*RST sets Auto Zero to ON and Power Line Cycles to 1.
Set the DC Standard Output to 0.1 DCV.
1.
Set the HP E1411 range to 0.113 V (0.125 V with 10% overrange)

CONF:VOLT:DC .1
Measure the input with READ? and verify the results are within

specified limits (at the range selected for 1 PLC). Record results
on Performance Test Record.
Repeat steps 1 through 3 for the following DC Standard voltage

and HP E1411 ranges:
E1411 Range
0.91 V
7.27 V
58.10 V
300.00 V
Remove power and disconnect test equipment.

This example performs a DCV test for DC volts input and a power line
reference frequency of 60 Hz. Change line 80 to OUTPUT
70903;"CAL:LFR 50" for 50 Hz operation.
When connected to the HP E1411 multimeter, some DC Standards may
exhibit voltage variations at the start of a measurement. The WAIT 1
statement (line 150) provides a one second wait before measurement to
allow settling of the DC Standard output.
