Introduction
This section describes the front panel features of the Model 2010. For those measurement
options accessible only by a remote interface, refer to Sections 4 and 5. This section is organized
as follows:
• Measurement configuration — Describes ranging, filtering, relative readings, digits of
resolution, and measurement rate.
• Trigger operations — Uses a trigger model to explain trigger modes and sources.
• Buffer operations — Discusses the reading storage buffer and buffer statistics.
• Limit operations — Defines how to set reading limits.
• Scan operations — Explains the internal and external scanning capabilities.
• System operations — Gives details on setup saving and restoring, selecting a remote
interface, and accessing test and calibration.
Measurement configuration
The following paragraphs discuss configuring the multimeter for making measurements. See
the end of Appendix A for information about optimizing readings for speed or accuracy.
Range
The selected measurement range affects both the ultimate digits and accuracy of the
measurements as well as the maximum signal that can be measured. The range setting (fixed or
auto) for each measurement function is saved when changing functions.
Maximum readings
The full scale readings for every range on each function are 20% overrange except for the
1000VDC, 750VAC, 3ADC, 3AAC, 1MΩ two-wire and four-wire, and diode test ranges.
Input values more than the maximum readings cause the "OVERFLOW" message to be
displayed.
Manual ranging
To select a range, press the RANGE ▲ or ▼ key. The instrument changes one range per
keypress. The selected range is displayed for one second.
If the instrument displays the "OVERFLOW" message on a particular range, select a higher
range until an on-range reading is displayed. Use the lowest range possible without causing an
overflow to ensure best accuracy and resolution.
Note that the temperature and continuity functions have just one range.
