User manual

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.
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.
The full scale readings for every range on each function are 20% overrange except for
the 1000VDC, 750VAC, 3ADC, 3AAC, and diode test ranges.
Input values more than the maximum readings cause the "OVERFLOW" messages to be
displayed.
To select a range, simply 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 high-
er range until an on-range reading is displayed. Use the lowest range possible without caus-
ing an overflow to ensure best accuracy and resolution.
Note that the temperature and continuity functions have just one range.
To enable autoranging, press the AUTO key. The AUTO annunciator turns on when au-
toranging is selected. While autoranging is selected, the instrument automatically chooses
the best range to measure the applied signal. Autoranging should not be used when opti
-
mum speed is required.
Note that up-ranging occurs at 120% of range, while down-ranging occurs at 10% of nom-
inal range.
To cancel autoranging, press AUTO or the RANGE or key. Pressing AUTO to cancel
autoranging leaves the instrument on the present range.
The AUTO key has no effect on the temperature, continuity, and diode test functions.
