1. Execute the ACAL DCV command using the front panel "Auto Cal"
key and scroll keys. This auto calibration will take approximately
two minutes to complete.
2. Configure the transfer standard DMM as follows:
-- DCV
-- NDIG 8
-- NPLC 100
-- Trig SGL
3. Configure the DMM under test as follows:
-- DCV
-- NDIG 8
-- NPLC 100
-- Trig SGL
4. Set the range of the transfer standard DMM to 10V (function = DCV).
5. Set the range of the 3458A under test to 10V (function = DCV).
6. Connect the DC voltage source to the transfer standard DMM.
7. Set the DC voltage source to 10V
8. Execute Trig SGL and read the output of the DC voltage source as
measured with the transfer standard DMM and record this reading in
the "Transfer Standard Reading" column of the DC voltage
Operational Test Record.
9. Remove the connection from the transfer standard DMM to the DC
voltage source.
10. Connect the 3458A under test to the DC voltage source.
11. Execute Trig SGL and read the value as measured with the 3458A
under test and record this value in the "Unit Under Test" column of the
DC voltage Operational Test Record.
12. Connect the DC voltage source to the transfer standard DMM.
13. Repeat steps 8 through 11 for a -10V DC voltage source output.
14. Calculate, and record in the column provided, the difference (absolute
value) between the transfer standard DMM reading and the unit under
test reading.
15. If the difference calculated is greater than the specified limits, refer to
