4.1 Measurement configuration
4.1.1 Range
You can let the multimeter automatically select the range using auto ranging or you can select a fixed
range using manual ranging. Auto ranging is convenient because the multimeter automatically selects
the appropriate range for each measurement. However, you can use manual ranging for faster
measurements since the multimeter will not have to determine which range to use for each
measurement. The digital multimeter returns back to auto ranging when power has been off or after a
remote interface reset. Note that auto ranging is not available for some measurement functions and
ranges.
Manual ranging
To select a range, simply press or key. The instrument changes one range per key press.
The selected range is displayed momentarily before showing the measured readings.
If the instrument displays the “OVR.FLW” message on a particular range, select a higher range until an
in-range reading is displayed. Use the lowest range possible without causing an overflow to ensure best
accuracy and resolution.
Autoranging
To enable auto range, press key. The AUTO annunciator turns on when autoranging is selected.
While selected, the instrument automatically chooses the best range to measure the applied signal.
Note that up-ranging occurs at 100% of the range, while down-ranging occurs at 10 % of normal range.
To cancel auto range, press or or key. Pressing to cancel auto range will
leave the instrument in its present range.
The key has no effect on the continuity and diode test functions.
