Digits
The display resolution of the measured reading depends on the DIGITS setting. The default display
resolution setting is 6.5 digits. The DIGITS setting selects display resolution for all measurement
functions.
The DIGITS setting has no effect on the format of readings returned by a print() command over a
remote interface. For information to adjust the format of remote interface readings, see
format.asciiprecision (on page 11-89).
The number of displayed digits does not affect accuracy or speed. Accuracy and speed are controlled
by the SPEED setting (see Speed (on page 4-60)).
Setting display resolution from the front panel
To set the display resolution, press the DIGITS key until the correct number of digits is displayed.
Available display resolutions are 4.5, 5.5, and 6.5 digits.
