1 Select each function and range in the order shown in the table below.
Before executing each test, you must press to enable reading
monitoring on the selected channel (or use the ROUTe:MON command
from the remote interface). Compare measurement results to the
appropriate test limits shown in the table (see page 74).

Q: Quick performance verification test points.
Note: Zero offset calibration using a multifunction calibrator is
NOT recommended. The calibrator and cabling offset can be large
and unstable causing poor offset calibration of the internal DMM.
