8.
Set the calibrator voltage to the test point value specified by the
Test Point entry on Table 3.
9.
Read the voltage from the DMM. Record the actual DMM reading,
which is
output1
, and the calibrator output voltage, which is
volt1
,
for later use.
10. Set the calibrator to the negative test point value for the same gain.
Skip any test point voltages that are specified as 0 V. You need only
upper and lower limits for adjustment.
11. Read the voltage from the DMM. Record the actual DMM reading,
which is
output2
, and the calibrator output voltage, which is
volt2
,
for later use.
