calculation is shown on the right. Compare the Error level to the Performance
Specification displayed in the top right of the touchscreen. (It may be in different units).
7) Notice that the 5730A is in the 220 mV range and in "Auto Range" as shown by the oval
located directly above the output voltage on the touchscreen. To lock the 5730A in the
current range, press the yellow dot to the left of "Auto Range." Now if you attempt to enter
an output value greater than 220 mV, an error message appears to inform you that the
calibrator is in a locked range. To change back to "Auto Range," simply press the yellow
button again.
Only DC voltage and DC current ranges can be locked. This ability allows the user to
maintain a constant zero value. This is needed for precision linearity testing of the high
performance DMMs.
