3.5 Setting Sampling Rate
30
The sampling rate can be selected from FAST, MEDIUM, or SLOW. Slower
sampling rates generally provide greater measurement precision.
Execute zero adjustment before measuring to nullify any residual offset voltage
from the instrument or measurement environment. Measurement accuracy spec-
ifications are applicable after zero adjustment. Zero adjustment can also be exe-
cuted by the 0ADJ terminal of the EXT I/O connector.
See "5.2 Signal Descriptions" ( p.76).
Before executing zero adjustment, connect the test leads (probes) as follows:
1. Connect SENSE-H to SENSE-L.
2. Connect SOURCE-H to SOURCE-L.
3. Connect the joined SENSE and SOURCE leads together as shown below.

• When SLOW sampling rate is selected, self-calibration is executed during
each measurement. At other sampling rates, self-calibration is executed
manually or automatically every 30 minutes.
See "4.9 Self-Calibration" ( p.69).
• Refer to the specifications for details of sampling time.
See "Sampling time" ( p.166).
