The following pages show you how to make measurement connections and how
to select measurement functions from the front panel for each of the
measurement functions.
• After measuring a high voltage measurement of up to 1000 VDC, you are recommended
to wait for approximate two minutes before measuring a low-level measurement with
1 to 10 µV resolutions.
• After measuring a high current measurement using the A input terminal, you are
recommended to wait for approximate ten minutes before measuring a low-level DC
measurements of volts, amperes, or ohms; to achieve accurate measurement. This is
due to the thermal voltages generated during the high current measurements that may
cause errors when measuring the low-level measurements.
