value is to be within 7.8 mV (lower spec) and 8.2 mV (upper spec).
NOTE
Averaging will complete faster if you exit the measurement menu
and then return when averaging is complete. Alternatively,use the
dial to move the Main Size setting two notches higher than the
default setting.
+'# +Change the polarity of the voltage differential coming from the
precision voltage Source. Check that the DMean value is between
-7.8 mV and -8.2 mV.
